PC Not Detecting Modem / Router Or Wireless Connections?
Oct 29, 2012
I turned on my PC this morning and I found I could not connect to the Internet. I have a few other computers and devices in the house that are ALL connecting to the Internet fine. I've tried basic things like unplugging /re-plugging the Ethernet cable, resetting router, attempting to set up a new network, system restore, running norton anti-virus to detect any potential problems etc all of which haven't resolved the issue.
I also checked my device manager to see if my drivers were up to date and I found that under 'Other Devices' my Network Controller stated that the drivers were not installed. I'm not sure if this is the issue (considering my Internet was working absolutely fine less than 24hrs beforehand) but I can't search the Internet to automatically find the driver for obvious reasons.
I found a few people suggesting to use the hardware id to find the appropriate driver, any direct link to the driver. My network controller hardware id is below:
PCIVEN_1814&DEV_0301&SUBSYS_25611814&REV_00
PCIVEN_1814&DEV_0301&SUBSYS_25611814
PCIVEN_1814&DEV_0301&CC_028000

When I connect my DSL modem to my DLINK wireless router, two identical DEFAULT connections appear in my wireless connection detection. Both will only connect locally.

[code] When the connection is online, the speeds are fine- the issue is the 2-3 times a day when the connection drops off. The error that we are getting is "cannot connect with primary dns server" however in our attempts to restore the connection we have: [code] is there some issues in the area that we are not aware of?

I have an E4200 and a WD MyBook Essential 2TB. They were working very well for the longest time, detecting a speed of USB 2.0. I had to get a new desk, thus had to disconnect all my devices, including the router. After plugging everything back in, the router only detects USB 1.1, even though the device is clearly USB 2.0.

I purchased the E1200 Linksys Wireless Router on 11/26/12. The router worked fine until today. Without reason, the router stopped reading the internet cable/the port on the router stopped detecting the signal from the cable connected to the modem. I can plug the cable from the modem directly into a laptop and the laptop picks up the signal (using it to write this). I swapped out several DSL cables to confirm it wasn't a cable issue and it does not make a difference. I tried rebooting the router, resetting the router, and yet nothing works.

I currently have a WRT54GS ver 1.0 running firmware version v2.07.1Ran through the whole installation procress as described in the firmware upgrade instructions pdf and it said Successful and hit continue. Hit continue, held the reset button down for 10 seconds then powered off the router for 30 seconds and plugged it back in.My firmware version in the router is still saying v2.07.1, I would assume it should say 4.21.4?

My E4200 works beautifully, and was working fine with the Toshiba 500 GB portable drive that I had on it for a week or so. I tried to plug in my WD MyBook Essential (Passed on the list of compatible drives), but the router is not detecting it. Further, when the drive is plugged in, the router stops receiving new wireless connections. Even if I reboot a laptop that was previously connected, it says that that the passkey is incorrect. When the drive is plugged in, I can't even log in to the 192.168.1.1 - it's as if the router creates a firewall around it and refuses every new connection on every port.

Have a 601 and a system running Windows 7 64bit. Router works great but the computer 1 light goes out when the PC sleeps and does not reset (turn on) when I wake the system. Unplugging and re-plugging the router fixes the issues until the next sleep

My Motorola SBG901 Modem/Router combo has stopped connecting to the internet. I have done all the troubleshooting with Comcast and with Motorola and it is out of warranty, so I will have to purchase a new one.In the mean time, I wanted to use it only as a wireless router connected to my Scientific Atlanta DPC2100R2 modem. Is there anyway to do this? Is there a way to disable the modem in the SBG901? Simply connecting with the ethernet cords has not worked. I connected the DPC2100 to the SBG901 via ethernet cord. My computer was able to pick up a wireless connection but there is no cable connection.

I am using a Windows 7 machine and I'm pretty sure the ethernet cable that I'm using is functional, considering that I'm using it to connect to the Internet right now.I've been trying to get my router going for a while now and I'm pretty sure I've tried everything that the internet has advised. I've screwed around with the card speed, 10 mbps Half Duplex didn't work or anything. I've manually set the IP and related stuff to 192.168.1.x and the works. I've tried to manually run the setup, although that definitely didn't work considering that my computer can't even detect the dang router. I've screwed around with the wiring and restarted my router and modem constantly.

I just got a brand new Cisco 2951 router that has built-in 3 gigabit interfaces cards. We want to add additonal 2 GE EHWIC-1GE-SFP-CU card to it. When it booted up and type show inventory, it did not detect the presence of the card. There was light on at the back of it. I have checked the compatibility on Cisco. The card is compatible with this router. Do we have to install the card with special instructions in order for the router to see it?

