Ooh! I know the answer to this one! It's the Cricket Wi-Fi Manager. It's being overly aggressive in monitoring signal strength of the wi-fi connection, and switching to LTE at the drop of a hat. Just disable the Cricket Wi-Fi Manager in your wireless network settings, and that MIGHT solve your problem as it did for me, unless you're having other issues than I am...
I have been dealing with this issue for the last 4 plus months. I have had 7 phones under the warranty and Cricket as well as Lg are telling me there is no other issue on this phone that they know of. They will keep trading phones but i get less than a week before it happens again. I am so pissed that this issue could have been fixed and i would not have to have gone through this. Is there a fix for sure ???
No help from Cricket Wireless on this. LG-M327 phone on Cricket Wireless doesn't stay connected to any wifi. It disables after 10-15 minutes.
Mobile Networks>Mobile data-enabled over cell network. International data roaming-Off. Disable 2G-enabled. Access Point Names-set back to default
Has been doing this since I got it in June 2018. Got 2 replacement phones and still have same issue. Updated to Andoid 7.0 kernel 3.18.31 build nrd90u in October- no change.
Any suggestions welcome.
