I have a Draytek Vigor 2820n (about 12month old) - recently, after a period of time (usually 12 hours plus after restarting the unit) I find I am unable to access the web admin pages for the router via its IP address.
So normally I put in 192.168.9.1 into my browser and the router admin page login comes up - I login and away I go. But when this 'fault' develops typing 192.168.9.1 takes me to a search page for '192.168.9.1' on google.
At first I put this down to a fault with the unit and have RMA'd it once but the fault persists.
Also I have now tried my spare Vigor 2800 and that is now doing the same - so this does not appear to be a problem with the router (unless they have both developed the same fault).
I have 5 or 6 clients who use the draytek 2820n and I've not seen this problem before.
IPCONFIG /ALL says that the DHCP, DNS, Gateway addresses are correct (192.168.9.1).
This problem occurs on all PCs on the network.
The problem occurs regardless of browser (tried IE8 and Firefox 3.6)
Restarting the unit cures the problem.
Internet access from network PCs via the router is unaffected.
I can ping the unit no problem.
I have disconnected all PCs from the network and connected a single laptop - problem remains.
Restarting the unit fixes the problem.
Other info which may or not be relevant.
I've moved premises recently (and ISP) - this problem only seems to have occurred since the move (would seem this is relevant - but don't see how). Computer equipment connected to the router is pretty much the same.
The unit drops the line (usually at least once a day), automatically restablishes, time of line drop does not seem to coincide the fault described above occuring. The reliability of the line is something I can't look at until I can reliably look at the web admin pages.
So - what is causing this and how do I fix it ?
