LAN Disappears When Using Docking Station
Aug 19, 2012
I'm using an HP Elitebook 6930p with Windows XP and an HP EN488UT docking station. When I use the computer by itself the Network Connections shows "Local Area Connection 3 Connected Intel 83567LM Gigabit Network Connection" and I can connect to the internet. When I am in the docking station, I can also see this connection, as long as my notebok is open when I start up. However, if i start the computer with the lid closed (I just want to use the external monitor, not the notebook monitor) that network connection does not appear and I cannot connect to the intenet.

I have a Latitude D820, Windows XP, SP3. At my office I have a regular docking station but at home I have a D/Dock docking station. When I dock the 820 at home the Broadcomm network card works flawlessly. When I dock it in the office, it will occasionally work but most of the time the link light and data light on the docking station are on solidly and XP reports that the cable is unplugged. I have tried two different docking stations with identical results and also tested the cable by plugging it into the docking station that holds a D810. With the D810 it worked normally.

I have a Latitude D400 laptop with docking station. I left on a trip for a week and came back to find I cannot connect to the network through the docking station. I can however connect if I plug the ethernet cable directly into the laptop. Is this a hardware problem with the docking station?

I have a HP 6530b Laptop, and on-board Broadcom NetLink Gigabit Ethernet adapter.When I remove my laptop from the docking station, I obviously lose Network connectivity, however, when I replace the laptop back (or even just plug in a cable directly), I cannot reconnect to the network until I reboot.When I open Network and Sharing Center (Win7), and click change adapter settings the adapter is missing from the list (after i have removed laptop from docking station).

I am using a wireless connection via router to access internet at home. When my Dell Latitude E6510 Laptop is not on the Dell Docking Station and I'm using as just standalone I can access my wireless connection easily, no problem at all.However, when I attached my laptop to my Dell Docking Station, I can not access my wireless connection. The wireless connection is found, but when I click connect to network, I get "Windows cannot found network". When I remove the laptop from the docking station, I find the wireless connection and connect perfectly and it works normal.I am using Windows 7. I can connect to internet with straight wire going to docking station easily, but no wireless connection found when laptop is on the docking station. I work from home and use the docking station for two monitors for doing my job. I have struggle with this problem for two weeks now. I don't see anything on the docking station that's preventing me from access my wireless connection.

I cannot utilize my Ethernet connection when my Dell Latitude D630 is connected to a docking station. I have tried this on two different docking stations. I also have another Dell laptop that I have used in the one of the same docking stations and the ethernet connection is fine. I'm looking for assistance to troubleshoot this (even just determining if I can replace the connector and how I determine what type I need)

I have a pretty old Linksys WRT160Nv3. I tried support from them but I was told my router is too old to receive free support. My router is connected to a comcast modem (Motorola).
Two days ago I tried to connect to the internet with my iPod and had no luck, the same went for my phone and my roommate's laptop. When I went on to the computer with with the router I was it was connected to Network 4 our local network and couldn't find any other networks. Our router came with 'Network Magic' so I opened that to see if our existing network showed up there, but only it's settings were there...it's like the computer tried to erase our network. I reset the router and re-made the network and this solved the problem for the day and most of yesterday.
Yesterday evening, I came home to the same problem. I did the same thing I ddi the first time, but instead of reseting the router before I did anything I skipped to re-installing it. I'm here because this happened again this morning, and before I go and set up the network again, I'd like to know what I'm doing wrong and what I should do. I even got a new anti-virus because I was afraid there might be a virus on the the computer making it act weird but I haven't been able to complete a full scan yet.

We are running about 75 computers in a network. We have a server here where all the clients have a shared folder that we map for them, but as soon as they restart their laptop, the map drive disappears. We are running a script that we tested on a network where the laptops were linked with a cable, but as soon as you switch over to wireless it disappears.

I have a Windows XP SP3.I bought this machine used not too long ago, it came with a legit fresh install of XP and all the drivers. And it's been running in great shape until this. I'll retrace my steps as best I can.I was on the internet and my connection was still connected (Completely, not limited) but my browser wouldn't surf. I naturally restarted my router, nothing changed. So I restarted my computer. When it came back on the Wireless didn't boot up like it used to. I checked my internet, it was fine. My laptop was running fine on it.Now as I try to figure out whats wrong, my "Wireless Network Connection" is gone completely from my computer. AND the Wireless isn't on my device manager anymore?? I installed another USB wireless stick (which I used on my old desktop) and it's working ok but I feel like my connection used to be so much better which the ASUS wifi instead. I un-installed the driver, and re-installed. [code]

