Hello everyone!

This is a problem we've had at home for over a year now.

We currently have 2 stationary PC's and 2 Laptop PC's. The WiFi connection seems to work on stationary PC #1, however connection problems occur a few times a week. A router restart usually helps but not always. There is no problem connecting to the network from an Android phone.

On the other PC's a WiFi connection is nearly impossible to get. As mentioned in the title, I can find the network, but when I try to connect it simply says that it cant connect to this network. The signal strength has full bars so range is not a problem. Sometimes I'm able to connect and it says ''internet access'' but I still cant open anything in my browser.In some cases it's connected but it's ''limited''.



Here's what I've done to try fixing the problem:

- Restarting the router
- Updated drivers for the network adapter on all PC's
- Placed the router on different places in my home
- Resetting the whole network and created a new one
- Even went and purchased a new and better router
- I used inSSIDer to find which channel has the least interference and changed to that one.

The final solution was to go with wired connection. I prefer it and it always works, however it is not possible for the other people in the household to drag cables across the house.




The router is a Belkin N600DB Wireless Router and all of the computers has had Windows 7, 8 and currently 10 on two of them. Oh and the PC that doesn't seem to have trouble is running Windows Vista.

I hope my information is sufficient for you guys to help me, if not i'll gladly answer any questions.

If you have only one router/access point, then the most likely cause is usually a minor conflict between devices negotiating modulation standard (AKA "mode" or "speed"). That's the "B", "G", "N", or "AC" WiFi speed protocol that your router supports.

Check the router WiFi settings and see if it is set to a combination type mode. Change it, if possible, to be a single mode. "N" usually works well, and helps all of your devices get along.

If you have an older computer or phone or Roku box that can only get up to "G" (which is OK), then set the router to be "G" only. The "N" capable devices will use that speed just fine, and doing that will keep the router from shifting protocols and dropping connections.

A tiny bit more detail, if wanted:
Routers and access points can be set to support one or several "mixed" protocols. Every make and model of router is different in which combinations of modes that they support. Most will allow setting "N" only, or "G" only, but some will only do a combination of "G/N" or "B/G" or whatever the programmer for that make/model had for a fantasy that day.

The WiFi rules, so to speak, say that routers should step down to support the least common denominator. But,
-- if a computer or phone has already negotiated to run at "N" and then a "G" device comes along, the router might step down to G, but the originally connected device might get confused and not follow the change right away, or
-- the router might get confused by the requested change and just drop everybody for a few minutes, or
-- the router might not step down at all, leaving the older device disconnected, or
-- or any number of other mismatches and blunders between the devices trying to negotiate speed.

If one device demands that your network run at "G" but all the other devices want to run at "N" -- and the router is unable to make up it's mind which to support -- chaos ensues.
