problems with my wireless connection! please help!

hi folks...
got my Dell XPS 1530 a couple of weeks ago, and am experiencing some problems staying online!
it seems the wireless connectiom randomly disconnects, just to reconnect again some 30 sec later!
really annoying!
my roomate is not experiencing the same problems on his computer, so i know there is no problems with the router or the network itself...

driver:

Intel(R) PRO/Wireless 3945ABG Network Connection


tried to download the driver and reinstall it, but doesn't seem to help! any bright minds that can help me out!?

 

Try to change the WiFi channel so your friend doesn't interfer with you.

 

i have tried this aswell, changing the channel multiple times, have tried a number of different channels! after changing channel, the connection improves, but still randomly disconnects! the positive side is that it seems to stay online for longer periods of time on the "new" channels (not the original channel).
do i just need to try diff channels until i find one which works perfectly, or could there be another problem causing the disconnection?
btw thanks!

 

How aggressive is the roaming function on your wireless card? If it's set for aggressive roaming, it may be jumping ship for another router signal that has fluctuating strength so that from time to time it grabs the attention of your wireless card.

 

There was someone else in the NBR having a similar problem, and the interference was caused by a cordeless phone working in the same band, the bad news is that cordeless using DSS of FHSS change the channels constantly to avoid eavesdropper and as part of the spreading process, so changing channels won't help much, but you can try. The solution is to change the cordeless for one in another band (e.g. 900MHz).

 

have your roommate turn off his wifi or check it out when he's not there

yes, in fact, microwaves, cordless phones, some security systems using wifi devices, etc., can cause a great deal of interference....

are you in a apartment, dorm, frat? Are there other wifi networks, or other laptop users?

and shyster is right about your card settings.... did you change any of them??

if you can, try raising the router up a few feet to see if that will help.....

 

Thats a very good tip nobscot6, u don't really think about it or maybe u might but never really do it but that does help alot...i figured that out yesterday...literally! :yes:

 

1. Switch off any cordless devices and leave only the router on.
2. Make sure the FOV between your router and laptop is clear (for testing purposes only).
3. Connect them and run a bandwidth test using Aida or something else.
4. If connection keeps on dropping change the channel and encryption. For example my NETGEAR has WPA+TKIP&WPA2+AES at the same time. I noticed that one of my computers kept dropping the link on WPA2+AES and ran for weeks with WPA+TKIP. So I left the latter on that pc.
5. Turn off QOS
6. Check roaming of the adapter.
7. Roll back/restore your driver.
8. Update your router.
9. Use the INTEL utility to connect and not the Windows one. I have the same card in my Amilo and it works better with INTEL than Windows.
10. Fresh OS install.
