I am a teacher in a computer Classroom. We are on a school network and certain students abuse the internet privalages. Is there a way for me to restrict the internet for a certain computer in the network besides unplugging an ethernet cord?

View 4 Replies View RelatedI currently own a Lenovo Thinkpad x201 Tablet Laptop.The issue is that I randomly lose internet access after usage for some time. I've determined [but not limited it to] that the computer heating is causing the computer to automatically disable the connections. I've looked at the Drivers and have found that one of the Drivers disables itself and will not re-enable when I try to enable it again. When I try to reboot, it stalls on the Shutting Down screen indefinitely [I must force restart].

I've checked the BIOS, but I haven't found much of anything. After tampering for a while with it, I received a BSOD. After trying to boot it back up, I got the "a disk read error has occurred" screen and had to send it in... at which point they reinstalled the OS, wiped my hard drive, and sent it back.
I have a central cisco SG200 26P switch, with about 20 ports going off to other network switches, and individual computers around the building.I need to keep the LAN functionality of the network, but I need the majority of the computers to not have internet access. But I also need to be able quickly re-enable internet access for a particular computer connected to a particular port if required.
View 3 Replies View RelatedI no longer have internet access from my home network ONLY on my desktop computer. Everything was working fine as always - then while I was in my Network and Sharing Center, and clicked on my ethernet connection, 'Local Area Connection 3', I accidentally disabled it. No big deal I thought, so I re-enabled the connection. Except for some reason, my connection is all screwed up now. The name of this connection was and always has been 'dkm2' and now it just says 'Network', with no internet access. I have unplugged the cord and plugged it into this laptop and it immediately recognizes 'dkm2' and connects flawlessly, so I know the problem is on the desktop computer's end, and not the cable or router. I have tried reinstalling the ethernet adapter, as well as reinstalling/updating all drivers for it.The network diagnostic tool turns up with a message that says the connection between either my ethernet adapter or router and the Internet is broken. No matter what I seem to try, I can't get my connection to go back to it's normal 'dkm2' connection and stop giving me a generic, disconnected 'Network'. I can't figure out what could have changed. All that happened was the disabling and enabling of Local Area Connection 3.
View 9 Replies View RelatedThere is a page in the DIR-825 that logs your computers IP and the other IPs it is connecting to. I was wondering if there was a way to disable that function on select devices? My handhelds and legitimate computers that should be on the internet are filling it with spam and it is hard to check for unauthorized users on the network. If that is not possible, then would I be able to completely disable the feature?
View 1 Replies View RelatedI purchased a WNDR3400v2 probably around two months back and since then I haven't had any issues with it. Now, I like to keep the security setting on WPA2-PSK for the security but my brothers and my own Nintendo DS don't support this security for connecting. So, since my previous router had a guest network, I decided to activate and deactivate that network with no security when it was needed (Half hour or less), and I haven't had any issues until doing this with the WNDR3400v2.
Basically what happens is, after disabling the guest network again, no wireless devices can connect to the router... PERIOD... Upon trying to connect it also says "You are unable to connect) right after it verifies the password. I spent a few hours trying to fix it but I haven't gotten anywhere really..
What I have tried-v
-Resetting the Router
-Powercycling the Router
-Resetting it to factory defaults and restoring previous settings
-Enabling and disabling the network
-Deleting the original network saved on the computers and connecting as if from a new network.
-Also tried restarting my computers
-Updating the firmware (For some odd reason I couldn't find any firmware last week..)
I researched it a bit and found some solid leads, but nothing that fixed the issue. The only "Fix" I could find was disabling the security and leaving it open.. Which I would prefer not to do for obvious reasons...

I am aware of the PSP issue and have turned off the option to allow the computer to turn off the adapter and have set the power settings to the highest settings for both battery and plugged in. I have messed the routers security and the computer will not connect unless I turn off the security entirely. It connects but is slow. Anything else and it will not connect at all. Regardless, it can always detect the network without a problem and shows signal strength of Excellent (full bars) even when it is running slow. It works great on a cable or with a wireless usb adapter. I am positive that I am entering the password correctly as i have done this many times now. All other wireless devices in the house connect without a problem including her old Dell laptop.I have updated all the drivers (including the adapter) and keep current on all the Windows updates.when I run the ipconfig /all it lists all my wireless adapters and the blue tooth as "media disconnected". Not sure if that is referring to not being connected to the network or something else.
Basically, my issue stems from the latest Boxee firmware from 2 weeks ago, that since then, its been causing my DIR 655 to reset itself, thereby disabling my whole home internet. It eventually turns back on again after a while, but the process doesn't stop.Basically, my DIR 655 is connected, hard wired to my boxee. I also have a NAS 323 hard wired to my router. I've had this setup on my boxee, reading all my movies/shows from my NAS without any issues for the past 10 months. Then the firmware from 2 weeks ago on the boxee started to cause my router to reset. I thought it was a hardware router failure, so I bought another of the same model to try that out, same thing happened though. When I rolled back my boxee firmware to the previous version, it no longer causes my router to reset.Now, besides me trying to figure out how to correctly block the boxee from updating on the router. Is there anything I can do on the router to tell it to prevent it from letting the boxee forcing it to reset? I'm on High Speed DSL. My internet provider modem is acting as a bridge to my DIR 655. Its been working fine for the past 10 months.
I've also done the following:Ensure DNS IP addresses are being filled in under Setup/Internet/Manual? You can find thse under Status/Device Info/Wan section. Turned off ALL QoS Turned off Advanced DNS Services if you have this option under Setup/Internet/Manual.Turned on DNS Relay under Setup/Networking.Setup DHCP reserved IP addresses for all devices on my router.Ensure devices are set to auto obtain an IP address.I have Set Firewall settings to Endpoint Independent for TCP and UDP..
Basically, I've put my boxee back to my previous firmware, and this doesn't cause my router to reset and disable my internet. But I don't get how/why a firmware update can trigger my router to do this?

