Dropping Internet (WiFi)
Posted: Thu Mar 18, 2021 4:32 pm
I'm not convinced that this is the router's fault but tearing my hair out and would appreciate any ideas...
Previous setup was Billion 7800DXL on ADSL2+ line, using both WiFi bands for around 20 clients and linked on 2.4G with a TP-Link TL-WA830RE to a small remote wired network. Worked stably at 11/1MBs.
Then the ISP 'upgraded' me to fibre FTTC. To smooth the transfer, I fitted their supplied Technicolor TG588v to the line and ethernet linked it to the 7800DXL. TG588v handled DHCP, 7800DXL the wireless. Started seeing the DNS dropping out, so connected devices report 'no internet'. Internal connections also failed, so I assumed that the DHCP was being confused somehow, possibly by the way I had connected the two modem routers.
After migration, the Technicolor came out and a Billion 8800AXLR2 went in, handling the VDSL2 line and both wifi bands. The 7800DXL was redeployed to act as range extender linking to the 8800 on 5GHz, serving the remote wired network and also 'repeated' 5G and 2.4G access points.
Having problems with the DNS still. Curiously, my Android has also stopped 'dropping' the wifi connection when out of range. Today, it still showed connection to my home network AP whilst 25 miles away. Rebooting the phone wifi unlocked that, and it connected to another AP correctly. On returning home, it picked up the home AP but showed 'no internet'. Again, rebooting the phone's wifi connected to the internet correctly.
Although I observed this behaviour on my phone, my wife's phone and laptop behave the same, as does my laptop; occasionally dropping the DNS randomly but always failing to pick it up when reconnecting. Once connected, the VDSL2 line runs properly at 40/5MBs (indeed the router stats show a stable connection with no resyncs).
All DHCP servers are disabled except for the 8800AXLR2.
All devices are 'static' IPs allocated by the 8800.
I think I've disabled the IPv6 allocation system.
Any ideas as to what I can try?
Thanks
John
