Hi
I have a belkin wireless g router and am having problems with my connection constantly dropping out. I am using an acer aspire 5735 laptop running windows vista. My room mates do not have the same problem and their connection remains steady and so does my xbox in the same room. Its driving me nuts. Any help would be greatly appreciated.

Thanks

Make sure you have the latest wireless driver; if it is an integrated adapter get the driver from Acer's web site.

Please attach a screen shot of the Networks page of the Xirrus Wi-Fi Inspector.

Thanks for answering
My wireless driver is up to date. i am using an Intel(R) wifi link 5100 AGN

It will not let me paste a screenshot but here are the statistics it gives
ssid: 69Beacon2
Signal (dBm): -33 full strength green bar
Network Mode: 802.11g
Default Encryption: TKIP
Default Auth: WPA2/PSK
Vendor: Belkin
BSSID: 00:17:3F:15:67:8B

Further points to add i can connect with a stable connection if i am wired directly to the router

what error message do you get when you try to load the screen shot -
It maybe you need to reduce the size of the image when you save as jpg try and reduce the quality slightly

To post a screen shot of the active window, hold the Alt key and press the PrtScn key. Open the Windows PAINT application and Paste the screen shot. You can then use PAINT to trim to suit, and save it as a JPG format file.
To upload it to the forum, open the full reply window and use the Manage Attachments button to upload it here.
its quite important to see the network environment - how many other networks there are , strength and channels in use - to see if this is interference that is the issue causing disconnection.

also post here an ipconfig /all and three ping tests when its working OK and then repeat ALL the tests when it disconnects and post the results here

------------------------------------------------------------------------
{ipconfig /all}
If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post results here
We would like to see the results from ipconfig /all post back the results here
-> Start
-> (XP - enter the following in the RUN box)
cmd /k ipconfig /all
-> (Vista or Windows 7 - enter the following in the Search box)
cmd /k ipconfig /all

A black box will appear on the screen -
rightclick in the box
select all
enter
control key + C key - to copy

then reply here and
control key + V to paste
------------------------------------------------------------------------
{Ping Tests}
If you cannot access the internet with this PC, then you will need to paste the results into something like notepad and then copy onto a machine that can access the internet and post results here

Ping {plus the number thats shown against the default gateway shown in above ipconfig /all}

wow thats a busy environment
you have another strong channel on 6 - 1,6&11 do not interfere or overlap

what country are you in , if europe you may be able to change the channel to 13 , otherwise see what advice TerryNet has for a channel change in this environment - can we see ALL the networks from that image ?

when it disconnects - if you post all those results again should help us diagnose issues

OK , as your in UK it maybe a change to channel 13 would be worth while - BUT lets wait and see the tests on disconnect and TerryNets comments - as it may NOT be interference

I agree. In that environment channel 13 should give the best results. But the environment can change as people plug in their routers or change channels themselves, so another Xirrus output when you have difficulty is important.

The attachment shows channel overlap (overlap = possible interference). It applies to n as well as b/g, and the semi-circles for channels 12 and 13 just go on the right side like all the others. The goal is to choose a channel that has no overlap; impossible in your environment so the revised goal is to minimize the overlap. And overlap with weak channels is preferable to overlap with medium or strong channels.
