Computer wifi problem.

[Parliament 14377]

I can hook up a hard wire and get +600 mps.  Flip to wifi and nothing.  Steps taken:

Confirmed wifi connection works on for my phone and another laptop.  Works good and fast.
Logged out of wifi connection and back in.
Reset the wifi network on the laptop.

Still no go.  Running on a hard wire run across the kitchen and living room.  What's my next step here?

Pro tip: When you build or remodel a house, put Cat 5 ports everywhere.  The wireless future turned out to be a dystopia.

What OS?  Assuming you’ve legit rebooted the system and router (you never know), and the issue happens even sitting right next to it: has it worked fine before?

Does it show you connected to the right network in the taskbar icon?

If so can you load the routers config page?  Often address is 192.168.1.254 

If it shows you connected and you can open the routers config page, you likely have an issue where security/MAC filtering settings are blocking your laptop from reaching the outside world over WiFi

The fact that it works over wired is a good sign.  There’s a lot of other possibilities but have to verify where the hangup is first.

Windows 10, on a 4 year old Dell.

I pay for 1 Gig, and usually get 120 mps on wifi.  With a booster it's a little bit faster.  

Flipped to wifi just now, and it's working...at 25 mps.  Not what I usually get.  Gonna run on wifi and see what happens.

This is a screenshot of my settings/configs.  I have no idea what all this means, and I presume you aren't gonna use this to sign me up for porn or anything:

Can you run a speed test on another WiFi device from the same spot?  Curious if it’s only that one device that’s really slow…assuming you were getting the 25mbps while really close to the router?

I was operating under the assumption that you weren’t getting any internet at all on WiFi.  Slow speeds can be a lot of things, it’s possible that a neighbor or other device close by is causing interference.  If other WiFi devices are slow now too you may need to login into your router and change that channel.

I got into the config settings. 

I'll do a reset tonight.

When I originally posted, the PC had no wifi and 600 mps wire.  Laptop and phone had 120 mps wifi, from the same place.

Now they all have wifi, but slow:  20 mps on my PC, phone and laptop.  That's abnormally slow.

That second image is your WAN status = connection from router to the internet…we know that’s fine because wired works well. 
 

Often there’s an advanced section in the wireless config, that may need a special password from the bottom of the physical router to get.  If you get into the advanced section, try changing the ‘channel’ for it…on mine there’s an ‘auto scan’ setting that’ll look for the channel with the least interference.  If all WiFi is slow but wired is fine, likely something is conflicting with your signal…neighbors WiFi, microwave, your wife’s dildo, something.  Changing channel can resolve interference.

This?

There's an auto.  I'm there now.  Will run for awhile and check back.

I live in an apartment and got some new neighbors.  A coven of lesbians it looks.  Lotsa dildos I bet.

Yep that’s it.  Try changing that channel a few times, or try auto first…but if auto ends up on the same channel then try manual changes.  May take a few tries, testing speed each time. 
 

Not saying that def the answer but that’s what channels are there for, interference. 
 

Also always worth resetting your router

Had a similar issue with the wife's laptop today.

Wifi worked for both our phones but not her laptop. I turned on my phone's Hotspot and the laptop connected.

When I went to my machine and looked at the router details, it turned out that my 5 GHz radio was off, but the 2.4 GHz was on... I tried multiple times to restart/enable it, but no joy.

I restarted the router/gateway (ATT Uverse), and it popped on without issue, and her laptop connected.

Tldr; Restart your router.

Make sure DHCP is turned on. Your ISP only gives you one IP address so you must have DHCP on in order to connect multiple devices.

I finally had to unplug my SmartThings hub since it was causing too much interference with the main router. 

[Parliament 14377]

Update.  That channel change and overnight router reset got me 100 mps.  Not what I'm used to, but it'll work.  It'll work so long as it doesn't sketch out during the day.

Make sure and install the latest driver as well:
