My brother visiting from the UK brought his laptop with him and he is trying to connect to my wireless network; however, my router refuses to give his computer an IP (his computer gets a 169 address). Everything seems to be configured correctly as I currently have two other desktops connected (wired) and one laptop and four phones connected wirelessly. Also, his laptop can connect to my phone's WiFi hotspot, get an IP, and browse the internet, so his laptop's wireless connection seems to be working properly.
Do you guys have any ideas on what's going on?
