hi there, i've got a netgear mr814 wireless rounter connected to a netgear dg814 modem/router. i've got a G4 (hard wired) and a macbook wireless connected
all seems fine except for when we use the macbook wirelessly -- especially the odd site (banking, online ordering) that requires that forms be submitted. the browser will usually timeout and i can't get any reliability. if i try the same site with the hardwired g4 all works fine.
i've been through the settings on the modem and wireless router and i think all is good there, so can't work out the problem.
Sounds similar to a problem I've had when setting up a block of Static IPs. So may be a long shot but could be worth a try:
Try changing the MTU Timing on the MacBook to 1492 (rather than 1500 which I think should be default).
