superhub 2 hard reset problem
 
Hi Guys n gals

Been happily running my shub 2 in modem mode routing through a Linksys E3200 for nearly a year until i terminally lost connection and the occasional router/shub off/on soft reset for random disconnections didn't work.

I tried to use an ethernet cable from the active ethernet port to access the modem config page but this didn't work either (still no connection). Decided to do a hard (paperclip) reset but the thing rebooted back into modem mode again, i thought that a factory restore would put it back into router mode ??.

Rang 151 (Friday night so waited ages to speak to someone on the other side of the world) who did manage to re-set it to router mode.

I'm wondering if the router is faulty, it works OK (ish) in router mode but my son gets lots of disconnections on his X-box one with the shub2 which he never had with the linksys so i really want to be able to put the vm router into modem mode again to test if the linksys is definitely faulty or maybe another router withgout worrying about being able to restore the router capability if i need to.

Also when in modem mode i thought the power button was supposed to turn purple, it doesn't it stays blue.

So in a nutshell the shub doesn't hard reset back to router mode and in modem mode the active ethernet port seems to have stopped working.

Any thoughts gratefully received (General Maximus are you there :confused:).

Cheers all.

Sometimes you need to do a bit more than a pinhole reset. You'll need to hold the pinhole down for a good 30s, then power off the device (while still holding down the pinhole!) for another few seconds, then power it back on (again, while keeping the pinhole depressed!). This should reset it. If it's not resetting this way, it's faulty.

Virgin's modems (and this includes the hubs in modem mode) are quite finnicky about swapping devices around on them. IF you just unplug one device, then plug another in, it will not work. At the very least you have to power off the modem (hub) to get it to allocate an IP.

The reasoning is somewhat convoluted, but the short version is that your modem only expects to have one device plugged into it at a time, when you plug a second device (even without the first connected, even into the correct port), it will refuse to speak to it and that device won't get a connection.

Sometimes, very occasionally, even switching the modem off and on with the new device connected won't result in a connection. To force this to work, there's a special procedure you must follow.

Step 1): Remove/unscrew the white coax from your hub
Step 2): Power off the hub
Step 3): Connect your new device
Step 4): Power the hub on (WITHOUT the coax connected)
Step 5): Wait.

Now after a few mins of your hub trying to get an internet connection, it will give up and just allocated your machine an internal IP (192.x.x.x).

Side note: If you're struggling to access your hub/modem and it's stuck in modem mode, you can use this technique at this point to gain access to the hub configuration page and switch it back to router mode. The alternative is to statically set an IP on your machine of something like 192.168.0.5 and that should be enough, however if you're not comfortable with doing that, this method works fine.

Once your machine has received it's 192.x.x.x IP, it's time to continue.

Step 6): Screw the coax cable back in (DO NOT POWER OFF THE HUB!).
Step 7): Wait.

This does some fancy shenanigans with Virgin's UBR, which should force it to allocate you a correct IP and allow this device to go online. You might need to quickly reboot your hub one more time, but this is mostly to force your device to pick up the new IP. You should now be online.

Wow, thanks for the speedy and informative reply Kushan, i'll be printing and keeping it for future reference. ;)

how sweet, somebody misses me :hugs:

Kush is right about the reset, it needs a good 30 secs. It defaults back to router mode and from there you can go to http://192.168.0.1 and put it back into modem mode. Bear in mind that you might have to reboot your Linksys because if it is still connected it will have received a local address such 192.168.0.2 on its wan port and for you to get out to the internet it will need a proper VM ip once the shub has rebooted. Tbh I would let the shub reboot and do it's stuff and then I would reboot the Linksys next. If you are using a direct connection to the shub to access the gui and bypassing the Linksys then you'll have to do an ipconfig /release /renew as you move the cable back and forth.

Bed time :sleeping:

aha ipconfig/release and renew...doh i didn't think of that in my blind panic due to kids giving me grief.

Cheers GM :waving:
