"Internet connection is unstable" issue
OK, I've seen a lot of posts in various forums about this issue, but have yet to find a single thread that captures all the details about what I've experienced. Let me know if I should move this conversation into a different thread.
On my home wifi network, I am able to connect, but constantly receive the error "internet connection is unstable", and I cannot pull any data over wifi. I noticed this issue on my home network after returning from a business trip this week. I'd previously seen the issue occasionally in hotels, etc, and had already disabled the "Passpoint" and "Auto network switch settings". That seemed to work on the road, but now that I'm at home, I'm unable to pull any data over wifi.
My home router is a TP-Link Archer C7, running the latest firmware.
Per Verizon and Samsung's advice, I cleared the cache partition, "forgot" and reconnected to the network, tried using safe mode, and tried a factory reset of the phone. I also restarted the router and changed the router's broadcast channels.
Last night, I rooted the phone via Kingo and installed the Jelly 'Beans' rom using SafeStrap, since I wasn't getting satisfactory answers from support. To my surprise, the issue also occurred on the new rom. I'm not an Android expert, but it seems like this means its either:
1) a hardware issue, or
2) a lower-level software issue (radio firmware? not sure how that works)
I removed root and safestrap, to continue support options with Verizon, but I wanted to ping the community here for suggestions. The timing is confusing to me. I'm pretty sure, though not certain, that I've used my home network successfully since the 12/17 OTA update. However, since so many others are seeing issues, it seems unlikely that this is a hardware issue.
Could others describe their issues and router, so we can look for patterns? Let me know if I should move this into a different thread.
