Do I Have Two Bad Wireless Adatpers?

Gateway / Nv58 series

Specs: Microsoft Windows XP Home, 2.1 GHz / 4023 MB
Hi, I recently have been having problems
(which has progressively gotten worse) with my internet connection on my desktop computer. I would get limited connection and/or no connection. When I have connection it is generally slow; 1-11mbps and a low signal strength. The wireless card is a Linksys WMP54G wireless PCI adapter. So, I tried another PCI wireless adapter, the NetGear WG311v3 and it did the same thing. Now my Gateway NV5814u (Vista) laptop has a perfect connection speed and signal and it sits right next to my desktop. Do I have a two bad wireless PCI adapters for the desktop computer?

Thanks for the help!

Switch the WiFi Chanel because you are probably getting interference on it. You do this on the Router Configuration Page. Just type IPCONFIG at a command prompt and find out what your default gateway is and then type that IP address into a browser like I.E. or Firefox.

Okay, I got to where I can change the wireless channel.. there are several options (11 of them) ranging from 2.437GHz to 2.462GHz. Does it matter which one I choose and will it effect my other computers that are on my connection?

Thanks for the reply btw!

No, because most WiFi software is auto seeking which will pickup the new channel.

I usually use uncommon ones. Channels 1,6, and 11 are default on most routers so use something like 9 or 4 to get between them.

I recommend downloading inSSIDer
http://www.metageek.net/products/in...

It's a nice tool to visually see all the wireless signals and
which channels they are on. Try to pick a channel that is not
being used, if you can.

Also it has been my experience that upgrading to a wireless
N router has fixed a lot of my computer clients problems in
the past. Thats not to say the problem isn't with the wireless
adapters. Also there could be other interferences like
cordless phones.

Well changing the channel didn't improve anything. And I downloaded inSSIDer and only saw my network on there.. so I do not believe there is any interference. Would this assume then that I should upgrade my wireless card?

Thanks for the replies!

What was your signal strength indicated on the inssider? It should be something greater than -50dbmv. I would not buy another WiFi card unless it is a stronger one like around 1 WATT. You may have to look into a stronger Wireless Router.

The main issue here is that you are going through a floor with your WiFi and there is metal and wood which is reflecting some of the signal. You may have to move you desk to another location. This is one of the advantages to inssider is that you can start the program running then walk around with your laptop until you find the strongest signal.

Why would I suddenly have a problem with my desktop if the desktop was working fine a few months ago? It never moved and had a strong signal and then all of a sudden it doesn't.

Who knows. I have seen people suddenly have problems because their neighbor put up a HAM-Radio or they purchased a cordless phone set which used the same 2.4GHz. It could be something as simple as a construction sight through digging has changed the grounding properties of the ground around you. There are tools and software that will show you all of the signals on that frequency but they are not free.

If you chose to do WiFi this is what you have to live with. Personally, I used wired systems because they are more secure and no one can sniff my packets. This unfortunately requires you to do wall phishes unless you like pansduit on your walls.
