Q: wifi problems ios 7.0.3

No.

maybe you can tell a little more about, WHAT your problem is.?

I have been having problems since the iOS 7 upgrade on my iPhone 5, and 7.0.3 did not fix them. I have trouble connecting to wifi, and even when I do I have difficulty opening web pages and connecting to online services. I've done the quick fixes like a network settings reset and removing the apostrophe from my phone's name, but they seemed to have a temporary effect.

Hi

Even I am facing issues connecting to my wifi on iPad but for iPhone the same wifi works

I don't know if it's a bug for iOS 7.0.3 or issue with my iPad

Both of them are running on iOS 7.0.3

settings>general>reset>reset network settings

totally having the same problems.  Phone shows its connected to wifi but no connectivity.  Turn wifi off and 3G kicks in and works.

I have reset the Network Settings but still getting the same problem

Total nightmare as its happening on all routers and wifi connections

If you get a fix hit me up

Cheers

I also got problem with my iPhone 5S since 7.0.3.

It will not reconnect when I open my phone.

Have tried remove and add my wifi, but it will not work.

Hopefully it will come a patch soon.

New 5s worked perfectly over WiFi until upgrade to 7.0.3. Now can't recognise or hold WiFi connections. 3G data performance appears to have worsened too. Help!

Yup, iPhone 5s, iOS 7.0.3 has messed up my wifi. It still works, but the signal strength is far worse than it used to be. I have two Airport Extremes, and used to have full strength signal most of the time. Now I can barely connect and frequently drop the network. HIGHLY ANNOYING I might add....

If that doesn't help, tap Settings > General > Reset > Reset Network Settings

I already tried that. Didn't help... 

settings>cellular>toggle off and on

if that doesnt  work

Go to settings>icloud>storage and back up>back up

or back it up to a computer

after that preform a restore by going to

general>reset>erase all content and settings

this will delete everything except the enabled stuff on icloud.

You can view whats enabled by going to icloud in settings.

Me too

iPhone 5s 32GB worked perfect until upgrade to 7.0.3

Won't recognise home WiFi network, can't see other WiFi networks in range, association problems with WiFi networks. 3G data also severerly impacted along with complaints that the quality of voice calls has degraded severely.

I've tried:

Settings > General > Reset > Reset network settings x 3 times - No joy

plus

Settings > General > Reset > Erase All Content and Settings x 4 times and backup or new phone setup via iTunes - Still no joy

I have similar situation.  Updated our iphone 5 to version 7.0.3.  Now, the phone's Wifi no longer works.  It shows it's connected to wifi, but can access nothing.  I have ipad 3 on the same network which has also been updated to 7.0.3 -- and it accesses wifi OK.

I have tried forgetting and re-establishing network, doing a reset network settings on phone, resetting my router -- in various order.  Nothing changes phone's inability to access wifi.  The phone can access 3G.  Not sure what else to do...

I have the same problem. IOS 7.0.3 disrupts wifi on ipad2.  Resetting everything several times has no effect.