View 6 Replies View RelatedSince a while back my internet access dies intermittently. I have a bunch of computers (mine, the kids, media stations etc.) in my network and one of them is configured to run two different instances of Windows: One for serious stuff (like work) and another for leisure. They're both Windows 7 Ultimate x64 instances and I use BootIt NG for this dual boot setup. Now, when I run the "work" instance I have no problems whatsoever but when I fire up the "game" instance internet dies off at irregular intervals, usually once or twice per hour.I've tried the usual stuff like resetting the IP stack (with ipconfig) and reinstalling the network card driver but the only thing that facilitatess is restarting the VDSL modem/router. I have also replaced the VDSL modem. What's really queer is that all other computers also looses internet access when this happens. And, if this wasn't strange enough, I never loose my WIFI, just the cabled network.

View 14 Replies View RelatedAfter recently setting up a new computer, my entire network seems to randomly loose internet connection. The interval between connection losses is as short as half an hour but it sometimes goes several hours without dying; the connections is lost for anywhere between 30 seconds and 20 minutes each time it dies.The new computer is running Windows 7 and is using a Roeswill USB wireless adapter, but I have tired it with a wire and the connection still dies. I am disinclined to believe that this is caused by a virus simply because this is a brand new computer that has had only minimal use; to be on the safe side, though, I did do virus scans with multiple programs, however, I did not find anything.When the connection is lost, a yellow exclamation appears on the task bar's internet access icon. If I check my available networks, my network still shows full strength. I have tried disconnecting and reconnecting but nothing happens; I don't get any "failure to connect" type errors nor do I get connection back. I have also tried physically removing the adapter/wire and plugging it back in, but that doesn't do anything either.
I am under the impression that the new Windows 7 computer is doing something to temporarily kill the entire network, but I don't know what.For the record, my modem is an old Motorola and my router is an old Netgear. Both are quite a few years old, but I don't think they are the problem as my internet was fine before I added the new Windows 7 computer. There are wired computers and wireless computers running XP, Vista, and 7 also on the network.
We have a fairly new (about two weeks) wirless network set up in our home consisting of a Netgear modem (with wifi, which I have disabled) connected to a Belkin N wireless router. Our ISP is Optus.
My laptop (which is running Windows Vista service Pack 2) was connecting fine since we set it up until about 2 nights ago. Since then, it has had trouble connecting to the network (windows tells me it's taking longer than usual) and when it finally does, I have limited or no connectivity.The internet works fine when the laptop is connected directly to the modem, and if I unplug the wire, it stays connected to the network wirelessly for several minutes before it drops the signal.
At first I thought it was because I was using the laptop at the back of the house (with the modem and router being at the front), perhaps the signal experiencing interference, but no matter where in the house I try to connect, it has problems.I also tried updating the drivers and uninstalling/reinstalling the drivers for the adapter in the laptop, with no luck.
P.S.

I have 2 computers on a network, and 3 devices that use wifi on the same network. Basically when ever computer A is connected, every single computer or device on the network runs extremely slow, if at all. I get anywhere between 1200-2000 ping on pingtest with 2-60% packet loss. Even the speed on the "infected" computer A downloads extremely slow. I'm at a loss for this problem, everything runs slow and its because of the one computer connected to it. I have virus software on this computer, but its not the best so i'm not ruling out malware or viruses right off the bat.

The internet modem runs to a router (Dlink dir615) then to a switch (or hub, if you will) and then to the 2 computers. The entire problem is solved by unplugging computer A from the system. But other than that I have no alternative.
Looking at getting an older second computer onto the internet. We have a wireless connection on the primary computer so I was looking at the TP-Link TL-WN321G USB network adapter, or the TP-LINK WN350GD PCI network adapter.The end goal of course is to get the old computer onto wireless, but not sure what the best way to do it is. I'd think the motherboard would accept the PCI card though we do somewhat lack USB facilities. The computer uses a USB hub which I'm not sure if it would impact on internet speeds at all.

However the 5 wireless computers all get 16mbps which is pretty good for them. Windows tells me that its a firewall issue and I currently can't use two programs, spotify and steam. They both have firewall issues, even if I turn off my firewall which is the windows one. I also have avast, and when I turn that off, still no good.

I should add that I have recently re-installed Windows 7 so on this fresh install it has never had decent internet speed. Which I thought was weird.. I have basically had these problems since the fresh install. All of my drivers are up to date.

So, recently I've been trying to set up Port Forwarding and I've been having trouble getting sites like canyouseeme.org to see the port. After speaking with Tech Support at my ISP, they had me disable some of the settings in my SURFboard modem in order to deactivate the router side of things to get it act only as a cable modem. However, my port forwarding is still not working.
Here is a screen shot of all the pertinent screens of my SG6580 properties, and what they had me set. if I have properly configured the modem to not interfere with my other wireless setup so I can at least rule this out as what's blocking my port forwarding?
