"tony944" <tony@seput.com>: Sep 07 10:29AM -0700 I am lost on the questions and answers that you guys are posting. I never hear of different WiFi to me all are universal speed depend on your OS system, and the host and router if in use. as much I know all laptops have capability to hook to WiFi but you will need password unless system is open. no to many of those around but you can be lucky.   "EwaldBöhm" wrote in message news:msja29$5ft$1@news.mixmin.net...   How can we tell from an HP WiFi card spec whether the NIC is 2.4GHz or 5GHz, or both?   I'm trying to help my sister buy an HP laptop on the web.   My problem is that I contacted HP Support (via their chat mechanism) because USA phone support is not open now, and technical support isn't open tomorrow.   All I want to know is HOW to tell if a WiFi card has both 2.4GHz and 5GHz.   For $300 at Costco, plus $30 for shipping, this seems to be a decent 15.6-inch display laptop: http://www.costco.com/HP-15z-Laptop-|-AMD-E1-|-Windows-10.product.100222779.html   The main drawback from that Costco offering is that the WiFi isn't "ac", there's no mention of bluetooth, and the laptop doesn't come with Office 2013.   But, we can fix that at the HP web site.   If we go to the HP site to buy it, we can customize it to add what Costco doesn't have (and get free shipping). http://store.hp.com/us/en/pdp/Laptops/hp-pavilion-15z-laptop-m7d88av-1#!&TabName=specs   0. We start with the HP price of $350 which comes with twice as much memory as Costco's (4GB -> 8GB) plus free shipping (worth $30), so it's only $20 more than the Costco price. 1. We add the Microsoft Office Home & Student 2013 from HP for an extra $140 (either boxed, or already installed - I suggest they get the box for easier re-use later). https://store.hp.com/webapp/wcs/stores/servlet/CTOAddonsView?partNumber=QM4342 2. We add a WiFi "ac" card from HP for an extra $30 but is it dual band, 2.4GHz and 5GHz or not? 3. We add an extra wireless mouse and keyboard (no wires!) for $30 (because my sis wants that). https://store.hp.com/webapp/wcs/stores/servlet/CTOAddonsView?partNumber=LV290AA%23ABA The resulting price is $550 + tax (free shipping).   For that price, I see she gets a good laptop, but I chatted for half an hour with the HP sales chat people and they couldn't confirm if this 802.11 n/ac laptop has both 2.4GHz and 5GHz or if it only has one of those two frequencies.   HP chat sent me this URL but it just confirms that both "ac" and "n" don't have to be dual band; either one can be a single band. Also, it confirmed the 1x1 or 2x2 or 4x4 just means the number of dedicated data transmit and data receive antennas, which says absolutely nothing about the frequency. http://www.intel.com/content/dam/www/public/us/en/documents/pdf/next-gen-80211ac-wifi-for-dummies.pdf   My question is ... How can we tell from the HP WiFi card spec whether the NIC is 2.4GHz or 5GHz, or both?

So, it'll be dual band card, 2 stream one(2 antennas) Full -AC needs 4 antennas and there are almost no such thing yet for users. Of course it'll have Gbit Ethernet controller too. Does it have Bluetooth? Bluetooth mouse and keyboard? 8 GB memory is good. You don't have to spend 140.00 on MS Office. Freeware Openoffice is compatible with MS Office. Let her try it and you can buy MS later on student discount. And what cpu, and Video controller?(what is native resolution?) I am sure the laptop will have HDMI port and sufficient no. of USB port. And my(very robust game machine with enough cpu and video controller power) daily use laptop is 14", i7 quad cpu, 8GB memory Nvidia 740M video card and DVD r/w drive, etc. gotten for ~500.00 on eBay. Built-like tank. Never let me down. I never owned HP laptop. Personally I just don't like it. But I used many different Enterprise grade HP work stations or server. Most people use Intel 7260 dual band WiFi card. I have it in all our laptop except my wife's Asus GX60 which has Bigfoot Killer N card. I seldom use desktop any more. At home I use 17" Asus ROG with SSDs, 16GB memory, Nvidia 840m video card, i7 quad cpu, Blue ray R/W drive, etc. I use this for my real work. triple boot, W7 x64, Ultimate, W10 Pro and Ubuntu. (What real work? I am retired old fart, LOL!)

