Today's been a busier than usual day. I'm rather tired, but also feel like I've been productive and can rest well knowing I actually did positive things. I was going to sit down and play something for 20 minutes before bed (at 11:40pm - 50 minutes ago), but then I started getting internet issues again :(
Could've ignored it as it's only happening with ethernet, not wifi. But nooooooo I just had to try and fix it. Spoiler alert: I don't know what's broken, so I can't fix it. 40 minutes later, all I know is that the router isn't assigning an IP configuration to the PC via ethernet, for some reason. I've run windows near useless network troubleshooter, all it's telling me is that "'ethernet' doesn't have a valid IP configuration". I said to the troubleshooter "well can ya fix it?" Troubleshooter said "nah fuck off mate I'm on midnight smoko m8" and marked it with a giant X that says "NOT FIXED."
The error page the router was displaying before (over wifi) was saying something about contacting the ISP to fix a DHCP issue. Nothing more. Although it stopped after a restart. But that seems like a bad omen. I haven't touched the DHCP settings, in fact I can't even find the DHCP settings in the router settings. So it seems like it broke on its own.
I like playing junior network engineer though, so I guess it's just one more problem to try and solve. But I would rather have been able to get my 20 mins of gaming in
Ok,
What you're describing kinda sounds like different issues.
Dhcp from isp is your public ip, that doesn't sound like it's faulting if the wifi is working.
If windows is being a dick, have you tried resetting the network stack? You'll need to reboot afterwards, but open up a commandline and netsh int ip reset rlog.txt
Seems to be the former from what I can tell. Unsure about the latter. My phone was yelling a generic "Saved / won't connect with current security settings", and wouldn't connect when I tried to turn off mobile data and force it to connect. After trying to force it enough, it prompted me for a password, and nothing changed when I re-entered the password.
I checked the NBN modem and it had solid green lights for up/downstream, power, and internet, so I'm guessing it's a router problem. LAN still isn't working, with any device, although the wifi is now fixed after a reboot 🤷‍♂️
