I am still trying to figure this one out: Due to a quirky setup my DHCP server hands out the wrong = non-working gateway address, which means no Internet. Therefore I reconfigured the 2614 (fw 126.96.36.199) with a static IPv4 address and the correct gateway, but to no avail: Both ping and traceroute fail for Internet targets (tested with IPs, not hostnames).
Can anyone replicate that? I’d upgrade the firmware, but without Internet access… Ok, I may have to go for a local TFTP server until then. But how do I actually trigger a firmware upgrade on the phone/ the web UI?
EDIT: It appears that only a reboot can trigger a firmware check - clicking the “Provision” button in Maintenance --> Tools was not sufficient. Upgrading via local TFTP server to 188.8.131.52 worked, but the static IP/gateway issue remains: No Internet access.
BTW: The TFTP upgrade log showed some errors on the server, it appears the phone made several attempts. And as a side note, it was looking also for ring1.bin, ring2.bin und ring3.bin (which were not there).
