Wireless Router Issues
There are some wireless routers known to have problems with Linux. This section contains workarounds.
Linksys RV016
At some point after kernel 2.6.13 there was a change that causes this router not to function correctly under Linux.
Issue
When not connected through a firewall the system operates correctly. However when connected to a firewall local access works but internet connections begin and fail to continue past a certain point. In a given example, a wget fails after downloading exactly 5,463 bytes.
Solution
The workaround can be tested by opening a terminal and typing:
echo 0 > /proc/sys/net/ipv4/tcp_window_scaling
To make the change permanent, open a terminal and type:
gksudo /etc/sysctl.conf
Add the following line to the file
net.ipv4.tcp_window_scaling = 0
More information is available firewallvpn__linux here and here.
