Snow Leopard Wifi Issues

Hi,

I have a Macbook Pro 2007 2.4 and i just upgraded to snowleopard from tiger (which is worked perfectly after updates) and now i cannot get a wireless connection, i sometimes get it intermittently but not very often. I did a clean install, and when it asked me to connect to a network it did but after i updated the software it out right refuses to connect, it can see the SSID but i get "connection timed out". Our router is currently on a WEP password and i know that this might be the problem but out router does not support WPA very well. I know its not a router issue because i have 4 other PC on it working fine. I have tried deleting internet pref's cleared DNS cache etc, but no success. Is anyone else with a 2007 MBP having these issues?

Any help would be appreciated.

Thanks

Matt

I'm using a MBP3,1 (nov 07) with Snow Leopard and not have any issue during normal operation. Do you know what the temperature is when this occurs? An odd question but the only time I have had a drop out is when it's very hot.

Its not a temperature thing its just all the time, SMC Fancontrol show 41c, i had the same problem with Leopard when it first came out. Very frustrating !

Right, I changed my router to WPA and still not joy I, still connects in tiger though so its SL.

I've found the wifi to be very dodgy on Snow Leopard. It'll connect most of the time, but then will randomly disconnect (or appear connected still, but doesn't actually seem to be able to send/receive data) and I'll have to turn it off and back on again in order to connect. The other laptop on at the same time running Vista doesn't have this problem so I know it's not a router issue.

I've just gone from Tiger to Snow Leopard on my MBP and no WiFi issues at all. Though I put in a brand new 500GB 7200RPM hard drive so got a completely clean install (I've never trusted upgrade installations).

Any WiFi problems I'd always suggest going back to basics: No encryption and no MAC filtering etc. If that doesn't work change SSID and channel and try again.
