I have a Lenovo Ideapad N580. And it was working fine until a few weeks ago. My Wi-Fi signal is only 3-1 bars, but I'm only 15 feet away from the router. My mother's and sister laptops are connecting fine and there and my smart phone is fine, and my sister is further away, so it's my laptop.
I did two factory resets but to no avail. I took the back off and unplugged the two Wi-Fi cords, u plugged there called antanas I may be wrong. But I unplugged and plugged them back in, still low connection. They aren't tangled or lose there fine.
I can connect to the Wi-Fi but it's just a low signal? When I plug Ethernet is faster. But no one want to do that. I can be right next to the router but only have 4 bars max… I don't gave my warranty anymore so can't send it to Lenovo. Is there away I can solve this at home? I'm a little tech-savvy.
