Q: Imac (early 2008) constant wifi packet loss
I have an early 2008 imac (2.8ghz, 6GB ram, 128gb SSD card) running Mavericks 10.9.4. i'm having problems with wifi packet loss to my uverse wifi router (a Pace PLC 5031NV-030. If I ping 192.168.1.254, get dropped packets on the order of around 25% usually. I don't lose connection and it's not a wake from sleep issue, like I find all over the forums. It's just a poor connection that makes it unusable for skype/facetime/streaming video. Here's the thing, though, my iphone doesn't drop packets and neither does my wife's W7 laptop. And when I moved my imac into the room where the router is and hook it up via ethernet, no lost packets of course. So it's only on my imac and only when I use wifi.
I have tried the following
- Called uverse and gotten a brand new router. I plugged the new one in (using all new cables and power cords that came with it), exact same problem.
- moved the router physically to the other side of the room see if anything was interfering with it.
- changed the channel the router broadcasts on to an empty one i found using the wifi scan in apple's wireless diagnostics
- turned off our roku and any other device in the house using wifi
- changed wifi bands: 802.11n/b/g to b only to g only and n only
- changed the wifi security (on/off, wpa2 tkip/aes to wpa2 aes)
- reset p-ram and smc
- repaired permissions on the startup drive and checkdisk
- removed any wifi passwords stored in keychain access
- in System Preferences->Networks, made a new location, changed the wifi to be first in Service Order and rebooted
- removed /Library/Preferences/SystemConfiguration
- ran the kext utility that I saw on a thread about yosemite problems
And generally pulled my hair out. I've been searching these forums and the net for days and nights now. Any other ideas?
