Wireless cards...standards or what?

I use my laptop to connect to the wireless connection we have at work. No problems here, I see about 12 wireless networks available, but I need only one, ours.

Recently I bought a PCI wireless card for my PC that I plan to use instead of my laptop.
The problem is that suddenly I see only about 4 of those networks, and most annoying, not the one I need. The new wireless card is working though, I can even connect perfectly to one of those still available.
BTW, with the laptop I can still see the other wireless networks, including the one I need.

I don't think is about drivers, I tried the card on a windows PC with the drivers included on the CD, still no go.

I suppose you already figured out what is my question...are there any standards/compatibility features I consider before buying a wireless card?
What should I look for to make sure I see every network available?

Thanks

Moved this to the help section since I cannot come up with anything intelligent about it. And I know that our gurus can!

I would try using an extension cable for the aerial or physically rotating the case and see if that makes a difference - if the aerial is at the back and the router you are trying to connect to is in front of the box then the box could be blocking the signal. A USB wireless adapter may be better especially if is one that comes with a stand on a USB cable.

I agree with Joste!
try an extension cable this may solve the problem for you

Well, it has already an aerial connected through a 1 meter cable and the signal is very strong...the router is in the next room.

Anyway, I found some simplified info for dummies like me. :) http://compnetworking.about.com/cs/wire ... andard.htm
Now that I know what to look for I see that my laptop is using a (Atheros) chipset with 802.11a/b/g standards, while the PC is using a (Ralink) chipset with 802.11g only standard.

From the info above I see that b and g standards are compatible with each other, so maybe my network at work is using the a standard?

I'll see tomorrow. :think:

Thanks

PS, sorry for using the wrong forum section.

Ah, the problem is solved without me even lifting a finger. 8-)
It just happens that the old router was changed yesterday and now I can see the needed network.

I still don't know what was the cause (some networks still don't show) but who cares, I have what I need.

Cheers everyone :coffee_smile:

I had a similar problem and was with an 802.1 B Standard NIC. Linux or MS had the same screwed up issues.
The problem was worse with 802.1 A type routers. 802.1B is supposed to be compatible with A and B Routers.

I think when they came with 802.1 N and up it fixed the issue.