Having a strange problem that just started this week and got worse this evening. I have a RV220W that is feeding my network. The RV220W sits behind a broadband modem and acts as the DHCP for the network and those computers access the internet that way. Anyway, tonight started an issue where the the RV220W just disappears. Becomes unpingable. I recycle power, and within anywhere from 5 to 10 minutes, it's gone. No longer pingable. Even if I plug a latop directly into it.If I power cycle the RV220W it comes back and I can ping it and access it and its settings. 5 to 10 mins later, I again lose it. Nothing was done. Its been working fine for a few weeks. Had a similar outage last Tuesday, but a recycle of everything brought everything back into line. After I lose connection to it, the lights I expect to be lit remain lit.

I'm currently using a Lenovo V360 and my issue is that my computer, which connects via wi-fi, disconnects from the network randomly. The network will be completely removed from the list of available networks. The other networks available will still be visible. I tried turning off the wi-fi button on my laptop and turning it back on, but the list of available networks still does not include the network I was recently connected to. The only way to see the network on my Lenovo is to restart the computer. The connection works perfectly after I restart. It is definitely not the network's problem because I am still connected to the same network with my other laptop. If necessary, my laptop runs Windows 7, my router is a D-Link, and the encryption is WPA.

Every day or two my landlord's router just seems to disappear altogether . just seems to turn itself off randomly. Unplugging to reset results in good, clear signal for a while, but the problem always comes back. It affects all connected machines (not sure if it makes any difference if a macnine is connected via wire.)

I've been having this issue where my wireless network completely disappears from my computer and it requires a restart to fix.I know for a fact that it is not my modem/ISP as my iPad still connects just fine to the network.My network disappears about after 10-20 minutes of being logged on.

win xp I work at a junior high school. A lot of the computers are part of a work group so they can share printers.
I'm having problems connecting to a printer. It has worked for a long time, it's still my default printer, but when I try to access it, it gives me a spooling error.
Now here's why I think it's a network problem.I can't access the main computer's network location (the one hooked up directly to the printer). All the other computers come up on the networkjust fine. And the one in question is only able to access very few computers in the network browser. let me simplify:
computer A/ brother printershared computer B/no longer sees A on network A/ sees only a small portion of other computers on network B/ sees all computers but A
Again, I don't think it's a spooler problem. It probably gives that error because it's a default printer with a lost connection.

Every day around the same time the SSID for my wireless network disappears. I'm using a Netgear wnr2000v3. Prior to this I was using a Linksys router, which did the same thing... only more frequently (2-3 times a day).Between smartphones and laptops, there are about 6 devices connected to the network. They all lose their connection and cannot find the broadcasted SSID when this happens.Because it happens around the same time each day, it makes me think that it has something to do with the DHCP lease, which is 24 hours. Just a thought, as I don't really know how that works.

I have an i7-2700K system with MSI Z68A-GD80 MB running on Window 7. Awesome system. Only one issue. The Network Adapter section keeps disappearing from Device Manager, causing my ethernet to fail, no lights on either of the RJ45 ports with cable plugged in. All of the latest drivers are installed. I've Googled it and see others with the same problem and have followed the "temporary" solution - shut down the system, unplug it from the power supply, yank the memory out, press the power button with PSU unplugged to "bleed" the caps (or use the pwr/reset button on the MB before shutting it down), let it sit for several minutes (it takes mine at least an hour, so I'm thinking the system needs to be completely cooled down) and then put it all back together and turn it on. Network Adapter section shows up again, Ethernet lights return, internet works again.
This works until the next time the system shuts down and then I have to do this all over again. Extremely annoying problem. I'm not sure if it's a faulty MB or if there's an actual permanent fix.

I am having a setup problem with the RE1000. When I plug it in, my laptop is able to see it, and I'm able to access it and attempt to set it up. However, once I tell it how to connect to my main wireless router, and it attempts to log onto my wireless network, the RE1000 disappears from my list of networks. My blu-ray player also cannot see it.

I just bought a N750 DB router. On boot up, the 5Ghz side will show up for about 20-30 seconds and then it just "disappears". I was even able to connect to it @ 300mb with my laptop. The 2.4Ghz shows up just fine.

