Unusably slow wifi on new B+ and Edimax EW-7811UN
Posted: Sat Aug 22, 2015 7:42 pm
Hello all,
I'm having some big trouble with the wifi speeds on my RPi. Clean install of raspbian, and was able to connect to my home network. The internet works, but I'm seeing speeds of 1-3kb/s... I can google around and view pages but only at dial up speeds. I also have a NAS plugged into the router that I can see/access/view, but copying 10 20mb files resulted in 8/10 failing. Currently it's sitting 3' from the router without any improvement. Nothing else plugged in besides the dongle and a USB keyboard. Router is an Apple Airport Extreme (2014). In there I can see it connected at -50dBm with a 19Mb/s data rate on b/g/n, so signal should be fine. Went through most of the scripts out there online to change the power & sleep settings on it.
Basically it feels like an interference-type problem as I can ping websites and browse my local NAS, just slowly. Trying wget to grab a file to speedtest times out. If I do plug in an ethernet cable, internet is fine/fast. Help? Running out of ideas to check before just throwing the dongle away and buying a different brand.
Here's the config:
