I have a dual-band Netgear router, an iPhone 6 and a MBP 13" early 2015 (Both devices were on Beta tester OS but not anymore).
When I try to connect to the 5GHz network from the router I end up connected but having a self-assigned IP like so (Happens to both my devices):
When I connect to the 5GHz using my phone I also get a self-assigned IP
After connected my devices will assign it self an IPv4 that looks like 169.254.xx.xxx) and obviously I cannot connect to the Internet using this IP.
When I connect to the 2.4GHz, the network becomes insanely slow (Even though the signal strength is at the best), I pinged my router (192.168.1.1) and I end up with average latency of 322ms and a 5.4% Package loss (BTW I'm right in front of the router). Speedtest.net and speediest-cli gives up/download speed test at around 3/1 mbs.
All of my flatmates says the WiFi works fine for them (and they are further away from the router than me)
Here are the solutions I found and tried:
- Turning WiFi connection on and off
- Rebooting my Mac and router
- Forgetting the WiFi and connect again
- Manually setting IPv4
- Setting my DNS to 192.168.1.1
- Disconnect, deleted all the .plist files listed in tutorials and attempt to connect again
- All of above tried again using terminal with sudo
- All of above tried again using terminal with sudo but with
csrutil disablein Recovery mode
None of them worked.
Is there another solution that I haven’t tried? Why does it keep happening to me but not my flatmates? Is there a way to stop Apple devices from self assigning IP addresses?
All I want is to be able to connect to the Internet using the 5GHz (because it working for all others) or at least not having such high latency with the 2.4GHz
