Have you tried another Ethernet cable, or can you move the machine to a known good connection?<br><br>Do you see anything suspicious in your Console logs? Such as relating to DNS, etc.<br><br>Also you can try the the target disk mode suggestion. Boot your machine from another machine that is in target mode. If it runs fast from that HD you're sure it's not hardware. I doubt it is since actual d/l speeds are good but you never know if the Ethernet chip is getting confused.<br><br>Did you try reinstalling the latest combo update, the big sized one?<br><br>------>#1 - JD's Trivia game<br><br>------>#2 - MM-MCF Trivia game
Well this pus[i][/i]sy has used it more than once to fix anomalies.<br><br>I mean it's poly, right? Consider the source.<br><br>------>#1 - JD's Trivia game<br><br>------>#2 - MM-MCF Trivia game
I'm sitting here with a bit of a slow browser thinking maybe, just maybe, I should go back and do a combo update on the MBA and clear its chakras...<br><br>Naaah, you're still all a bunch of pu[/i]ssies. <br><br>[edit] is the censor becoming smarter? Shi[i]t.<br>
In my case I found a DNS server entry which I had somehow picked up years ago which stayed active until all of a sudden the long forgotten DNS server as referenced went off line and the DNS queries were suddenly taking ages to resolve.
System Preferences - Network - Advanced. DNS tab. Remove all unwanted DNS entries. Usually there should only be one entry in the list being your NAT router. If you are on a static address then it should be YOUR ISP DNS server not somebody elses.
Just one DNS server in the list which does not respond properly is enough to crawl the browser to become almost unusable.
Hope this helps eliminate at least one possible cause.
