Hi, I've been having a strange issue that Sonic has not been able to resolve, so maybe someone here has insight or a suggestion.

Background
- Been a Sonic Fusion customer for over 10 years
- Roughly 10 weeks ago, my line was cut. AT&T came out and repaired it by using a previously unlit line.
- Since that repair, about 1-2 times a day, I would lose all ability to resolve DNS
- BGW210-700 modem (so cannot set DNS directly on this model of modem)
- Cannot resolve any hostname.
- Can see other devices on my network.
- During an outage, I cannot establish a new VPN connection, either to my office, any 3rd party VPN, or even Sonic VPN.
- During an outage,any previously-established VPN connections, work just fine. Able to resolve hostnames on the VPN connection.
- I setup a PC such that one browser is shunted through VPN while another browser is not. The browser that is shunted through VPN can browse the web while the browser that isn't cannot.
- Similar behavior on all devices, including PCs using ethernet, PCs using wifi, and mobile devices. Tested on Windows 11, Mac OS Ventura, iOS 16, and Linux kernel 4.19.97.
- Connection line is from AT&T and they are known to poison/hijack DNS.
- Replaced the modem. Did not improve things.
- Technician "changed some modem settings". Did not tell me what settings were changed. Did not improve things. Did however verify that my modem is using the correct firmware.
