Random Loss Of WiFi Connection?

Apr 29, 2011

On these occasions, while watching Hulu on my HTPC, which only connects via WiFi on my Router (Cisco E3000), the movies were interrupted by a loss of connection, indicated by the white tray icon turning orange, and when expanding it's menu, the connection bearing the name of my network had disappeared.On the first failure, the flashing light on the network adapter (Belkin F5D8055) continued flashing as usual, but the steady light was out, until pressing the connection button. The second time around, both light remained lit as normal, but in both instances my network connection on the network adapter's tray icon had disappeared. Using the WiFi's network adapter's connection button, and the router's PBC button didn't solve the problem, nor anything else that I tried.Since the WiFI connection is primarily for internet access, rather than connecting computers, and that shutting off my desktop doesn't usually effect the HTPC's internet connection, it seems obvious that the connection is managed by just the router, adapter and HTPC, so I fail to understand the relationship between the vanishing network and the loss of internet connection.When these failures occurred, they only lasted for ~ 10-15 minutes, and then were restored on their own, with no more apparent reason than the outage had. So far, this is only an annoyance, but I fear that it is an omen of greater problems on the horizon, and I have no idea of how to isolate the origin of the problem..

Network Connection Blockage / Loss / Lag

Nov 27, 2009

I had my Windows 7 running for 3 days with no issue, perfectly i must add, but up from Tuesday I'am struggling with really critical network issue.

I'am really turning on this forums as last resort, and I'am closer and closer to roll back to WinXP (which i really don't want...). But let me begin describing the problem from the beginning.

Some hardware specifications:

Windows 7 x64 7600 Polish Version

Motherboard: Asus P5QL Pro (with Intel chipset)

Network adapter: Atheros AR8121/AR8113/AR8114 PCI-E (On Motherboard)

Connection: Wire, Ethernet, straight to Modem

Modem: WebStar EPX2203

Antivirus: None

Firewall: only default Windows firewall

- On Tuesday (24.11) morning (+1 gmt) I've installed drivers to my Network adapter which were in Windows Update.

- While playing Team Fortress 2, i started having really akward lag. I was able to hear and see everything around but i couldn't react. Then after couple of minutes my net got disconnected, loosing connection to the internet for a brief moment (up to 1 minute)

- I've blamed my internet supplier but the lag continued throughout whole day. Even during phone session on Skype it managed to last 5-30 min, finally ending with short net disconnection. Steam games weren't the only one affected, as while playing Borderlands i have also suffered from a lag, same type of lag like in TF2 (heard, and saw but couldn't do anything in-game)

- Until today, I've reinstalled (that is uninstalled adapter then installed, also in Safe Mode) drivers for my Network Adapter many times. Forcing Windows to not install his own, but only that which i chose, picking from all 3 drivers (from newest to oldest) which are supposed to be supported by Windows 7.

- I have also dabbled with Task Offload and unchecking IvP6, turning off Windows Firewall, but none of these brought any solution.

- Now I'am after fresh reinstallation of Windows 7, thinking that will resolve everything. But after i've installed every needed driver (for Graphic Card, Intel Chipset, HD Realtek Audio, updating DirectX, without updating Windows at all) and launched Team Fortress 2 to test out if lag is still present i've sadly encountered same as pre-reinstall of windows7.

Any ideas?

HDMI To TV Connection - Loss Of Picture And Sound

Sep 10, 2012

I have a Acer aspire 5536 laptop with ATI Radeon HD 3200 graphics card which i connect to my Pansonic TX-L37G20B LCD Tv via the HDMI output on a regular basis to watch films etc. I have had no problems with the connection since the day i bought the TV and have been happlily using it for the last 2 years.

A couple of days ago i connected the laptop to TV as usual and changed to the correct HDMI channel and got nothing. I disconnecetd the lead and reconnected but still no picture or sound on the TV. I tested the HDMI cable and Tv input by connecting the lead to my XBOX and it worked perfectly.

When i connect the lead to the laptop the screen goes blank for a second and i hear the connection sound as normal however no picture on the TV.

