Vista - Unable to add WiFi network to Favourite Networks on Vista 64 bit

Hi, for some crazy unknown reason, today when I logged onto my computer, there seemed to be a probelm. My WiFi did not connect automatically to my home network which I had recently added as a favourite network. I typed in the password and it connected. I then went to my network list and noticed that the network had been removed unknowingly, after noticing this, I then tried adding the network manually and guess what, it showed me access denied.

Why is this happening? I am the system administrator and it is still showing me access denied. Please help me, reply ASAP

Hi MrElectrifyer,

The first thing that comes to my mind is "hacked". If someone managed to get access to your router (WiFi or WAN) and changed something in there, your Windows detected that change and stopped it from connecting automatically... maybe. It never happened to me nor haven't heard something like that either but if I were an OS, that's what I would do. Try logging on your router and look for changes specially in the wireless part. If you can, copy your router's NAT and static IPs configurations and restart it with a clip or something and then re-configure it using a stronger password of course.

Cheers,

That is not possible because if someone managed to connect to the network, my software Cisco network magic Pro 5.5 will show it as an intruder on my network map, but currently, there is no unknown device/intruder. I am using a D-Link DIR-615 Router. What is preventing m from adding a network to my favorites? Please tel me any possible virus or windows function the might be casuing this and how to deal with it. Thank you, and by the way, I performed a full system scan using my AVG Internet Security software and it found no infections

Yeah it doesn't sound like a virus or malware... why would there be a virus that only prevent you from connecting automatically to a network instead of being around destroying your files.

Back to your problem. Are you sure you don't have your network invisible on your router? D-Links have several options to protect your network. First, enable the SSID Boradcast on your router, re-connect and try to save the network. If your PC still doesn't allow you to, then change the network's IP address (i.e. from 192.168.0.1 to 192.168.1.1) and network name, restart your computer and try again.

Tell us how that goes.

No my network SSID is not invisible, and besides, if it were, that would not prevent my computer from auto connecting because it will already have the SSID and the key, that is all it needs to connect to the network. I have a static IP address and it happens to work everytime I enter the key (in order to connect). PLEASE WHAT COULD BE CAUSING THIS, IF THERE IS ONE COMPUTER EXPERT OUT THERE, I COULD REALLY USE YOUR HELP RIGHT NOW.

Is your router setup as ad-hoc? If that's the case, it's Window's fault. Some time ago (specially Vista), Windows begaun treating the ad-hocs wifi networks as insecure and stop you from being able to store them or at least loose them after a reboot.

If this is the case, a quick and nasty way to solve it is to create a xml profile with your connection settings and a scheduled task that triggers at startup (with a 1 minute delay) that fires up "netsh.exe" with the argument "wlan connect name=xxxxxxx" where xxxxxxxx is the name of your wireless LAN.

No offense, but What you are saying doesn't make sense, an ad-hoc network is one that doesn't use a router/base station. My router can't be set for ad-hoc networking

No, an ad-hoc router is commonly known as a "repeater" and that's exactly the outstanding feature from D-Link. Is just that is not always called like that. It depends on which build is your router (DIR.615 has 3 different builds) and firmware but you can set it up as a Ad-Hoc just by disabling UpnP and DHCP. In that case, It would be working as a repeater (which just extends your internet connectivity without managing your IPs and stuff) and that would be giving you trouble. Did you try reseting the router? Just insert a little clip in the little hole in the back of it for 10 seconds or so until all the front leds turn off and back on.

The current firmware of my router is 2.23 and the hardware version is B2, how can this hel in solving my probelm? Other computers in my house don't have any of this problem connecting, so I don't c how myne alone is having the problem.
