Nighthawk 7800 & Virgin Superhub 3
Hi all, I've had this issue now since I hooked up the Nighthawk and I was wondering if anyone has experienced the same issue. I have the Virgin Media superhub 3 (which is in modem mode) connec...
I understand SHv3 is device leased by VM and manufactured by Arris.
#1. when the device is in Modem modem, please make ONLY and ONLY R7800 is attached to it since Virgin Media would set MAX_CPE=1 in the DOCSIS config file (I assume you are already doing this)
#2. you need to figure out, whether modem DHCP lease is expiring or Router's WAN IP DHCP lease is expiring.
#3. you mentioned wired devices have internet access but wireless do not. You may want to check ping and traceroute on wired and wireless devices when this happens to see and compare both the responses.
#4. Alternatively, you can try setting NightHawk in AP mode (not desirable) but atleast see if you can run beyond 7 days.
btw, this is Cable Modem Forum, you may want to post on Router forum as well.
Thank you for your reply.

Yes. I can confirm that only the router is connected to the SHv3. Only one port is active on the SHv3 hub when it is in modem mode.

I believe it is the Router's WAN IP DHCP lease that is expiring. Is there a way to extend this?

I'll look into this on Wednesday when the lease renews :-\

I've considered this but like you say its not disirable.
It sounds like you might be right in saying it might be the routers wan thats lease is expiring. Do you know how to extend this time?
Lease time is decided by Virgin Media as they are the one who issued the DHCP IP.
router cannot increase the lease. when the T1/T2 timer expires, Router is supposed to renew the lease.
- Hi thank you for your reply.
The router does renew the lease automatically but after it renews access to the Internet is not fully restored. WiFi connected devices have no Internet access but the wired devices do.
Possibly a faulty router?If only WIFI devices loose internet access after period, then it looks like a SW bug most likely. I am not from the router group but I can check with someone if you are interested in debugging this problem. Let me know. I dont control router group activities and priorities but I can certainly ask.
