Several variables in the router's config can be tweaked but personally I haven't had much success with this.
The later RouterTech firmwares do have a memory optimisation script which can help (and which are scheduled with the crontab).
A simple batch and script file in combination with the Telnet Scripter ( viewtopic.php?t=282 ) can be used to temporarily 'unlock' or 'unblock' a router (your mileage may vary).
The script (needs router's IP address and password):
Code: Select all
HOST 192.168.1.1 23
WAIT "login"
SEND "root\n"
WAIT "password"
SEND "password\n"
WAIT "#"
SEND "/usr/local/bin/memopt.sh\n"
WAIT "#"
Code: Select all
ipconfig /release
ipconfig /renew
ts.exe /r:quick_opt.txt /o:quick_out.txt