Long story. Experience. Nothing else is Microsoft Office. You and I can handle any office lookalike program, but teachers can't. Office 365 is stupid, for anyone buying only 1 copy of Home & Student, and who is still using Office 2007, which means they'd pay for Office ten times over with the subscription than with the one price.   Back to the "a", which is 5GHz and "g" which is 2.4GHz. What if it's 802.11 b/g/n/ac ?

Maybe not. Jeff just explained that only "a" has 5GHz. The rest can be 2.4 GHz.

Office 365 can be installed on 5 machines. If the skool has 5 machines of any type, which makes the price for each machine about $20/year. <http://www.microsoftstore.com/store/msusa/en_US/pdp/Office-365-Home/productID.286395000> Meanwhile, Home and Student is $140 and should last about 5 to 7 years before it become too old to use. At an optimistic 7 years, that's the same $20/year per machine as Office 365.   >Back to the "a", which is 5GHz and "g" which is 2.4GHz. >What if it's 802.11 b/g/n/ac ?   No such thing. In order to do "ac", it will need to also do "a". So the typical designation will be: 802.11 a/b/g/n/ac   -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558

I can buy a legit key for MS Office 2015 for 30.00 or so. Download it and use that key to activate. Always worked for me. I even bought keys for my surveillance camera use on Synology NAS. Real =AC mode, 80MHz wide is full -AC with 4 MIMO(4 antennas) and some will work on MU-MIMO(yet to come by Qualcom, Quantenna, etc.) You just specify dual band card as an option. Some HP laptops don't like any card. HP has white list of WiFi card.

Intel 802.11ac WLAN and Bluetooth(R) [1x1]   >Which of those is *both* 2.4GHz and 5GHz? >How do I know?   I would guess the number 3 will certainly do 5 GHz. However, the web designers truncated the letters that designate the all the protocols, listing only the highest (fastest) 802.11ac. Presumably, that would include all the lesser protocols, including 802.11 a/b/g/n. However, I can't be certain without knowing the Intel model number of the wireless card.   -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558

G, N, AC. If it is AC card or router AC is downward compatible with slower modes.Student version lacks some features and miscellaneous things. Why do you think it is cheaper? WiFi is 2 way street one laptop has AC card does not mean it'll be faster, corresponding device at the other end should be AC capable too. If AC card talks to N card speed will be that of N.

This one is dual band(2.4GHz, 5GHz) This is AMD cpu based laptop. A10 is the top end one. Video card... Rxxxx. xxxx at higher number is better one. Any more questions? Don't forget to read reviews on this model to see whether buyers are happy or not.

So, what does that tell us?   Are we saying the "ac" is both 2.4GHz & 5GHz by virtue of the "a" in "ac"?

The HP spec, as you have seen, just says "ac" for the high end card. http://i.imgur.com/hBcFWkQ.jpg

Not a school.   She only has an ancient WinXP desktop that has Office 2007 on it. When she gets a new laptop, she needs a new Office anyway.   1. Renting Office 365 for a laptop costs $100/year and can be put on 4 more non WinXP machines that don't actually exist. After 7 years, renting cost her $700 for Office for that one laptop, which is more than the laptop costs.   2. Buying Office 2013 costs her $140, and can be put on one desktop and one laptop. Since the desktop is WinXP, the additional license is moot, so, it costs her $140 for 7 years (or 10% less with the teacher discount).   It's a no brainer, to me; but this isn't the question in the OP, so it's just an offshoot discussion which isn't at all confusing to me.

Sure looks like National Semiconductor to me. My guess is the date is from the 90s based on the edge of the capacitor shown in the same photo - makes the date 1994 and 44th week.   It will be Silicon then and Ted's recent post in this thread gave a very good explanation on how to identify its parameters using an identical transistor.   The OP could tell us if there are other transistors using the 13903, but a different code beside the NS symbol - that would pretty much show that three digit number is the date code if it is something like 4xx, 3xx, or 5xx which would be a reasonable spread for date codes for a special run.   John :-#)# -- (Please post followups or tech inquiries to the USENET newsgroup) John's Jukes Ltd. 2343 Main St., Vancouver, BC, Canada V5T 3C9 (604)872-5757 or Fax 872-2010 (Pinballs, Jukes, Video Games) www.flippers.com "Old pinballers never die, they just flip out."
