XZ Premium cannot reconnect to WiFi after Oreo

RussianOne1 — Sun, 12 Nov 2017 20:07:00 GMT

Hi there!

After update to Oreo my XZ Premium (and my XZ1 Compact) sometimes (but not always) cannot reconnect to saved WiFi networks. Even if I go to WiFi settings and force it to connect via menu it still cannot connect. It connects smoothly after restart. Very annoying.

Another interesting bug is that sometimes it takes my phone quite a while to open address book. Restart cures this one too.

Any idea?

Hi @RussianOne, I am sorry to hear about this

Do you experience the same issue in safe mode?

I actually never tried because I cannot afford running the phone in safe mode for a day or two. I understand it may be caused by third-party apps, however.

The very fact that it started with Oreo update in XZ Premium and it was the case with XZ1 Compact out of the box tells me there is something wrong with the OS.

Am I the only one having this issue?

@RussianOne

My WiFi works perfectly, I own a Single SIM XZP. Do you have the Single or Dual SIM variant?

I see the WiFi issue too. Dual SIM. Toggling WiFi on and off fixes it. Very annoying.

Only thing that fixes it is a reboot and then its fine but after a few hours same thing over and over. This is a bug, note Oreo on Google Pixel phones caused the same problem, just google it... Can someone in Sony please admit there is a bug and sort please ASAP

Would anyone with problems with their wifi connection constantly dropping please post here. Since Oreo updated having endless cases of wifi disconnecting and need to reboot phone to reconnect. All obvious stuff tried and Sony support no help just suggesting basic fixes none of which work. Oreo wifi problems seem to be bugging Pixel phones too but why on earth did Sony release 8 if it is so buggy?? And not test it properly????

Please post here if you are having problems!!

I've read an article saying it's Android 8.0 issue with WEP.

Even if you are NOT connecting your router with WEP, Wifi disconnectivity issue can happen as long as the rounter is set to be compatiable with WEP.

So the only way to resolve the issue is to disable WEP on the router, or choose WPA/WPA2 only.

Try this, and hope this works.

Thanks Jotaro identical problem.

Ok thanks but work network and so many networks use wep its not practical to get them to change just because Sony/Google cant fix a simple software glitch.

Can someone in Sony explain that they are working on this please????

I find it hard to believe that any reputable company WiFi is still using WEP for security. I work in IT and WEP is the least secure of them all...easily cracked. So if they are using WEP then they need to get with the program already. Why should any software company make their WiFi code compatible with something that was replaced long ago with encryption that is many, many times better? Just check your home router and make sure you are not using WEP. Then see if it helps.

What a ridiculous post, from experience many wifi networks from coffee shops to home networks to some business networks for visitor wifi still use WEP, I know it can be hacked but that is not the point. It is a wifi standard still in use. Jo Punter who just wants to hop onto a wifi network doesnt care about the security protocol used. If Sony update software that means it wont work with many wifi networks just because some techie thinks one form of encryption is obsolete then we should be told in advance. The reality is if I follow your logic is that you think its perfectly ok for Sony to release a top end phone which cant use many wifi networks. Not sensible or acceptable. Will do some further testing over the weekend to see can I confirm that this is a WEP only bug. Would be lovely if someone from Sony actually did their job and didnt leave it to a random customer to try and figure out why their handset wont work on wifi in 2017........nonsense.

Lennyxz,

I completely agree with you.

The security concern about WEP should have nothitng to do the wifi connectivity issue, unless Google or Sony officially announce they don't support WEP

So after all, I think this is still Xperia or OS issue, but my post was simply to introduce walk around, not "fix".

Re: Wifi Issues Oreo / Xperia-XZ-Premium

Lennyxz — Fri, 01 Dec 2017 20:32:26 GMT

Thanks and really appreciate your workaround at least it would give some assistance to people who may have a router at home using wep, will try and narrow it down by doing some more testing.

Just fed up after numerous support emails, phone calls and hours messing resetting phones that no one from Sony will admit there is a problem and just get on and fix it, very poor customer service.

Lennyxz — Fri, 01 Dec 2017 22:29:55 GMT

Ok spent sometime testing and I am having the same problem on wep and wpa encryption, defintely happening on my home wifi regardless as to whether it is wep or wpa.

Sony please can you get on this!!!

Just got the same issue today. Updated to Oreo 1week ago. In my case even a reboot doesn't help. I simply cannot detect any nearby Wifi networks. Sometimes the detection comes back up for few seconds and then breaks again.

Sorry to state the obvious but anyone having this wifi problem post oreo could they please log it officially with sony support so maybe they will actyally recogniae it exists and fix it.
