Hi. So, I've had this computer for almost 2 years now.
Recently the battery started swelling and I took it out and ordered a replacement, and have been using the laptop without a battery (plugged in) for the last few days until the new battery arrives.
However, ever since I removed the battery, the wifi connection has been TERRIBLE. It frequently disconnects, sometimes even every few minutes, and I usually have only 1 or 2 bars where I used to have full signal. When it disconnects though, the bars remain in the icon (it doesn't turn into the "offline" or "problem" symbol), but nothing will load, browsers tell me I have no internet, etc. and this persists until I disconnect and then reconnect to the network. Also, I'm not sure if this is related, but the "connect automatically" button won't stay checked. Every time I disconnect, I check the button, and then next time I have to connect it's come unchecked again. The network driver is up to date.
This is super frustrating and makes gaming and calling with friends online basically impossible. Is it somehow possible that when I opened up the laptop to remove the battery, it affected the wifi card or something? This issue only started right after that, and I've never had this problem before in the 2 years I've had this laptop. If anyone can give me any help, it would be greatly appreciated.

I had the same problem. I updated the BIOS and drivers, but until I replaced the Wifi card, nothing worked. Just replace the card. I ordered a Intel 8260 IEEE 802.11ac - Wi-Fi Adapter from Amazon and it works great in my 9350.
