Replying to [comment:2 anonymous]:
How do I set mssfix? I googled it and just see it's some iptables rule.
So I will reiterate.
75Mbit/75Mbit fiber NO PPPOE, just ethernet. Testing w qos off, does
80/80 max.
Run a download, works fine- getting at least 70 mbit with qos, or more
without.
BUT when I upload at 35mbit,50mbit, or full upload speed (~75mbit) the
download crawls down below 8mbit.
CPU is not maxed out according to htop in SSH. Ping google.com -t is
consistently 10 ms or so, not a latency issue.
This happens whether qos is on or off. It happens on AA, trunk, or custom
builds, but NOT stock netgear firmware. I tried manually setting the WAN
port to 100 full duplex, but that was even worse.
Also, my buffalo g300nh with qos on OR off, does not have this problem
with AA, trunk, or gargoyle (based on AA). It has a much weaker CPU, and
is maxing out cpu! You would think that would be the one to slow upload
to a crawl!
