if you have a router put the super hub into modem mode and all your problems will go away
log into the hub - 192.168.0.1 from any browser - enter name - admin and password - changeme
on the left is a column - look for modem mode - tick that - save and log out
connect your router to the lan port next to the coax on the super hub - turn off the super hub and pc - power up super hub wait for all lights to come on - power up router and then pc - you should be connected to internet
set up wifi as you need
if you want to log back into super hub [in modem mode] its 192.168.100.1 name/password as before
Sorry to hear the issues your facing with the superhub.
We are aware there are some wireless problems with the superhub and are currently beta testing a new firmware update which should solve a lot of problems. Once this has been tested it will be rolled out to everyone.
I have been having problems with wifi for 3 months -dropping signal etc and finally phoned virgin media to see about moving to another provider. They told me that they would send out a superhub with an installer and all would be well. Spent last 4 days - 4 hrs per day trying to resolve problems with wireless signal - really poor - in room with laptop only 4 bars for signal. Leave room and goes down to 3. Move downstairs and lose signal completely.
Have done all the problemsolving stuff - reboot, changing channels. Their tech dept said they would send out a wireless adapter dongle for my laptop - but dont see how that will work.
I sorted out my mother in Law's package and she is due to get superhub on Thursday but I really am frustrated at this stage and if it cant be sorted want to move provider for both her and us.
Think Virgin have been Disingenuous - should have told us about the wifi problem and offered some solutions rather than having people waste so much time on them????
try different channels - alter mode to 145 - look at security - some is better than others - turn off firewall - all will help - you say you have tried all those
the new firmware may help as and when - but the wifi [at the moment] is not great - put it into modem mode and add your own router - costs money - solves the problem - not what people want to hear or want to do but as i say it WILL work
Only just found this topic so hope I'm not too late with the suggestion that seems to solve the problem, well after 3 days of problems and since then I have also actually emulated the problem which does then re-occur with the super hub.
What I have discovered is that the wifi problem only seems to come about after the router has been turned off at the mains, but what I discovered is that if you then use the super hubs console to restart the modem it's as if it then detects my equipment better than just turning it back on then spending days with all the tests telling me there is 'no problem' when clearly when something is NOT WORKING when it's supposed to be working IS A PROBLEM.
Although plugging our routers back in and bypassing the modems router as suggested earlier seems the easiest solution.
Welcome to the wonderful world of the VM Superdub (my nickname for it).
The superdub features do not work correctly, (like Wireless, it reboots its self, resets to factory defaults
by itself, and many more), so a good work around is put the superdub into modemmode, and add an external
router (you need to buy an external router if you dont already own one).
No matter how many firmware updates there are for the superdub. R30 was the best, as it gave it modem mode.The best feature, and only way the superdub works.
I work and game on PC (wired), PS3 (wireless), and Xbox (wireless) in modemmode config via ASUS RT-N66U
router,on the VM 100Mbs service and get 103MBs Down and 9.45Mbs Up.
The ASUS RT-N66U uses BOTH Wireless signal 2.4Ghz and 5Ghz gets to the whole house / garden.
-- Red (VM SH2 AC Beta tester) Running on 200Mb VM service with SH2 AC in Modem Mode, with a ASUS RT-N66U router. With this setup I get Fantastic WIRED and WIRELESS Signals in my home. I dont work for VM. But I work in IT, and I know my tech. My advice is at your own risk.
