The WIFI part should really be in the center of the house. Now, you have to look at line of sight obstructions like thick walls etc. You can use a repeater to handle the dark spots. Generally the repeater needs the MAC address of the signal it's repeating. The repeater only needs a wireless connection.
 
In my case, I had trouble getting a decent WIFI signal sitting in a chair until I added a repeater about 3 feet from the chair. The repeater allowed coverage in the yard.

As a data point (and this is from a friend, not personal experience): My
friend was a Comcast customer a few years ago and was getting decent speeds
out of the Comcast interface, but noticed that they had started dropping to
the extent that snailmail would have almost been faster than email.
 
Unfortunately for Comcast, this friend is the head of the networking
department for our common employer, so one weekend he took home some of the
test equipment to see what's going on.
 
To make a long story short, what he found was that on the Comcast link:
*every* router he looked at:
 
* had the default SNMP community strings [passwords] for both read and
write.
* was significntly downlevel, well below the version for critical fixes
* was running at 100% CPU
* was infested with malware.
 
...which explained his problem.
 
Comcast's response when he notified it of the situation? "You're not
supposed to do that!!!"
 
My friend is now a very satisfied FiOS customer.

I have an "Xfinity" Technicolor TC8305C.
That seems to be the brand name for those made by Motorola (if i
remember correctly) and sold to Comcast.
Arris is another brand name.
As far as i can tell,about 90 percent of production goes directly to
Comcast.
 
One model/style has no Wifi, and the other has it; otherwise they all
seem to be the same beast. Rental rate is the same; sales price cannot
say; i got the WiFi version for about $100, saving me $20 year one.
 
There is no "preferred" channel; let the modem do the assignment
automatically (for best signal).
 
There are re-sellers where you can buy exactly what your cable
provider offers. I suggest you do not rock that boat for a few months
and look at the bill CAREFULLY to find the exact monthly rental charge.
If in the region of $10/month or more,then buy the exact same model
for around $100. Pays for itself in 10 months..
Those resellers may have specs or know where you can get them.
 
The installation instructions CANNOT work (read them and you will see
what i mean).
You will have to call your cable provider and get them to add its MAC
address into their database and activate it; else it CANNOT WORK.
Once you are satisfied, if at all possible, PHYSICALLY return their
modem to one of their sales centers AND GET A RECEIPT (!!!_VERY_!!!
important). If not, see if you can wangle a shipping label from them (as
a courtesy because you are UPGRADING the service).
Without that receipt, they can continue to charge monthly rental fees.
 
Get your phone service from the same cable internet provider; the
phone service alone will be less than landline.
In fact, that is why i switched from copper (POTS) to cable,as the
loco phone bastards were raising the rate every other month; i wound up
saving money.
 
Allowed me to switch from modem (144K in reality, NOT the advertised
or bally-hooed fake rate) to cable at a respectable speed.
Plus...i now have unlimited long distance at NO extra cost.
 
Mind you,i did not have TV and still do not have it.
Adding TV service on the cable is expensive as far as i am concerned.
So,,if you HAD TV from your cable provider, adding internet and phone
will not be that much more(*).
If you are close enough to the transmitting stations (ASSuming no
reflections to bugger signal), you can put up our own antenna and get
them free (like the GOOD OLD DAYS of analog).
 
(*): IGNORE ALL ADS that quote some bullshit price; actual cost is
always about TWICE whatever the ad says.

Over a 12+ year period, Comcast slowly raised the modem rental rate
from the $5/mo to $10/mo. Ever hear the story about the frog in the pot
over the fire?
Got my own modem,EXACT same brand and model (heck it even says
Xfinity on it) for about $100.
So i can say i am saving $10/mo now that it has paid for itself.

YES>>>Motorola makes almost all of the modems sold to Comcast (and
prolly Spectrum as well).
Model brand names vary,but they is the same beast, so if what you buy
on the net is the same exact brand and model that they use,then they
HAVE TO have it on their approved list; they cannot dis their own stuff.
$100 for your own modem and no $10/mo gives a 10 month ROI; no brainer.

Exactly why i OWN my own modem.
The day i got the notice in the mail about 2 or 3 years ago in Maine.
I went out and bought my own Motorola modem off the approved list got the
best one that DID NOT have wireless i don't use it .
and love the savings and the speeds as they allow channel bonding in my area
any ways so i get double the normal download speeds most of the time.

