I've bought a new iMac, and it shipped with Lion. It seems to drop out quite frequently, perhaps more often than my early 2008 MBP (which now has lion also). Is there any way I can figure out if it's a Lion bug or if it's an iMac issue? My home network is fine, so it's not that. To be more specific on the drop outs: while I'm browsing, or even when I'm not browsing, the internet cuts out. Wifi still reads it as full signal, but pages just hang. Often if I run a "ping" with Network Utilities it fixes it, but to sure-fire way to fix it is just turn wifi off and on again - that fixes it very quickly.
