Has anyone here been having issues with DNS lookups on Telkom LTE lately?
For the last three weeks or so, I've had patches where I need to continually reboot my B618-65d in order for pages to load. I'm talking maybe 8 or 9 hour stretches where I need to reboot every 15 or so minutes.
Huawei B618-65d, running Telkom Uncapped LTE, 1800MHz frequency band, and signal stats seem good too:
| PCI: | 121 |
| CELL_ID: | 13155340 |
| RSRQ: | -6dB |
| RSRP: | -80dBm |
| SINR: | 11dB |
| PLMN: | 65502 |
Running a Smokeping tells me that the pings are still up, aside from the odd packet that gets lost in transit, but it seems like DNS queries stop. I have confirmed this by sniffing the packets going out my WAN interface of my Edgerouter.
If I sniff port 53, then I can see requests coming from the WAN interface to my specified nameservers (I tested with 1.1.1.1, 1.0.0.1, 8.8.8.8, 9.9.9.9, 208.67.222.222, 208.67.220.220) but I then do not receive a reply back. If I reboot the router, and immediately afterwards to a packet sniff on port 53, I see that I am getting replies back over the interface.
I've partially mitigated this by installing cloudflared on my Pi, and pointing all my DNS requests to the Pi-Hole which then forwards the requests to cloudflared which sends the DNS request over HTTPS. Doing another packet sniff, I can confirm that no port 53 traffic is running over the WAN interface besides my TV box that has hardcoded DNS servers.
Existing streams seem to keep running, probably because the connection is already made and there is no need to re-request the IP address. This means that Youtube and Netflix still works, provided you don't browse for other channels or shows. My OneDrive uploads are also still running.
I have logged a complaint on Icasa's site, but I don't expect a reply for a few days.
Just wanting to know if anyone else here has had a similar issue lately, and if you have found any resolution.
Ta!
