Randomly started getting “No internet access” and when troubleshooting get that error message in the subject of this post.
Ive looked in ipconfig and I noticed I don’t get a default gateway and my autoconfig IPv4 Address is 169.254 range (I’ve read this is a Windows 10 reserved address if the device can’t contact DHCP)
Ive changed all my ethernet cables.
Im running Powerline adapters which go straight into a 4 port switch. I’ve tested with and without the switch and it still persists. I didn’t get the issue when running straight to the hub with a 20 metre cable but it’s not practical at the moment, any ideas? 🙂
Could this be a problem with the hub's DHCP server?
I doubt it very much. A little logical progression with diagnosis would help.
So, no problem with 20m cable direct to hub.
Now try 20m cable to switch - Does it still work? If yes then try Hub to powerline adapters - Does it still work? If yes then it is the switch - powerline at fault.
So when in normal setup, I still have the light on the power line adapters and the switch to say there is an ethernet connection, just my PC says I have no internet access.
When testing, once I knew I had a good connection going straight from the hub to my PC with a 20m cable, I swapped and used a cable from the power line adapter to the PC which is how I came up with it being the power line adapters.
Also it was weird as it seemed intermittent which is why I replaced all my cables. For about 20 minutes it worked perfectly fine through the adapters and the switch then dropped off for about 3 hours, worked for a bit then stopped working again. I tried setting my IP and DNS manually from the information on the Hub Admin Panel but still no luck, still get an auto assigned windows IP and no default gateway.