Same here, except I got a WiFi "SurfBoard" model.
 
While I was at it, I had mentioned that a cable modem wasn't really a
modem after he asked me if I needed a modem. I had already given him
that "approved" list provided by Time Warner Cable for compatibility
with their system. They, of course, call them all cable modems.
 
He argued with me! Right or wrong, salesmen shouldn't argue with
customers. Cable modems have more in common with TV transceivers than
they do with modems. I asked him if a smartphone was a modem, and he
said no.

I had a modem, but it didn't do the telephone thing. The installer did
everything with their modem, including patching into our phone lines,
and setting up all the cable boxes, and I thought that was a good
deal. I have plenty of electronic projects already.

In my neck of the woods Verizon can't find their keisters with two
hands, a map, radar etc., whereas Optimum is right on the ball. We
soldiered on with V. for a long time despite hours spent in call
forwarding purgatory that never resolved anything, billing snafus,
clueless office droids, and an apparent total lack of communication
between their residental and commercial operations. The only reason
that I did that was because I really wanted to keep the copper POTS for
use during blackouts. I finally decided that I didn't trust an
operation that clueless to know how to run a legacy central office
battery system, so that the whole thing was sort of moot.
 
In 5 years with Optimum I've had exactly one trouble. Within half an
hour, they had somebody on my premises who actually knew what he was
doing, with an apprentice in tow learning the ropes. Fifteen minutes
later they had it patched (reprovisioned somehow so that I had 25/5 Mbps
again) and the trouble outside was fixed the same day. A couple of
times a year, V. sends salesmen to visit, and I try very hard to
restrain my impulse to greet them with howls of derisive laughter, not
totally successfully.

They were unopened until today, when I ripped open the left side to

They're marked with a 7 shelf life. I'm only 2.7 years over the 2014
expiration date, but have no idea when I bought them. I guess it's
"use them or lose them" because I stupidly used up newer battery
packages before diving into the older batteries buried in the back of
the battery "shelf".
 
Grumble, and $15 gone. Oddly, most of the batteries I pulled out and

That's nothing. You probably have your first dollar and you got better credit than at least 90 % of the population in this country.
 
But I do understand that $15 is probably $20 today. That can probably still get you a bag of weed over there in case you happen to smoke it.
 
Anyway, I think we have to see by now that batteries leak whether you use them or not. When depends on the brand I guess, or not so much. Maybe the manufacturer. The company that sells Duracells is probably not in the US so they probably have them made elswhere. Hell, Union Carbide was doing that in India when my sister still needed a fake ID to drink. Boy if I had some money when their stock dropped like a rock I could have made a nice little pile.
 
Speaking of which, how come that package says "Piles" on it ? Is that some foreign word for batteries ? In fact those aren't even batteries technically, they are cells. A battery means a bunch of them like a nine volt. But like alot of words in this country, they are used incorrectly, but once accepted the thing is that the listener understands the speaker. But I have never seen the word piles on anything of the sort.
 
We have to treat them like electrolytic caps I guess. I have read plenty of people reporting that they leaked without ever being used.

That is French for Battery ( or some such equal word). I bet if you
look at the packge you will see some other words that may not be spelled
in American English. Probably more French. That is to save from
printing seperate packages for different languages.
 
 
Not sure how it relates to the modern usage,but the old batteries were
called Voltaic piles in honor of the man Volta that had a lot to do with
the first batteries (cells).

It was a $2 bill and it disappeared in a move long ago. I replaced it

Yep. I am authorized by my predatory bank (Wells Fargo) to dig a
bigger hole for myself and bury myself in it. As I get older, my
credit improves even though my income has dropped. That's because the
bank knows that I'll probably die before I pay off any loan and they
can then grab the collateral.
 
>But I do understand that $15 is probably $20 today.
 
Sorry. I don't recall what I paid. I just looked up what a 48 AAA
box is currently selling at Costco. If it's really 10 years old, then
I probably only paid about $10.
 
>That can probably still get you a bag of weed over there in

You would not believe how many retail "medical marijuana" places we
have in the area. At the present rate, they'll outnumber tattoo
parlors and electronic smoke shops. Looks like all I can get for $15
is a gram or two:

I had previously proclaimed that Costco Kirkland batteries leak less
than Duracell batteries. Now, I'm not so sure. I guess the next
questions are what makes them leak and how do I prevent leakage?
Refrigeration?

