Interference on wifi connection?

DingDong · 21-09-2005 5:47pm #1

I'm having a problem with setting up a wifi network in my brothers house. I have the same setup im house and it works perfectly. I bought a 3com wireless router (3CRWE554G72T) from Komplett. when I used his router in my house it works perfectly. But when I use it in his house his laptop and home pc pick up the signal as excellent but the speeds seem to be more like dialup and it hops from 54Mbps to 1Mbps. I tried picking different channels on the router which didnt help. I not picking up any neighbours network or anything like that. I even tried turning off his cordless phone.
Anybody got any idea's ?

Thanks

Have you tried using your computer to connect to the router in his house?
Ensure line of sight when setting it up in house.
Sources of interference or disruption: any device using 2.4GHz~(This includes some bluetooth devices,cordless telephones, and microwaves) and walls,etc...
Check his laptop and PC for spyware/viruses,etc.

I connected a computer direct to the router and it works fine. His laptop is brand new and it works fine on my network. The laptop loses connection when i'm sitting next to the router. The only thing I can see different from my setup is I have the old firmware on mine.

Hmmm.Any neighbours taking advantage..?

Forgetting about the throughput to the Internet (that's a different can o' worms) - how frequently does the connection speed drop across the WLAN? Use iperf, and ping -t to test!
Please specify (Clearly) what clients are used for your machine(s) and his..

I had the same problem. Bad connectivity in my new house.

I have disabled WPA encryption (now my network is unprotected ..) and it's working better.

I have WPA on and off which made no difference. . The speeds seem to drop all the time even when it reading it at 54Mbps the speeds seem slow. I'm using just the inbuild xp software in the pc and laptop for the wifi connection. All the the pc's and laptop's are running XP.
Its driving me nuts at this stage.

... specify the wireless cards in use.
Specify what Service Pack is installed on the machines.
Disable power saving on the clients and on the router.
Failing this, reset the router.

Their all service pack 2. Not too sure the make of the card in the pc. But the laptop is a fujitsu siemans with an inbuilt card.
Thanks for the help Karoma I wont get a chance to have another to look at it,
heading off on hoildays tonight.
