Laptop Wi-Fi signal very poor?

I get Wi-Fi in most places around the house on my iphone and iPad but on my laptop the Wi-Fi stopped working so I had to connect it to hub with lead to get any internet, when I got it working again I could only get Wi-Fi on my laptop if I was in the room with the hub or directly in the room above, any ideas on why my laptop won't pick up signal anywhere?

Try to update drivers of it or replace it

What did you do to get it working again? Was the Wi-Fi card removed/replaced? If so maybe the wires were not re-attached properly, these act as the ariel and is not attached properly will be very weak in picking up the signal.

  • Why is T-Mobile's signal so poor? My friend did a carrier settings update on her iPhone 5c and her signal went from LTE to even more Edge 2G than usual.
  • Why do I do this? I'm very very very tired yet I don't want to sleep? I want to sleep because I'm practically blinking and bobbing my head side to side like a drunken man but I just don't want to sleep. I watch tv or go on Facebook or play on my iPhone. And I'm starting to get dark circles. And as a guy I don't wear. Concealer or whatever
  • Poor Wi-Fi signal tablet netbook? My 7" Android Tablet Netbook gets signal but then it says not in range no matter how close I'm to the router. I'm getting Wi-Fi on all my other devices including an iPhone 3GS. I actually haven't let it charge for a full 4 hours, but it says its charged. Should I let it charge the ful 4 hours and let it charge, then try setting my Wi-Fi back up to it, or could it be a technical problem? Need feedback!
  • My iphone screen is very dark, but if I look very close, I see the apps slightly? My iphone screen is very dark but I still see the buttons slightly, but I have to look very closely in order to. It is definitely not the brightness, because the brightness is set to 100% and its way too dark anyway. I tried restoring my phone and turning it on and off, but nothing is working. Please help. What do I do? I literally threw it out of anger and its fixed.