Dunno. A "bank" of batteries has always be referred to as a "pile".
<https://en.wikipedia.org/wiki/Voltaic_pile>
Note: This has little to do with my reference to a disorganized web
site as a "web pile".

Thanks. I never thought of it that way. Sounds right.
However, words and phrases have a tendency to change meaning. If you
call a cell a battery often and long enough, the definition can
change.

Yep. As with drugs and foods, an expiration date is a nifty feature
for the manufacturer. Toss the battery out before it goes bad. Or,
like the bulging electrolytics, toss the entire product out before the
capacitors trash it. Kinda like a built in warranty timer.

>"That's my lunch plus a tip. "
 
That's not an expensive lunch here. I can imagine there, perhaps a sandwich and bag of fries. And you probably want something to drink so that cuts into it even more.
 
I haven't gone out for lunch in years, everybody just pays through it if you eat there, at least where I have worked. Which brings us to a cute little true story.
 
I lived in Cleveland and worked in Willowick which is about 23 miles to the east. Show was getting more and more business even though we were seriously high performance. i did three times the work of my predecessor, and (maybe unfortunately taught them what to expect from a real tech) still it got to the point where we could not keep up with it.
 
I didn't drive, I have had license problems for a long time, but only recently did I stop driving due to my eyesight. anyway he gets introduced to me as "another Electrasound graduate". Electrasound was factory service for almost everyone back then. They required a very high level of competence and had the over 100 page test to prove it. i beat 154 other applicants and got the job, as well as rewrote their test. There was a question they give you the schematic and some voltage readings and wanted you to put numbers by the answers instead of just checking them off. Well I found an option they should have included but didn't. It got to the service manager and he said "Damn, he's right".
 
So between the two of this at the later company we had plety of clout. the boss would ask what we want for lunch and actually go get it for us. In retrospect I think we could have made them pay for it as well but that didn't occur to us.
 
So one day Rich (the other Electrasound graduate they called us)and I decided we wanted to go out for lunch so we went to the Ground Round for a few beers and some surf-n-turf. When it came time to go back to work Rich says "I don't like how he said "you guys won't come back" and i said "Me too". Then I forget who said it but "Know what we should do ?". So guess what we did. Now only that we called the shop and told him we need him to bring down about fifty bucks to pay the tab because we were caught short. His answer ? "I can't leave right now because everyone else is gone on the road". That was a lie but it was so much fun. Then we went to the strip joint after we caught a good enough buzz. Back then in Ohio you couldn't have nudity and alcohol in the same business.
 
I digressed greatly, I will get serious in another post.

The difference between Duracell/Eveready/US-Made batteries is that if the units kill something, the Manufacturer will replace or pay. I received a check for $378 and change, representing the cost of a Geiger Counter that I purchased for $50 at surplus, when a pair of Eveready batteries self-destructed inside. They even refunded the cost of shipping the unit to them.

Impressive. I managed to get about $20 from Eveready and $30 from
Mallory for trashing various Maglites. I've filed a few random claims
over the years, that usually get disappeared by the manufacturer.
 
>Otherwise, one is SOL and deserves _exactly_ what one gets.
 
Really? You seem ready to accept failure as inevitable and
inexorable. I think otherwise.
 
Ever wonder why there are alkaline cells around that live a normal and
useful life well beyond their expected lifetime? I've seen plenty of
really old alkaline batteries that simply discharged their coulombs
gracefully without a hint of leakage. Perhaps I'm using more alkaline
batteries these days, but I don't seem to recall such massive a
leakage problem during the 1970's. I certainly don't recall seeing
any leak in the original packaging.
 
It might also be useful for you to consider the possibility that the
leakage problem might be artificial and might easily be fixed by
better sealing methods or construction methods. This explains the
failure mechanism (hydrogen gas outgassing rupturing the vent seal).
<https://en.wikipedia.org/wiki/Alkaline_battery#Leaks>
Now how hard would it be to make a better seal, or direct the gas away
from the electrolyte? I would be tempted to conjure a conspiracy
theory that this failure mode is intentional, since it sells plenty of
batteries. Why fix something that produces sales?

