I have an xps 521 with the 1202 card and I have the same issue, no solutions yet, what router are you using?

Mine is working right now. Yes I changed my router, I was using the shaw provided Cisco router which combines the router and modem,  but now I switched it back and returned to the old modem and I bought the Linksys E2500 then the wireless seems works very well now. 

Do you know about the inssider software? It can check the channel overlapping in your community, which causes interference. If you don't here is the link: http://www.metageek.net/products/inssider/.

BTW, it is better if you can buy a router with dual band like linksys E2500, this router reduce the interference by providing both 2.4G and 5G bandwidth and our wireless card supports 5G.

I have the linksys ea6500 .. the card drops to limited connection on the n 5.8 and n 2.4

In this case, I guess you need either call your network company or alienware for your wireless card exchange.

Its not an isp issue. The laptop is the only thing that drops.

Elvis7,

Can you run Network Interface and post the results back here.

Rick

here is the log, I will run it again when the connection drops and changes to limited connection and post it here.

There is 1 interface on the system:

Elvis7,

I'm not sure about channels on wireless N routers. Usually the higher you can go, the smaller the antenna, the better the reception.

Try these tweaks....

Start, control panel, device manager. Click on Network and then right click on your wireless adapter, left click properties, power management. Uncheck the box, allow computer to turn off this device to save power.

Not sure if your adapter has these setings...

Click on advanced. Look and see if this adapter has antenna diversity. If it does, try changing Antenna Diversity from Auto to Aux.

Go to start > device manager > advanced > bandwidth capability > change to 20/40mhz

Go to the power options, and changed the Wireless Adapter Setting, from Maximum Power Setting to Maximum Performance.

Rick

that did not make a difference. Here is the log I made from when the connection dropped to limited.

btw, I have not moved from my previous log position, just changed the direction of the laptop...

2.4n is on channel 11. cordless phones are on 5.8hrtz  . no they are not the issue.

im always on 5.8 n ... but also get random limited connection on 2.4

Elvis7,

It looks the same except the connection mode went to profile.

Did you use some type of connection manager to connect and setup a profile?

Try changing the chasnnel in your wireless router to a channel between 52 and 64 and see if it improves.

Rick

I use the native windows 8 wifi manager. already tried different channels  and the 5,8 and 2.4...

Elvis7,

I still wonder about the cordless telephone causing the connection problems. I would watch this closely when the phone rings, is in use or the connection problem happens.

THIS ARTICLE states...

Some cordless phones advertised as 5.8 GHz actually transmit from base to phone on 5.8 GHz and transmit from phone to base on 2.4 GHz or 900 MHz, to conserve battery life inside the phone.

and

43–50 MHz cordless phones had a large installed base by the early 1990s, and featured shorter flexible antennas and automatic channel selection. Due to their popularity, an over crowding of the band led to an allocation of additional frequencies, thus manufacturers were able to sell models with 25 available channels instead of just 10 channels. Despite being less susceptible to interference, these models are no longer in production and are considered obsolete because these frequencies are easily heard on practically any radio scanner.

Rick

Elvis7,

On a wireless routers, in the g mode as people know it 2.4GHz the best channels are channels 1, 6 or 11. I find the best results are channel 11.

On a wireless N 5.0GHz, it seems different. I was trying to get the information from this article.  List of WLAN channels

The article states about using DFS/TPC for less interference. I tried to select channels with all green blocks.

Questioon is there a cordless phone in your home? If yes, when the phone rings, or you use the phone, you get disconnected?
