We finally got around to sending our broken SRW248G4 back to Cisco, which they promptly replaced (well done ),
However, when i got it back, i decided to deploy the latest firmware - v18.104.22.168 from the Cisco downloads site, the upgrade went well but on starting up i am now no longer able to access the web UI config interface - i get the problems i previously had before applying the IE workaround bug. No amount of fiddling with IE settings and versions managed to make it work.
OK i thought, that firmware is broken, i'll downgrade. Downgraded with the console interface and TFTP - v1.2.2b - downgrade went well, however the web UI still doesn't work.
On our other identical switch v1.2.2b works fine so i can't understand what's wrong.
Anyone any ideas? I tried two firmwares and factory resets to no avail.
