Okay I need help. My PC decided it wasn't going to connect to the internet any more. Here is what I've done. Tried multiple wireless adapters, multiple wireless routers, and multiple internet connections. My PC will connect to a wireless router but it will never grab an IP address. My connection always says "limited". Under my connection properties the status says "IPV4 connectivity not connected". Now here is the twist. I can manually enter an IP, mask, and gateway and then my Internet connection is restored...but the connection is still limited and "not connected". When I run the trouble shooter on network connections I get this "problem found". "Windows could not automatically detect this network's proxy settings." Whats going on?
Is the network type set to public and defaulting to public on new connections? This can cause limited network issues and can be a pain the fix. Check in network Ans sharing center. If you chose public on a new connection and accidentally ticked the 'always choose this option' box you will need to download a fix from M$.
Under networking and sharing I see "View you basic network information and set up connections" under that it says "Unknown". It should show active networks but there is no useful information there. But under windows firewall settings there are settings for private and public networks. It says I'm connected to a guest or public network. Private network is not connected. I tried to repair the TCP/IP stack in an Admin command prompt. Under the IPv4 part I get a Resetting failed access denied.
Assuming that the public network is still the problem another way to check is in the registry. HKLM > Software > Microsoft > Windows NT > Current Version > NetworkList > Profiles Under here are all of your network profiles. Now there may be loads of these as you have been setting up a few networks with all the adapters you have tried but you could delete them all and try to connect again to create a new one if you can't find the one you want. There should be a value called 'ProfileName' which should display your network name and mean that you can find the relevant one with the data being whatever you called your network eg 'bfun.local'. There should then be one or two DWORD values depending on the network type. If it is set to public you will only have 'Category' and it will be (0). If this is the case change it to (1) or (2) (one is work on is home, cant remember which is which) and then create a DWORD value CategoryType and set this to (0). You could also try this fixit from Microsoft which will make the option reappear for the network type and make sure that the tick box isn't checked to apply to all networks. http://support.microsoft.com/kb/2578723
I've pretty much tried that MS solution. I'll try yours tonight. If I spend anymore time on this it will probably be faster to just reload Windows. I did download some audio control software the day before. Maybe it rooted my machine. Shutting down the network would be the opposite of what most roots do but you never know.
Actually if I am honest the fixes I am suggesting didn't work for me last time I saw this problem either. The laptop worked on the employees home network but somewhere down the line she must have joint a new network, clicked public and ticked the always choose this option box. This meant that I couldn't get her VPN connection working as it won't let you setup a VPN on a public network. The other weird thing about her laptop was that when you tried to connect to a new network it would make 100's of profiles for it if you left it long enough. In the end I had to reinstall Windows for her just so that she could connect from home.
My wife's laptop from work has this same issue. If you find a solution short of formatting the computer, please post it.
uhm... this probly isn't related but I had some crazy internet issues a bit ago thinking it was a broken router or modem/ bad connection or something. turned out windows just didn't wanna play nice with my SSID. You might wanna simply try using a default SSID with no encryption for a minute that worked for me than I worked it out from there. It was pretty simple really and all this time I was replacing h/w and thinking it was some complicated s/w issue when no, Windows was just bein a dick as always. Anyway most of my issues seem to come from my SSID so you might just want to check it out! Like one time I changed it than turned on a computer that wasn't changed and it would connect so I didn't notice it at first but sooner or later it just stopped. I even updated the SSID and it wouldn't work or something like that, nothing would until I defaulted and worked my way up updating the SSID on all the connected machines at once... oh and the stupid Wii won't accept anything with an underscore (this, _).
This bullshit is exactly why I made my godlike PC last year. I even started using my "main" PC as a VM in my real PC. I do VM snapshots so I can roll back my problems in under 2 minutes. Troubleshooting is a waste of time. It cost ~$1400 but it's much cheaper than a Delorean.
Bfun does networks for a living and he already said he tried it wired which completely negates any SSID issues. M$ really cocked up by letting you tick a box to default to public networks. Have you tried to download and run the Fix It from the link I posted Cmdr?
Re: Re: Sonu's n00bish PC questions I would find it a nuisances using a type 2 hypervisor to run a main home desktop. Waste of resources too with another full OS running underneath.
My brothers laptop has been doing this for a while now. He didn't tell it to. Anyone know what it's doing and why? It's finished doing those checks. Now its having extreme difficulty starting.
Check disk is running and his hard drive is toast. He didn't have to tell it to run check disk. The operating system will do it when there's a problem. If you can get back into windows, run HD Tune, and tell me what the "health" tab says. I can practically guarantee you it will throw up SMART errors. http://www.hdtune.com/
No more Kingston SSDs for me I guess. The replacement drive they sent me that I'm using in my laptop has also gone bad. It's having issues resuming from sleep. I'm often getting a black screen and the laptop is unresponsive until I reboot. So basically I went from blue screens with the original drive to black screens with the replacement. They're upgrading me from an SSDNow to one of their HyperX drives with the replacement, so hopefully that will actually work.
Hyper X is a pretty nice upgrade. Being sandforce based I'm not sure you can bet on it being reliable though... Most manufacturers have ironed out the firmware kinks now. I'm considering buying a Sandisk sandforce based drive just because they are so cheap here. Sandisk are apparently one of the more reliable brands coming later into the scene like Intel. With a 240GB going for $170, it seems like a great deal. My 240GB Vertex 2 has gone 2 years without issue, although it was a replacement for a 200GB Vertex LE (the original Sandforce drive) which died after 2 weeks. Sandforce drives still perform admirably, doing particularly well in Anandtech's new 2013 stress test which seems like a really good real world indication of a very high workload. The only issue is as I said, the reliability factor. The only other drive I'd want is Corsairs Neutron GTX. Anand have shown it to offer much more consistent write performance compared to Samsung's 840 Pro series and it is priced the same. At $260 for 240GB here, I'm not sure if I can justify the $90 premium over the sandisk 240GB sandforce drive... Maybe I'll just hold onto my Vertex 2, it's still fast enough to be honest...
The Hyper X seems to be working well. No blue screens, issues resuming from sleep, or slow posting like I had almost immediately with the other two drives. Also, Kingston has good service. They sent me the new drive by FedEx overnight for no charge. It was only a couple of days I was without a drive. I might buy an SSD from them again, but I would probably stick to their Hyper X stuff.
I'm getting more used to fixing laptops. If you have to disassemble one, the trick seems to be to get a bunch of ziploc bags and a permanent marker or label gun, and bag and tag everything as it comes off, right down to which screws go where. It also helps to have a smartphone handy to take pictures of anything that looks complicated to put back together. I've done it this way a few times now, and they go back together pretty smoothly.