Bluntly, this happens to consumers because they are either careless or lazy and would rather complain than take effective action. Battery makers, in my experience jump all over themselves to make customers happy. Do you think, after my experience I would ever buy a second tier battery?

Right. Blame the victims. To most consumers, batteries are a
commodity item, where the various manufacturers and labels are
interchangeable. Perhaps an astute buying might read reviews or run a
few tests, but the GUM (great unwashed masses) will tend to buy the
same brand of battery repeatedly even when faced with demonstratable
failures, leaks, counterfeits, and marginal warranties. The Energizer
rabbit probably sold more batteries than any magazine or online
battery review.
 
Also, "effective action" usually follows a complaint. More
specifically, I have had a vendor spontaneously provide effective
action or financial compensation without me providing a suitable
complaint. Even if I were "careless and lazy", I can still produce a
suitable complaint, which just might produce "effective action" by the
battery vendor or manufacturer.
 
>Battery makers, in my experience jump all over themselves to

>ever buy a second tier battery?
 
Yes, I do think you would, if you didn't know it was a second rate
battery. That happens all the time, when a manufacturer outsources
their production to the lowest bidder, changes supplier, or simply
cheapens the product. I can supply examples if you need them. I have
no idea what company manufacturers Kirkland batteries, or even if it's
only one company. Volume manufacturers usually have multiple
suppliers, between which they arrange bidding wars to produce the
absolute lowest possible price. A drop in quality is implied, but
never mentioned. If it lasts the warranty period, it's good enough.
In this case, the Kirkland batteries probably lasted the required 7
year shelf life.
 
If you were a Prepper, who stores batteries for some future
Armageddon, shelf life would be a major issue. Devices with low drain
and low duty cycle, where the battery would be expected to last well
beyond its shelf life is another problem area. For these users, there
are better types of cells available, such as Lithium AA at 5 times the
cost of alkaline cells. However, for the commodity applications,
alkaline cells are cheap, commonly available, cheap, fairly reliable,
cheap, warranties, cheap, and did I mention cheap? So for your
commodity applications, where a $2 cell is not an economical option,
you're stuck with the $0.40 alkaline cell. Yes, I think you will be
buying 2nd rate batteries, unless you can find a genuine leak proof
alkaline for the same price.

Now, here is where you go off the rails. When one purchases a 'house brand' to save a few pennies towards a critical application, the consequences of such a choice are to be factored into it. "I have no idea what company..." means that you accept without qualification or complaint that these devices may be second tier.
 
And that is exactly my point. Batteries, whether in use or not are wearing parts - just like tires. In an urban setting or areas where there are elevated levels of ozone, tires 'age out" in anywhere between 3 and 6 years depending on the type and composition. Those who do not keep this in mind are taking their lives in their hands.
 
Battery manufacturers make their batteries *JUST* good enough to support their price-point, and no more. Those that do not support an infrastructure that provides warranties and replacements are at a significant advantage. And, like lemmings, the great unwashed gobble them up based on price, alone. Then have the temerity to whine and pule about the results.
 
Two things - one philosophical, one very practical: If that first package of underwear at $3.29 from China stayed on the shelf for the $3.69 package made in the US, life would be different in this country today. But, no, the great unwashed gobbled them up, saving that $0.40. Little did they realize or care that their neighbors lost their jobs thereby *UNTIL* their own jobs were threatened - and you could hear them howl three states away. Do you want to give up a small, but vital technology to the Chinese? Do you want it such that your flashlight/radio/game depends on a 12,000 mile supply line crossing (at least) one ocean?
 
Lastly, do you know that there is not one single LCD device manufactured in the US. Not one. That Boeing aircraft would have analog controls were it to depend on US sources. Or, that fighter jet, gauges in a nuclear submarine. The US does not even have the tooling or basic infrastructure to make LCD devices were the need to arise. It would probably take 2-3 years to ramp up. So, yes, we can entirely lose vital industries by neglect, ignorance or by simply not recognizing the implications.

I assume you've got your test prods directly on the pads so you know it's
not just a dry joint?

Yes. But making that mistake isn't beyond me, by any means. It's a very
well-assembled board (I didn't do it), but well designed, too (I did it
-- and I'm modest, just ask me).
