WiFi not working on your sister's laptop.
WiFi not working on your sister's laptop.
I'm really glad to have finally switched to gig speed via optimum. At first, I used a Google WiFi mesh system but had to replace it because the new modem router combined with my sister's Ethernet connection. She definitely has a built-in Wi-Fi card on her computer—she had one before I connected her, but I can't locate it now. I also can't get online through Wi-Fi, and I'm unsure what steps to take. The drivers for her Wi-Fi card seem to be missing. I don’t have detailed instructions, but anyone, do you think this is worth trying? If I connect everything via Ethernet instead of a bridge, that would be better. Also, would it make sense to speed up multiple devices at once—like two smart TVs and a printer—rather than just one thing? Thanks a lot!
Verify that the Wi-Fi card remains enabled. Then, inspect the device to confirm the Wi-Fi module is properly linked.
On all network adapters I notice only "WAN miniport (XXXXXXX)". It seems the Wi-Fi card is integrated into the motherboard. I’ll check—I found an old 100ft Ethernet cable, so I’ll attempt to download a virus while you wait for my next helpful reply, lmao!
I solved the issue. She had a faulty USB Wi-Fi card installed before I connected her, and she only informed me now. The tiny USB device seems to be broken or we experienced a dead zone—my phone still gets 300 Mbps, so I’m not sure. Do you have any solid Wi-Fi card suggestions?
This item should function well; I only have information about its availability. https://www.amazon.com/Wireless-desktop-...989&sr=8-4
Why not check her laptop first to confirm a WiFi card slot is available? If an M.2 slot exists, simply install one—it performs significantly better than USB options. Ethernet connections consistently deliver faster and more stable performance. With fewer wireless devices in use, interference drops and speed improves. I’ve noticed this especially with smart devices like TVs and media sticks (e.g., Fire Stick, Roku) that typically operate on the 2.4GHz band. I used USB-to-ethernet adapters for those, though they maxed out at around 100Mbps. This reduced the number of competing wireless signals in my 2.4GHz space, leading to quicker load times, less buffering, and better video quality. Devices such as smart bulbs or hubs that need WiFi are exceptions. If you can set up Ethernet properly without disrupting others, go for it!
I began experimenting since my TV has an Ethernet port. I installed this questionable app to test Wi-Fi speeds, and discovered it performs much better via my TV—about 200Mbps wirelessly versus 90Mbps over a Cat6 cable. That’s pretty impressive, even if it’s not ideal. Thanks for the assistance!
