How Do I Detect Intruders On My Wifi

Can anybody direct me to a program that I can install on Windows 8.1 to detect intruders. Or give me any advice on how to look for intruders within Windows. My Wifi used to be no problem and was quite fast. Now I constantly have to reset it. Speed has gone right down. I searched on the net and I found this program. Who's on my Wifi. But haven't installed it yet. Thanks in advance and Kind Regards.

Log onto your router and see how many devices are logged on.

it depends on what router but generally there is an option to view log. that Will show the connections that have been made. I would suggest changing your key first if you suspect intruders

If you are getting poor performance, it could be because a neighbour is using the same wifi channel.

It depends on your router.
You could try asking your internet provider help department or mention who provides your internet and what router you have in case someone on here has the same.

I doubt you have been hacked, it's probably malware, a router fault, or a local area issue with your ISP's equipment.

agree with transformers. nobody can join your network, unless it's not password protected. (I think.......)

You can lose a huge amount of speed if you regularly switch off your router (at night, say). I did this for a while, thinking i was saving a bit of electricity, but it confuses your router and the speed drops. Mine dropped by about 75%, i had to get Openreach to reset it.

You may be right sammboy but isn't there little programs that would make mincemeat of a password. Cracked in a flash.

aircrack can hack wifi passwords but it does take a little effort. Any reason you think someone would?

The password is the only thing keeping it secure, if that was the case nobody would use it.

Nothing wrong with Nir Sofer's programs, that particular one isn't showing you anything windows doesn't show, it's just presenting it in a different format.

As others have said, it's more likely that you've either got a failing router (the box itself or it's external power supply) or your local airspace has become more crowded and you can't use as much of the signal as you used to.

Which router do you have? You can see connected wireless devices. If your router supports it turn on Access Control where you can authorise devices allowed to connect by the MAC Address. Also it will let you block any new devices from connecting. You can also disable SSID broadcast which means when people in your vicinity are scanning wireless networks it will not show up.

I agree with the other above though. Sounds unlikely to be the reason for slow connection speed. Which ISP are you? If you are with Virgin you need to ask them to check the power levels.

Run Speedtest (www.speedtest.net) and report back the speeds compared to your service quoted speeds. If possible run it from a machine connected by Ethernet cable to the router not one connected by wifi.

No no reason other than being in control. If there is anybody on that shouldn't be I want to know about it. And do something about it.
If somebody's using your Wifi they may be up to no good. Which could land you in deep trouble as the owner of the Router.

Start with testing your connection speed with a machine connected by wireless. It means its a problem with the connection. Although you may still have an issue with congestion on a particular channel you are using.

No one has said it but try switching the router off leave it for a few mins and switch it back on. If it doesn't improve Virgin, not sure if you are on Virgin but was mentioned somewhere, will probably ask you to do a hard reset by pushing a pin in the reset button.

Also just in case as most Virgin routers have the same access password, it's normally changeme if you haven't already change this follow instructions on router label as anyone with Virgin will be able to log in and change your password even by sitting outside your house.

Your wifi speed on a laptop is also determined by what your laptop wifi card can cope with, other devices are the same so don't expect full wifi speeds.

All you need to do is find out your IP address. Then copy and paste it into your address bar and you should then be able to login to your router settings and see. To find your IP address simply search in google "What is my IP address" and it will come up.

OP I think you're just being paranoid. Anyway if you're that worried, press the reset button on your router, and then change the two passwords for your router. The one to access the router itself, and the one other devices use to connect to the router.

Yes your right. I'm a bit of a Paranoid. But doesn't it pay to be on the net.

Who is on my wifi is a pretty good program for monitoring your network, you will need to know the MAC addresses and or the identification info of your devices though, this is so you can tell the program that the device is known, and any unknown devices found will be alerted to you by the sound of "unknown device found". whoisonmywifi.com/win…ws/

But there is no better way to protect from others using your wifi than by using MAC filtering on your router.

Yes I just downloaded it and installed It's working pings whenever a connection is made. I tried with my mobile and it showed up in the window. I feel a little safer now. Scanned for virus first none found.Not to say your virus scanner would not find anything. I will look up Mac filtering up. Thanks for your input. Kind Regards

Why not just log in to your router and change the security key. Then reattach your devices. If any one was on your wifi, they won't be anymore. Then see if your speed improves.

The best was to log in to your router is to open a command prompt (windows key and r, type cmd) then type ipconfig. The number next to gateway is your router (probably 192.168.0.1). Type this number into your browser and enter the username and password (probably written on the router).

Change the wifi password and change the router admin password.

Thats correct

Routers have several channels that they use to give you your wifi connection, but once they choose it it stays on that channel.
When your wifi is at it's worst, unplug it for a minute.
When the router reboots, it will look for the quietest channel number (assuming it is set to auto)
Also try altering the position of your router, away from cordless phones and bases etc.

I checked how many devices i had connected to my new router within 2 months of getting it. 26 devices so far. Everytime i get a new router i change the password and Name to the same as the last router then all the devices dont need changing to the new router