Can I connect 2 or more wireless repeaters to the same wireless base station signal to extend wireless coverage? I.e. The base station is located in the centre of the building and the signal covers the middle but not the extreme end of the building. I would like to add a repeater on each opposite sides of the signal's reach so it covers the complete building. I can't use LAN cable and the building has different electricity supply to the 3 different part of the building so can't use the mains to carry the signal. Is this possible using wirless repeaters or do I have to use wireless bridge units to connect to the base station and then output with wireless access points attached to the bridge unit to extend the wirless signal?

I have an Asus Model U56E. Recently the wireless has been disappearing whenever I turn off my laptop. What I mean is that when I turn on my laptop, the wireless doesnt seem to exist. I go under device manager and all I have is the eternet and my bluetooth device. About 85% of the time, when I go under "action" and click on "scan for hardware changes" the my Intel(R) Centrino(R) Wireless-N1030 will show up along with the Microsoft Virtual WiFi Miniport Adaptor and I'll get my wireless back. However, when my laptop turns off, the same thing happens.
In addition, my fn F2 button no longer seems to work. I'll press on it and majority of the time my light that signals that the wireless is working does not turn on. Most of the time it stays off whether or not I am connected to the wireless
This is what I already attempted to fix it, based on googling for answers:
1. Under the properties of my wireless and miniport adapter, I went under power management and unchecked the box that says "allow the computer to turn off this device to save power"
2. I went to my laptop's power plan and changed all my wireless adapter settings "power saving mode" to maximum performance for both battery and cord
3. I went to the intel website, had it look at my laptop wireless system and followed their recommendation of installing an updated wireless software thing. All that happened was that it told me to disable my old wireless and then install it. However, even though I followed their instructions, it continued to repeat the same message. I had to perform a system restore to get my old wireless back
4. I disabled wireless console 3 (by Asus) under programs and it seemed to work. My laptop was getting connected whenever I turned it on. However, the next day my laptop updated itself (b/c of my system restore) and I am back to the same situation except my wireless console is still disabled.

My 'main' Wifi SSID will just disappear and you can't connect to it. the guest account will still show up. computers/devices that are already connected will stay connected and will work fine, but anybody reconnecting will not be able to. Only solution I've found so far is to unplug and replug in my router

I have two Cisco 4506's running cat4500-ipbase-mz.122-50.SG3.bin. Periodically, when attaching a new workstation to these switches the Mac Address of the device disappears off the port when the device is connected or the port is configured. The only way to correct the issue is to do a hardware reset on the blade or reboot the switch. After resetting the blade or rebooting the switch the devices will start showing up on the port and connect. This does not effect devices that are already connected to the switch, just newly added devices
Both switches are populated with WS-X4148-RJ45, WS-X4148-RJ45V and WS-X4248-RJ45V blades. It doesn't matter which blade the new device is being connected to. I believe that this may be a "Bug" but have been unable to locate one.

I've got a machine on my home network running Windows Server 2012 (Based on Win8).The problem is, my taskbar disappears completely.When I minimize an application rather than minimize to the taskbar it simply closes the window as small as it can as if the taskbar never existed (see photos at bottom).
The problem first presented itself after I accessed the computer from outside my local network I'm using a Linksys router and mapping to the server IP, port 3389.After a restart the problem goes away, I will update when I have more information on how frequently or what may trigger.

if the network i'm planning on will even work so i drew a picture on my project (attached). All cables will be gigabit compatible as will be the switches. The reason i will have 2 switches is because they won't be in the same building. The uppermost switch will be physically next to the router to enable me to have gigabit connection between the DiskStation and the PCs/HTPC without having to change my router (in fact can't change it due to special firmware for my internet TV).

We would like to install a wireless network throughout the station. Currently we have a wired network with 15 PC's and are looking at obtaining tablets for our squads and apparatus. The station is quite large and is divided by the vehicle bays.I'm thinking that we will need multiple access points throughout the station. I am familiar with setting up one wireless router but not with multiple access points.

I have the Air Station WHR-G300N. I just moved here from CA, I was on Verizon and now trying to use it on my girlfriend Cox system I can't get it to operate correctly.
Her PC system stopped having internet connection after about 2 weeks(running on the router) and going with Cox's reboot procedure of eliminating the router it can back up and seems to work fine as soon as I hook it back to the modem it stops.
I have unplugged all cables waited 30 seconds on both systems a couple of times. The lights are on the modem and the router.

I was wondering if it is at all possible to set up a DIR-655 as a wireless base station for any router (specifically a netgear wrg614 v10). I've read that the DIR-655 can be set up as an access point, but with my current situation it's not currently possible.If this is not compatible with this specific netgear router, is there any other solution besides having to purchase a dedicated access point?
