[ale] Dropped Packets on Wifi

[Jeremy T. Bouse]

    Check /proc/sys/net/ipv4/tcp_ecn and see if it has 0 or 1... If it's 
1 then try echoing '0' into it and try again. Another check might be to 
see if you can do pings and DNS lookups which use ICMP and UDP. I had an 
issue like this when visiting family and bought them a cable/DSL router 
only to find that the mfg had botched their firmware to ignore the 
TCP-ECN bit if they didn't handle that feature.
