[SOLVED] DHCP timeout for wifi device
Today my laptop started having issues with connecting to my wireless router. It seems like DHCP is timing out. Other laptops and phones have no issues connecting to the router. But my laptop doesnt want to connect. Any help resolving this issue would be greatly appreciated.

Re: [SOLVED] DHCP timeout for wifi device
And if you remove NetworkManager and just connect manually?

Re: [SOLVED] DHCP timeout for wifi device
NM's own DHCP client can be quite buggy, you might want to try and switch that to a more mature client: https://wiki.archlinux.org/index.php/Ne … HCP_client

I havent tried it manually. Any links to how I should set it up manually would be helpful. I can try it out.

Changing to dhclient didnt make any difference. It still timesout. I event did the configuration of mac address in dhclient.conf.
On a side note could it be an issue with a specific gateway, I have the Att Pace 5268AC.

Re: [SOLVED] DHCP timeout for wifi device
Seems like reseting the att gateway solved my issue. Regardless, I would like to know how to try the connection manually without network manager.
