Lately i have been having some strange problems with my home and university accomodation wireless networks. I.e. both are constantly (by which i mean every 30 seconds or so average) disconnecting from my MBP (its the Rev A 2.16GHz 2GB ram with Leopard now installed (clean install). As you can imagine this is VERY annoying, I thought at first it was just my IM client that was at fault, but then i tried MSN iChat Adium and Meebo.com on the internet. But now i have realised my wireless is disconnecting very briefly, very often but it's hardly noticable unless you watch the Airport icon. Are there any known firmware or software related problems with airport or other related components due to leopard? Or are there any checks i can do via utilities already installed or other applications etc etc? Any help would be greatly appreciated! Thank you in advance! p.s. both wireless routers are different makes, at home i have a 2 month old netgear and at uni it's a speedtouch.
