2g Wi fi stops working, stays showing as connected. - Xperia Z5 Q&A, Help & Troubleshooting

Has anyone had the issue where wifi although showing as connected stops working for 30 seconds or so whilst throwing up dns errors in chrome, then start working again?
It's just cost me a corrupted save in Fallout Shelter!
5g works OK, just 2g with the problem.

3G connection issues (Focus)

I'm having random 3G connection issues on my Samsung Focus.
At radndom times 3G connection is lost and the only way to get it working is to turn off and on the phone.
I tried putting the phone into airplane mode, turn off/on data, turn 3G off/on, nothing works, only a reboot works.
Today I checked my email on my phone and it says;
Last updated 4 hours ago
We're having a problem connection to exchange.xxx.com. Try again later.

Error code: 80072FA8
This error shows up on all 3 emails I have setup.
IE doesn't work, Zune, any app requiring 3G connection.
And this happens at random times, at least once a day.
The phone has the lastest updates and is jailbroken.
One other thing to mention is, the phone is now having the 3G connection issue but i have it theathering to my computer and the internet connection is working while theathered, cause i'm posting this email.
I have no idea what's happening or how to fix it.
Thanks

WIFI issues. Slooooow out of the blue

Hi there guys. All of a sudden my wifi connection became unusable. I have a 200MB/s dl speed wifi at home, everything was working fine and all of a sudden I couldn't even get my mail, the phone couldn't sign on to the google servers, nothing worked. I have tried data and it works perfectly fine, but wifi nope, it looks like the connection exists but is slower then slow, not alowing even regular functioning.
forget the network then try and reconnect, maybe that helps. also reboot router and phone...

CM 13 snapshot, wifi and 3g stopped working

Hi.
Im using cm-13.0-20161115-SNAPSHOT-ZNH5YAO2Y1-peregrine on my MOTO XT1040.
Everything works fine, but after some time (couple of hours) the wifi and the 3g network stop connecting. For wifi I get the "obtaining ip adress" loop without ever connecting.
And for the 3g I get the bars with the sclamation points.
Restarting the device fixes the issue.
Any idea how to fix this without having to restart everytime?.
Thanks.

Open WiFi appears to be causing my mobile network to become unresponsive?

As of yesterday I'm having a very strange issue. At the local coffee shop that I'm at to do work which normally has not given me any issue, suddenly my LTE on my pixel 2 stopped working. SMS and the internet were unresponsive.
The network would cycle between no service, 3G, H, and periodically work for a moment, then die again. Last night and today I noticed when I left and was away from this location, LTE resumes normally.
Another strange symptom is if I enable WiFi, everything goes back to normal. Anyone experienced this before?

WiFi & LTE Connection Issues

Hello all!
My wife is running a T-Mobile Note 10+ and having major issues with the WiFi and mobile cell service. She constantly runs into her apps like Netflix and Plex saying she has no connection. She's complained of the WiFi being bad and having to disconnect from it, and then she can use LTE to watch shows, and then sometimes LTE stops working and connecting to WiFi fixes it.
Here's the thing. I finally was able to see it when it was having a fit on the WiFi. Going into the connection settings showed it was connected to our 5GHz WiFi at 7Mbps connection speed. Nothing was loading. This was on a 1300Mbps link. I disconnected from the WiFi and reconnected to it, without moving the phone's location, and voila! It reconnected at 300 something Mbps and everything started working. I believe it may be doing the same with LTE as it cuts out randomly and constantly. I saw it myself while we were driving somewhere and she couldn't load websites. My phone (OnePlus 7 Pro) is on T-Mobile as well and I have NEVER run into these issues. We are on the same provider / plan.
Her phone is fully updated and isn't rooted. I haven't touched it as a tech nerd so it's running as a total consumer as far as settings go (haven't played with APN or wireless radio or anything).
Has anyone else experienced these issues? Does anyone have any ideas to fix this?
Did you try a different wlan access point? Actually i am on the Note 10 with Exynos. Wlan and LTE are working nice for me.
Perhaps your problem is meanwhile solved through an update.
I have the same problem, mainly in LTe but sometimes also in Wifi
ANyone found a workaround ?
i've been having this issue constantly since the march security update. Didn't notice it before but it'll disconnect from my wifi, still recognise it but wont reconnect unless i restart my phone
Same here. Brazil SM-N975F.
