We have a wifi router set up at home connected to our DSL router. And a lot of computers using it…there’s a desktop (connected to the router via a wired connection), 6 laptops, an ipad and a few internet-capable cellphones (yeah, there are a lot of us at home)

Sometimes our internet will “act up”, meaning some of the wireless devices will register as being connected to the access point but unable to access any sites. In such a case the other devices seem to be access the internet just fine.

I’m wondering if there’s some sort of limit or anything to the number of wireless devices we should be allowing to access the router that causes this problem? What things do I need to check?


This is very similar to the question:

Things not mentioned there:

  • It’s wireless, so there are obviously going to be interference and signal strength issues to consider.
  • Setting up your wireless security is essential to make sure you don’t have more wireless devices on your network than you expect. =)
  • Even though you’re probably not using too many addresses or ports at once, it’s possible that your router isn’t “signing them in” properly when you restart or disconnect/reconnect devices, and so after a while it starts to run out. Look for more info about problems with your specific router model.
You need a way to figure out if it’s a problem with wireless interference and your wireless devices’ signal strength. When one of the devices “acts up” can move it closer to the router to see if the problem goes away?

Also any other details you can provide about your network would be helpful, e.g.:

  • What kind of router
  • How your IP addresses are set up
  • What troubleshooting you’ve tried on the devices having the problems
I had this problem. I found if I unplugged the wired network from the router then all the wireless devices connected fine. If I plugged in the wired network then some wireless devices worked and other didn’t. I diagnosed it by unplugging everything on the lan and re-connecting them one at a time, until I found that I had put the network in the wrong socket on my FON wireless access point. I plugged it in where it said “internet” not where it said “computer”, and all was well.
