A few months ago my Windows 10 laptop started dropping connections to wifi. I have an internal 2.4 GHz card and a 5 GHz USB Wifi adapter and both will not work at the same time. I have the latest Windows 10 on my laptop which is a Lenovo B50-45. The laptop is pretty old and I wonder if some of the connections inside is coming loose or so. Tried numerous things including updating drivers, restarting routers. The laptop can't connect to my phone's hotspot either. Wondering any other way to troubleshoot before I just give up and buy a new laptop?

I mean you could always try resetting Windows to rule out any software/driver issues, but that's a pretty old/basic laptop, so it wouldn't be shock if something is beginning to have issues (like the motherboard).

I mean you could get it diagnosed to see if it's a hardware issue, but the money spent doing that would likely be better spent going towards a new laptop IMO.

Open it up and reattach the antenna, if it doesn't help you might need a new nic.

Your laptop is almost or maybe older than my previous laptop. Computers that have been upgraded to Windows 10 are known to always have problems. If it keeps dropping the connection, have you tried just connecting to another network? If that works, and trying to connect back to your regular network ends up successful, then it usually means that this problem might not be going away anytime soon.

Your problems might get worst as time goes on, from my search on your laptop model, it shows that it came with Windows 7.

Unfortunately the B series is no longer sold. It's closest modern Lenovo relatives are the ThinkPad L15 (comes with Intel only) or IdeaPad 5 (15")(AMD)

I have / had a pair of those b50-45 laptops as well, and they have really crappy Realtek 2.4Ghz N150 wifi cards in them, really, the bottom of the barrel. I had issues with the wifi disconnecting and dropping out, even getting a red X over the wifi icon as it was failing so hard that it dropped off the PCI-E bus. I think that it was overheating, after extended usage.

Some of the fixes that used were, closin the laptop and re-opening the lid, hibernating and doing the same, or actually re-starting.

At one point, the wifi had borked itself so bad, I had the flash the laptop's BIOS to refresh the wifi card's firmware. Maybe try that?

I have had a laptop that had intermittent wifi problems then lost the wireless NIC altogether in the device manager.

I opened it up and reseated the NIC. It has since been working with wifi connections near flawlessly when taking into account the different wifi environments around my area.
