I picked up my new Galaxy S5 on Thursday and I'm having issues getting it to reliably connect to my 5GHz wifi network at home. It will initially connect but the connection will only last for upto an hour before it drops it. The time before the drop appears to be random. After it get dropped the phone will not connect to the network for 5-10 minutes. The phone works flawlessly when I use the same router in 2.4GHz mode. (Router = ASUS RT-66u)
I've tried Rogers tech support and got passed around 4 times before reaching someone saying that Rogers doesn't support 5Ghz wifi. Even though the device they sold me does. They were no help. I have changed the IP Settings from DCHP to static. No dice.
Is anyone else having issues with their S5 on a 5GHz network?
I don’t have an S5 but I’ve experienced similar issues with some other devices; play around with the 5ghz channels on your router; there might be overlaps from other networks or the handset has a "preferable" setup
Dialpad, *#0011# . When you hit the last # a service mode screen automatically appears.
Hit the menu button, then pick Wifi.
On the next screen you'll see a bunch of settings printed, and one big button under "WIFI Power Save Mode". Tap that button to make it say "OFF". Back button your way out. Reboot the phone, then go back into *#0011# -> Wifi to verify that Wifi power save is still off (a bug in earlier Samsung versions defaults this to "on").
This does not work as a solution for me. There seems to be a major problem with advanced wi-fi. There is no option to select DHCP or Static only proxy and hangs when in advanced settings. It never connects to 5Ghz on 2.4Ghz. I just traded up my Samsung S3 to S5. It worked seamless on 5Ghz. It is the same home network and no changes. My iPad connects to 5Ghz with no issues. I'm stumped I bet there has to be a software/firmware fix for wi-fi or just a bad wi-fi adapter. Any other ideas? Thanks
