Update 5:
April 14th software update- good so far.
Update 4:
Going longer between freezes. Days to weeks now. Just make sure all updates are done (playstore and galaxy store)
Update 3:
Bluetooth started losing connection as well. The behavior of both wifi and Bluetooth similar to being "almost" out of range (Bluetooth started to crackle) Resetting etc helps for a bit. Done all the troubleshooting, going to exchange my phone.
Update 2:
Problems resurfaced and got progressively worse, especially on the 2.4 Ghz band. I went back to my 10 year old Linksys router and now on the 3rd day with no problems. I was told by Verizon the software patch to fix it supposed to be available on March 23rd.
Update:
had failed again, went into phones safe mode, failed after 8 hours. Looked at router, TP-LINK ax11000, required a software update. Now 24 hours without issue. Will keep you posted!
Original message:
Just got my s23 ultra 4 days ago had mega issues with WIFI 6, on both 5Ghz and 2.4 Ghz, the latter exhibiting same problem after 3rd day. Instead of disabling WIFI 6 on my router, or returning the phone as some had suggested, I contacted a Verizon tech to get some help. After a long discussion, I was convinced that it wasn't hardware, 1% of phones have wifi issues, and of those 95% are taken care of with some sort of reset. Long story short, it usually is some communication/Mac address problem, can affect 1 devide yet not another. I powered my router down, waited 30 seconds, powered up. On the phone end, under intelligent settings, switch to mobile and switch to better wifi off. Under wifi>advanced settings>manage networks, delete all, let the phone rediscover and connected to 5Ghz. Now running smoothly 3 hours, a new record, keeping fingers crossed!
My issues continued even after March update. Wifi 5 on 5Ghz is unusable, the phone disconnects freq. from the network with all the workarounds tried. The only solution for me now was to switch the phone to 2.4Ghz until Samsung decides to fix this mess.
