My wifi has been a constant one bar but used to be full

It sounds like you have a Gateway which is a combination Modem and Router.

Did you try contacting your ISP? I solve problems on my home network sometimes quickly by calling them.

If not then I gave you all the other steps that work for others.

When troubleshooting whats most important is thoroughness. We often find out weeks later that the skipped step was the solution.

Hi Kevin. I'm Greg, an installation specialist and 8 year Windows MVP, here to help you.

Have you also noticed the internet slowing? Have you run a speed test?

If you're getting a lot less speed than you pay for, I'd contact your ISP because they're required to provide the speed you pay for or help you to get it.

One test they'll try is to unplug the router and plug directly into the modem to compare speed. This rules out the ISP or modem. At that point you may want to troubleshoot the router, which may also still have support if within a year of purchase. If not there are some good guides online for each brand of router to reset or reconfigure it.

To go over everything else that might apply, see these other steps:

Right click the network icon in System Tray at bottom right end of task bar to Troubleshoot Problems.

Check that the wireless button on a laptop is toggled on. It may be a Function (Fn) key or it may be an actual switch on the side.

Try powering off modem, router and PC and then restarting in that order with 1 minute in between each.

Try updating the Network adapter driver from the PC's Support Downloads webpage. http://answers.microsoft.com/en-us/windows/wiki...

If that doesn't help try Rolling back and then Uninstalling the Network adapter driver in Device Manager. Right click Start to open Device Manager, choose the Network adapter you're using, on Driver tab choose Roll back, restart PC. If that doesn't help ry Uninstall, restart to reinstall.

Try all of these steps: https://support.microsoft.com/en-us/help/10741/...

Go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files. Then continue with the other steps to go over your install most thoroughly.

I'd also check at Settings>Update & Security>Windows Update under Installed Updates if there were WIndows Updates installed before this problem started. You can uninstall them from the link there to see if the problem goes away. If so you can hide the Updates using the same tool above.

You can also try to System Restore to a point before the problem began: http://home.bt.com/tech-gadgets/computing/how-t...

If nothing else helps then run a Repair Install by installing the Media Creation Tool and choosing from it to Upgrade Now. This solves many problems and will also bring it up to the latest version which you need anyway and by the most stable method. http://windows.microsoft.com/en-us/windows-10/m...

You also are entitled to Support from your internet provider to get online on all devices. This is always included in the monthly bill. If your router is less than a year old they will also Support getting it connected.

Another option is you could replace the wireless adapter with an inexpensive USB nano adapter like this one: https://www.amazon.com/dp/B06XSFPDFX/ref=asc_df...

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

So have you begun on the steps I gave you which work for most others with this problem?

What did your ISP provider say as they are required to help you get the speed you pay for as part of your monthly bill?

Please report back results on all steps so we know what you've done and what else to suggest if needed.

i have tried some of the suggestions but they have not worked, i do not have a modem either.

i ran a speed test on both my phone and pc. one is faster than the other, and now i my internet keeps on saying that there is no internet and appearing with the yellow tag on the icon. My wifi is still full bars for my moms laptop and my dads but mine is still one.