My PC usually shows me a list of wireless connections when i click on that icon.Today, however, it is not showing the list and displays the following message instead:'windows cant configure this wireless connection.' no list, so i am not able to connect to my network.i tried setting up a wireless network through wizard but to no avail. I dont know why this is happening. i got a new wifi modem. i cant even blame the new connection alone, because before that my pc at least used to show other inaccessible wireless networks in the list. but today it shows nothing.i have a windows xp.

I have an issue with the Wireless Network. I have an old Compaq Presario V2000 laptop with WIN XP SP3. I formated the laptop OS and installed all the required drivers. I have a Dlink DIR 300 wireless router to connect to the Internet. I switched on the Wireless button; When I tried to connect to my network in Network connecction, I can't see my SSID displayed in available netowrk connections, though I can see others available connection there. I checked, whether my Router is broadcasting the SSID or not, and yes it is broadcasting. I tried with the security type as "WPA-PSK" with AES as well as with "WPA2-PSK" with AES, nothing worked for me. FYI, my room mate can easily access the network on his Sony Vaio CS 15 laptop with any of these two security type.I am fed up . I tried rebooting the router as well as my laptop multiple times.When I manually connect to my network SSID from "Wireless Network" tab in connection configuration, I see a "X" sign over my SSID with a Tower mark.

I have a Lenovo laptop, and all of a sudden the wireless just vanishes.I notice that just before it cuts out, the music I am playing stutters for about 10 - 15 seconds before it happens. when it happens it cant detect any wireless and when i try to trouble shoot the issue it just tells me to plug in an ethernet cable. I check the wireless adapter settings in the device manager and it's working fine, I uninstall and re install. same problem.what I do find is, if I put the laptop to sleep and wake it up, it SOMETIMES works, but I can be doing this for 20 minutes or after one attempt another weird thing is, if I start it in safe mode it works fine. I have tried to look for all solutions on the web, tried everything, nothing works. currently it's working, but who knows it may cut out at any point..

Just re-installed windows on a laptop i got, i got all the drivers installed, but i cant seem to get the wireless card to show up, i know it has wireless because it was my moms laptop before she got a new one. Ive gone to dell support site and literately downloaded all the drivers on the page. Device manager doesn't seem to be detecting the card at all, the dell Wlan utility wont even start ive reinstalled the driver multiple times i even tried the intel site for drivers.
The big problem is i don't know what wireless card it is and its hard to find out because the support pdf for the laptop shows multiple possible cards.

I have attached screen prints in various formats.The machine is a PB Easynote TM01 laptop running Win 7, using built in wireless and for some time I have been exeriencing hit and miss internet/network wireless connections.With my limited knowledge I have managed to identify that two of the network adapters are not showing in Device Mnaager when there is NO connection but are showing when there IS a connection.I think this indicates a faulty (or knackered) network adapter.I now have no connection whatsoever and haven't for about a week.I have plugged the machine into the modem now and internet is fine, but what is the point of having a laptop that can't sit on your lap when it is plugged in.

I have an HP Compaq nc6220 that I just got up and running after an extended stint as a paperweight.It had previously worked great in terms of connecting to the internet via wireless.Now nothing.It let's me go into Wireless Network Setup Wizard and offers to let me set up new networks, etc...But as far as I can tell, it isn't detecting any networks (though they are all around me and detected on other computers) and giving me the option to log in.There is no "Device Manager" option that I can find on this computer, which some forum posts have suggested to other people with similar problems.

url...My wife was using her Toshiba A215-S5837 and all of a sudden, wireless goes out. No networks to be found. I've tried any number of drivers I could find. I have also tried using the driver as suggested by many places (including the previous thread), found on the CZ site. No luck. I just tried safe mode and updating to no avail. Though Windows 7 is not kind about letting you install a driver initially. I uninstalled, and plug and play took over so I was forced to do it via update.

I have a very basic WLAN setup with a 2106 controller and 3 (will be 4) 1140 APs.As part of securing the network I have been testing the rouge detection. The system has no trouble detecting and shutting down honeypots. I would like to also automatically shut down Rouge on Wire points. The system sees my test AP just fine. And I have it completely open (no security). But the system never detects that the rouge is on our network so no action is taken. I can connect just fine to the test AP with no encription using DHCP and communicate with everything on the network just fine.Is there some setting I am missing that allows the APs to detect that an AP is on wire?
