Can't connect to router after update

Last night I updated my 360 (it failed once during the update but finished).  I played some Dragon Age and then went to sleep.  This morning, like a lot of other people, I can't connect to Live.

What Country/State/Province do you live in? South Africa, Gauteng
Modem brand & model number: Huawei, SmartAX Mt880a
Router brand & model number: TRENDnet TEW-652BRP
Network Connection Type: Wireless
If Wireless, what type of encryption are you using? WPA2-PSK
Things you have tried: I've got three computers in the house that's connected.  Switched them all off and switched the 360 off plus the modem and router. Switched modem and router back on with the 360. I tried to set the IP manually but was unsuccessful.  The 360 sees the connection and everything else connects like normal.  It's only since the update that the 360 fails.
Is UPnP Enabled? Unknown
Is NAT Type Open? Not entirely sure what that means. NAT is set to Enabled and Obtain an IP automatically.
Any Error Codes you encounter: None
What type of internet do you have? ADSL
Who is your ISP(Internet Service Provider)?
TelkomSA, also tried others
When you run "Test Xbox LIVE connection" what is the exact message shown on screen?

Can't obtain an IP address from your router or modem.

Turn your router or modem off and back on, then wait 30 seconds.

Have you restarted your router or modem?

 

And that's about it.  It's frustratring.  Oh, it's one of the new Slim models.  I bought it new in December with a Kinect.

And now for an interesting point.  After some testing I realized that if I set my router to Wireless G instead of Wireless N then the XBox can connect.  The update screwed up the 360's N connection somehow.  The console is only about 3 meters away from my router.

But yes, I've got a slower network now but at least the XBox can connect.  So everyone who has the same problem, please try it out but still post here because it's something that Microsoft should know about and fix.

Hmmm I'm using WPA2-PSK.  Will have a look at AES.  Thanks Shado0wmanUK, will test it out tomorrow morning.

Ok

 

Sorry I should have explained you can use:-

 

  • WPA2-PSK (TKIP)
  • WPA2-PSK (AES)
  • WPA2-PSK (Auto) which is AES+TKIP

 

Try using WPA2-PSK (AES)

I am having the exact same problem as you. I have a new 250 Gig wireless and everything has been working fine for weeks untill today's (may 28th) update.

now I am experiencing exact same symptoms as you. My router and firmware are fine, with all my pcs and mac computers still working.

My xbox sees my router and lets me put my password in, and tells me my router is not issuing an IP.  Router UPnP Enabled, and router enabled to issue IP's. I have turned off router and xbox, reset xbox network settings to original to factory settings. no dice. I jumped through the hoops and hasnt worked.  

I hope we can wake up tomorrow and this will be patched

I fixed mine by following Shadowman's instructions; I changed router cipher to WPA2-AES and it worked instantly. thanks.

I haven't had the time yet to check unfortunately.  Worked until late last night and typing this now before going to work again.  I will mark this question as answered though.  Since it worked for SuparFubar and I've got a good feeling that it will for me too.  Plus if it doesn't work then at least I know everything is working using wireless G.

Thanks for the help Shad0wmanUK and thanks for the update SuparFubar.

How do you switch to Wireless G? That's really annoying and a big problem for me. My router is ages away from my xbox and I already have a very slow internet connection. I hope it isn't much worse if I have to change it.

Jay, it depends on your router make/model, its easy enough to do once you have access to the routers menu via your browser, if your not sure download a manual for your router.
