Linksys WRT54GL Router: Firmwares, Improving Performance, Overcloking, Slow speed download L2TP/PPTP UFI NGN

Low Download Speeds over L2TP/PPTP connections

Unfortunately this router is useless for UFI L2TP/PPTP connections which are in Israel.

Maximum speed was obtained around >750kBytes/s, which is not depend on firmware used (Tomato, dd-wrt, original) or overclocking at 250MHz.

EDIT: My solution now is Atom based motherboard from Zotac with WiFi card as my router/server. Power consuption is around 20-30W.

SO, STAY AWAY FROM WRT54GL ROUTER for >6Mbit over L2TP/PPTP. You will download maximum at 750kByte/s

Stick to 225, 240, 250 MHz. There reports of bricks on other clocks.
