3com ADSL router slow for wirless web surfing

[ghosking]

Hi - I have been using 3com routers for years, recently I bought a new one a 3com Office Connect ADSL Wireless 108 Mbps Firewall Router - model 3CRWDR200A-75 and have the following very odd problem: -

It's working fine for internet access for all computers that are connected via Ethernet cable (wired), but for clients that are connecting wireless-ly there is a 20 to 30 second delay getting from one website to another - e.g from 3com.com to cnn.com. Once the website has been reached then it works well on that website until you try and surf to another site. It's some kind of routing/dns issue, but clients that are wired are not affected (same dhcp server which is an internal windows small business server). All clients that use wifi are connecting via new Cisco Linksys 54g PCI wireless cards, all of these are showing a minimum of 75% signal strength, some even show 100% (still same slow result). I have WPA security on, mac address filtering off. Any ideas what could cause this? All clients XP SP2 + patches.

Any ideas or help very appreciated

Hi,

I think the first thing to try which would be an easy test would be to use another Wireless Adapter, like a USB one? Make sure you either remove the PCI device or simply disable it first though for an accurate test.

Let us know if you get the same with the USB Adapater.

Thanks.

Maybe try your wireless FW without any security settings.

To rule out the security of WIFI, you could take 1 wireless computer and isolate it off your main network without any security on it or the client then see if it continues.

If it is a new FW I am assuming you the old one still so you could put all your LAN users back on it for testing.

Hi - thanks for the responses, the solution came from 3com (after a lot of hassle), a fireware upgrade - this resolved all the issues, and the router has been up for some time now without any issues

thanks
