Hello,
I will answer as best I can.
- I have four devices connected wirelessly and three devices connected wired. Not all devices are on at the same time.
- Factory reset has been performed, yes.
- Factory reset was performed after the firmware update.
- This issue was occurring prior to the firmware update as well. I've had the modem for 2 months. Despite poor wireless performance, the modem performed without issue during this time.
- MTU was double checked with ISP and was correctly set to 1492 in the modem settings.
- Under PPPoE, "Always On" was enabled.
- SSID was changed to a custom name.
- I enabled both 2.4Ghz and 5Ghz, mixed on both. On a side note, prior to this problem occurring, I would witness random dropped pings when pinging 192.168.1.1 continuously, via both 2.4 and 5Ghz wireless connection. When the problem started and the modem would disconnect, I experienced little to no dropped pings.
- Channel width was set to Auto.
- Channel was set to 5 for 2.4Ghz. 5Ghz was left at default.
- Security mode was set to WPA2 for both frequencies.
- No cordless house phones, I have naked DSL. No phones apart from my iPhone. No back to base alarms.
- Plenty of wifi routers in the area, annoyingly - I'm not convinced this is related to my wireless connections though. Firstly, the wireless connectivity remains unchanged (or gets better) after the modem disconnects and secondly, I witnessed the disconnection when wifi was off as well.
- The advanced wireless settings were unchanged apart from the frequency strength which I set to 'low' on both frequencies.
I'd like to know what is actually happening to result in the following messages, or simply an explanation into what these messages mean. I googled and found related information here and there but nothing to solidify my understanding. What is the dnsmasq, SIGTERM? Why would dnsmasq exit and from what? What does it mean that no upstream servers are configured? I presume that whatever the dnsmasq is doing is resulting the the PPP connection to be terminated?
