MI3 does not have internet even though its connected to Cisco Router WRT610N router but it does when my iphone shares its hotspot.

It happened just today for some reason. Im on that same network with my mac and iPhone. These are the wifi router settings:

SSID: COMP
B/G Only
Audio Channel - Standard

I saw this somewhere and I fixed it by selecting only one mode on the router, can't remember detail sorry will check my router later

Hi,

Did you check your router by any chance? Mine has a 5GHZ and a 2.4GHz. Ive tried:

2.4GHz Mixed Mode - Doesn't work
2.4GHz G OnlyMode - Doesn't work
2.4GHz N OnlyMode - Doesn't work
2.4GHz B OnlyMode - Doesn't work

5.0GHz Mixed Mode - Doesn't work
5.0GHz A OnlyMode - Doesn't work
5.0GHz N OnlyMode - Doesn't work

OK so I checked, I have ddwrt on my home router, I had set to g only, I know as I wrote it down.
Now it's on "mixed" and the Android phones still work OK, someone in the house has played around with the settings!
Upshot is, mixed is working fine here, not as many options as you on my ddwrt build either.
Sorry I couldn't be more help.
I expected to say g only was the fix, my bad.
