I have to agree something has been going on for at least the last couple of days.
I'll lose Internet access but still connect to the modem and gateway just fine. Zero packet loss to gateway but still no Internet access. Has been happening off and on with no pattern but sure is irritating when in the middle of doing something like downloading a file.
Seems to last maybe 10-20 minutes at a time. Feel bad for you if needing a constant connection for your finance software. Dropping to even 100kbps is better than a total loss for things like that.
I get the below generic error page, when I run the diagnostics it says it can't determine the proxy. Seems like a NAT/Gateway issue.
I'm hoping it is unannounced upgrades to the system going on. Never hurts to be a bit positive I suppose.
Has been better today for me. No loss although not online constantly. Is bad problem as nothing shows up in error reporting. Everything appears fine on client end as far as modem is concerned. No red X's here, all looks fine even when no connection to Internet.
Hard to even prove what is happening. I'll take a bunch of screen snips if it happens again here.
If you need constant connection, even at low speed, I see where this is a big problem. An aggravating thing for me even though I really don't rely on my connection for anything serious.
I did reboot my modem which may have fixed it by flushing its cache.
Can also do this, especially Method 1, to flush your computer cache: https://www.drivethelife.com/windows-10/fix-dns-probe-finished-no-internet-windows-10.html
Is possible a lot of end servers did updates recently for security reasons and such, so DNS cache needs to be refreshed. Both on modem and computer side.
That was odd.... Last disconnect my WiFi on my pc disconnected... Modem is one foot from my PC.
I have not been able to get the Lan to work for this modem. Tried three different computers.
I don't know if this will make any difference, but regarding the LAN connection, if you have a device connected to the modem with said LAN connection, with both being off, try powering the modem, waiting for a few minutes, then powering the PC.
You may have already tried this, but I thought I would mention it. Sometimes I have to start up this way if I'm connecting something new via LAN, as if I just connect it while the modem is already on and running the PC will sometimes not be connected when I power it up, but if first connect the device via LAN then power the modem, then the PC a few minutes later (giving the modem time to fully be ready), it works.
With that said...three PCs not connecting via LAN? That's quite odd, indeed.
