After iphone 4 4.3.3 update wifi not working

I'd like to chime in here. I too have lost wifi connectivity. I do have the WIFI option, but even when standing next to my router, I lose connectivity. Come on Apple....

I have the same problem - wifi signal comes and goes as it pleases! Tried this at home and at work - cant be a router issue atall. Not just that - none of the wifi dependent apps work on my iphone4 - no youtube, no linkedin, facebook works partially. But i got 4.3.3 quite sometime back - this problems been around since yesterday only.

I mustve got ahead of myself on this - my ip4 is back to working normally - did a restore and it worked. Happy now!

Same problem for me...

'Upgraded' to 4.3.3, now my WiFi is incredibly weak, and my GPS has stopped. Massive pain in the backside, as I need to use the GPS for work at the moment.

I'm confident Apple will fix this, but it'd be nice to get more info than is on the hacker forums. My iphone isn't jailbroken (just unlocked from O2 by them).

Should add that I've just found out my Bluetooth doesn't work either. Really desperate to get this sorted now...

Hurrah! I don't know how ..... but suddenly my Ipad 64 gb WIFI started work well. I haven't done anything so I think that Apple has resolved the bug.

Hi everyone

also had problems connecting wifi with iphone ios 4.3.3 i tried all the suggested things = forget network, hard restart etc finally did what someone suggested ( i think on this forum) did a reset of router - sorry not technical at all - on our router there is a small hole - pressed it with a pin - router reset (ok had to redo all settings on home pc - with help from our service provider) and what joy - iphone connected and is still connected hours later, So try this.

Regards from South Africa (and to our friend from Italy)

I think I fixed it for my phone. I replaced the Wifi antenna. I think that the problem appeared after the 4.3.3 upgrade by chance, but it was actually a hardware issue.

I have these same problems with wifi connecting after 4.3.3. Called apple and they replaced my phone said that it was a hardware issue with the wifi anntena, Paid $70 for the apple care and they shipped no charge. Got the new phone and updated with back up. I continue to have the same problem, low or no connection at home with great connection at work. Please Apple fix this issue its obviously not a hardware issue.

Ditto with everyone else. I updated my iphone 4 to 4.3.3. Right afterwards the iphone would search for a wifi signal and never find any. So I did a hard reset, then reset the network settings. Now the wifi is greyed out. I agree with a previous poster in that it (logically) can NOT be a hardware issue.

Someone at Apple is just afraid to admit their mistake or doesnt want to accept blame for this.

I am upset that my podcasts were downloading from the 3G network and so will cost me more money on my data plan.

I also have three Ipad 2's at home and I upgraded at least 2 of them, but they are only wifi versions and I havent had any issues on them yet. So this may just be an issue with devices with both wifi and 3G.

Hope this at least helps Apple to discover the issue. Every time I call all I get is the support staff trying to get me to buy a care plan. Logic would dictate that if there needs to be an update to the software, then free support should be given for maybe 30 days after the release.

I just updated my software to 4.3.3 but I did so after reading these logs. My wifi on my iPhone is connected and working fine. I updated using my laptop (connected via wifi) my iPhone wifi was connected too when I initiated the update. Success! 🙂

Dear all,

Do you upgrade to fw 4.3.4 for iPhone 4? Did it solve the wifi issue? I still read comment (another topic) from someone who upgrade for iDevice still facing with wifi issue...
