Internet cuts out, but with no indication of lost connection
For about 2 weeks now I've had an ongoing battle with my Internet. It is most noticeable when I first turn the PC on, I will be unable to connect to any webpages for 5-10 minutes. Eventually it starts to work but will frequently stop working for 3-5 minutes at a time. During all of this, there is no indication of there being a problem on my modem/router (I have an Arris SBG6700-AC). Wifi seems to work more often than Ethernet, but it also has frequent connection issues. I checked my Event Log on my router's page and I'm getting all kinds of errors. The most common seem to be
Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out
SYNC Timing Synchronization failure - Failed to receive MAC SYNC frame within time-out period
Started Unicast Maintenance Ranging - No Response received - T3 time-out
These last 2 only happened once from what I can see, but they are 2 of the 3 most recent errors
DHCP WARNING - Non-critical field invalid in response
TLV-11 - unrecognized OID
Most of the time however it doesn't spit out any error (I've been having issues all day today and there isn't an error log today). As of right now I haven't been able to get my Ethernet to work AT ALL, so I'm currently on Wifi. I've seen people with similar issues paste this info so I am going to as well:

The strangest part is most of the time I still have connection to games and spotify without issue when I am unable to connect to webpages. So far I've tried resetting the modem/router, changing the Coxial cable the runs from my wall to my modem/router, Changing the Ethernet cable to various different ports, changing my DNS server to a public one (Google's 8.8.8.8), and nothing has worked
