My husband and I both have Samsung Galaxy SII devices, recently updated to the new jelly bean iOS.  We can now no longer have both devices connected to a local WIFI source.

At home we have Rogers internet provider and only 1 of the 2 smartphones can now connect.  Both phones see the WIFI SSID but only 1 connects, while the other saves the WIFI available connection. 

We had no problem at all having both devices connected at the same time to the Rogers WIFI router prior to upgrading the iOS version.

This happens at any house with WIFI signal, only 1 of the 2 phones can connect.

If the 1 phone that is connected is out of range or manually turns off the WIFI connection then the second phone connects no problem.

Both phones have been factory reset multiple times.

This is costing us money now as one of us always goes over our monthly data plan.

Is it possible that both phones are set to the same fixed IP address rather than accepting an assigned IP? Since both can't share the same IP, the first to connect wins.

Someone with more knowledge of the phone would have to provide steps to check this possibility.

What happens if you go to another wifi source like a restaurant or a mall?

 

The problem could be your wifi source.  I know some hotspots only limit you to 5 active devices at the same time.

It is the exact same problem at any house with a router wifi source like Rogers offers.  Our house has the newest-latest- greatest-fastest no limits Rogers Cisco router, and the next house that we've tested at has the basic available Rogers internet router.  Same probelm either house, one of hte phones can connect while the other cannot.

It used to work no problem with the old iOS on the Android phones, it's only since we updated.

I don't usually connect to public wifi spots but the once or twice I have I haven't had any problems.

It's not the house router, I've purchased a second router and tried with it as well with the exact same issue.

Hadn't looked since we are running DHCP on the router, however, I will verify tonight, good thought.

Thanks!  Will update later.

So yes, both phones had the same IP address.  I've managed to fix the connection issue by statically assigning an IP on one of the phones at the house with the basic Rogers cable service, but since playing around with IP addresses at home I now have zero WIFI access on both phones.  Guess that's a call into Rogers.
Thank you for fixing this, never occured to me to look at the DHCP assigned IP on both phones... that's what I get for assuming!

Thanks again.

You can likely reset the Rogers modem, and rebuild from there..... 

 

I hope you are able to fully solve this situation in the near future. Searching on some of the Samsung enthuiast boards might be one way to learn more.

"This happens at any house with WIFI signal, only 1 of the 2 phones can connect."

The issue is not at the router if you experience this at other locations.

 

My guess is that both phones are not connecting using DHCP but using the same fixed default IP address instead.

 

"My husband and I both have Samsung Galaxy SII devices, recently updated to the new jelly bean iOS"

Your Galaxy SII does not use iOS, which is the Apple OS. It uses Android. The Android version, as you state, is Jelly Bean. I suspect that the upgrade has either changed your connection settings or somehow messed up the phone's ability to use DHCP.
