Hi, my Linksys BEFW11S4 wireless cable router has only recently started causing problems. Firstly, I have the random LAN lock fault (poss ID'd as DHCP fault that Linksys won;t fix - have read that here or somewhere). PC has LAN connection but cannot browse/connect to anything - reboot router all OK - it's as if the LAN just disappears - WAN on BTO router side is fine. Upgraded F/W from v1.50.14 to v1.52.02 improved but caused VPN fault below. Secondly, using upgraded F/W v1.52.02 to fix above I sometimes cannot use VPN to connect to secure work connection for remote working. Regress back to v1.50.14 VPN works, but back with LAN issue again. Any suggestions would be appreciated - thanks in advance JonMaC - UK SE england Current setup: BTOpenworld Business 1Meg > EN5861/Siemens SB5830 > BEFW11S4 > workstations x 3.
