Hello all,

Well, my account has been upgraded from 500Mb to 1Gb. Level 2 action was required to get the phone working.

I have the router in modem mode.

I am unable to talk to the modem via 192.168.100.1, has the modem address changed?

Samknows, doesn't believe in the router (in modem mode) is this anticipated behaviour?

I am also obtaining quite low speedtests both from the router (Unifi USG) and from local devices (ethernet connected via gigabit switches). Is this likely to improve?

The account is showing "Gig1 Fibre Broadband", I appear to be obtaining under 200mb/sec.

Until I can see what the modem thinks is going on, I'm running with less than 20 20 vision, so the actual address of the modem would be useful. Thanks in advance.

Regards,

Francis,.

http://192.168.100.1 is correct.

Can you turn off the HUB, unplug from your router, and plug directly into an ethernet enabled device.

Turn the HUB back on and:

• Complete a speed test.
• See if you can connect to the HUB.

Thank you,

Well ... So I am plugged in  to the top port on the modem.

I can connect to the hub ... but not for long. After a few seconds it logs out and attempts to log back in are met with "Someone else is currently logged into the settings page. Only one session at a time is allowed. Please try again later."

And  Later ...

"The connection has timed out, The server at 192.168.100.1 is taking too long to respond."

Speedtests are slightly lower. Sam still doesn't know about the router.

There is a 6db filter present from the Hub3 days, the 3rd from the top error is interesting.

Well ...

It's settled down now.

However we appear to have avariable path to the modem.

15? minutes later nothing changed ...

[carl_pearce]

That is odd.

Are you still using the HUB in modem mode directly plugged into a device?

[Tudor]

I believe the 10.x.x.x address is of the VM CMTS on their internal network. Have seen these 10.x.x.x addresses before in trace routes.

[armstrongfj]

Carl,

I was for those two tracert's

I'm back on the modem/router now. I was able to get half a page of the modem screen before it froze. If I were suspicious, I'd say the modem is flippflopping between two states, sometimes it has a word, sometimes 10.250.64.1 is the respondee, for the most part 10.250.64.1 wins. I think it is static.virginmediabusiness.co.uk, probably the default router for the modem. In my view the modem should deal with the address and not hand it off to the next router in the chain. So I'm suspecting misconfigured service or DOA router.

Regards,

Francis

Likely a bug I take it this is with a PC to the hub in modem when you get that result?

I never though of this but with my SH1 in modem mode with a PC doing a tracing route to 192.168.100.1 should it not with TTL 1 ping back 192.168.100.1 and VM 10. network at the same time? Which it don't so maybe my SH1 does not forward the TTL 1 ping on to 10.....whats odd about your tracing route is 10. replied first then 192.168.100.1 you would think it be the other way round....so likely the hub is being slow and does not reply fast enough and 10. wins!

It's a known bug if you have hub 4 in modem mode and 192.168.100.1 comes unavailable after sometime, rebooting solves it for now.
