For a while Skype was decent enough and recently it's declined to the point not being usuable. Looking at the call details my dl varies anywhere from about 1k-5k. The upload is anywhere from maybe 3k -100k. A week ago the dl & ul was reversed.
What I know:
latest skype client
my DL = 25M, UL = 5-6M, ping <10ms, 0% packet loss. line quality A according to pingtest.net
other person - DL = 2.2m, UL = 1M, forget ping but low, 0% packet loss. line quality A
latest webcam drivers
tried 2 pcs, same thing
bypassed router, same thing
relays were up 4 yesterday but when dropped down to 0 no difference
both firewalls allow skype
It's strange because it can literally change from minute to minute but it's mostly just very poor.