I have checked the display settings and the TV is listed under monitors. I have tried all settings eg extend display, duplicate etc.. and it appears to work correctly but i cannot get a picture or sound on the TV. I did think maybe this problem was due to a recent windows update so i have run a system restore to a previous time when this worked, but no joy. I have also unistalled the old graphics card drivers and installed the new ones from the AMD web site and again nothing.

BSODs And Loss Of Internet Connection Upon Restart?

Jul 2, 2012

My computer is relatively recent only being bought back around Feb/March. For the past month the machine has been crashing and when I log back in I need to restart my router in order to get my internet connection back. The strange thing is that other computers connected to the same router also lose their connection shortly after the BSOD on my machine (both machines have wired connections). I am using the same OEM copy of Win 7 Professional 64 bit that was installed when I bought the machine.I have tried updating the drivers on the network card but that does not seem to help. I also tried looked at the dumps with WinDbg to see if I could find a specific driver that was playing up. I also turned on the driver verification a couple of times to see if I could find a driver that was suspect -- that caused almost immediate crashes but I could not get to the bottom of what was causing it but it could make it happen by starting up Mumble.The BSODs have so far seemed to happen when I am playing a game, using something like Mumble, or watching a stream.

Asus P5KC Intermittent Connection Loss

Oct 7, 2009

I have a problem where my Internet connection will drop at least once a day. I have Windows 7 Business x64. It will first simply stop working, as in it looks like it's connected, it still has a public IP but I can't ping out and no browsers work, nor any games etc (you get the picture). If I try release/renew it'll either hang or give me a 169-address. To fix it I have to reboot my computer and it starts working again.

I have an Asus P5KC motherboard using the Windows 7 Windows Update drivers, and it's been like this pretty much since the start. I've turned off all power saving modes everywhere I could find and any sort of hibernation settings, and still it'll cut off almost always once a day. (I have a VNC server so I can log on from work, so I can tell when it 'crashes'.)

What's funny is that it often doesn't happen when I'm on the computer, it's mainly when I've been gone for a bit. That's not to say it hasn't happened when I've been at it, it's just more uncommon.

It's setup to a switch which in turn is connected to my modem. What's telling me that it isn't neither the modem nor the switch that has the problem is the fact that I have a mediastation which doubles as a webserver also connected to the router and it has never once cut out. I've tried switching the ports on the switch (ha-ha) to no avail.

I've been thinking about installing the Vista x64 drivers from Asus but I'm leery of trying because I don't know how similar the two systems are.

Is this a general issue with this board? I'm getting really sick of this problem. Hope somebody can help.

Also, I'm sorry for not posting this in the megathread we apparently have but I couldn't bear slogging through 43 pages of white noise and hope that my post wasn't lost at the tail end of it. There are so many issues being handled in there that I can't make heads or tails of who has the same problem.

Wireless Signal Loss

Dec 6, 2009

I have new Acer Aspire 5739G laptop and fresh Windows 7 on it.

The wireless card is Intel WiFi Link 5100.

The problem is that wireless works only in short distance with access point - max distance is about 5 meters.

In that distance everything works fine.

But if I go farther or to another room it disconnects.

With other laptops all works fine even on very large distance.

I tried such things (nothing helped):
* uninstall, reinstall or update drivers
* install newest drivers from Acer site
* install newest drivers from Intel site
* tested with xp & vista drivers
* on network connection properties unchecked all things except tcp/ip v4 protocol (microsoft networking,sharing, link layer topology,QoS, TCP/IP v6 ..)
* disabled homegroup
* on adapter properties changed signal frequencies (1,6,11),
* on adapter properties changed standard type to work with: 802.11 b or g
* on adapter properties changed signal to MAX, don't use power saving
* disabled Internet security, firewall
* Changed access point signal broadcasting with no encryption or wpa
* it disconnects from another access point the same way (problem with system not wifi AP)

Maybe something forgot to say, but there was few hours of testing and can't fix it .

Power Loss To Notebook Shows Loss Of Windows Activation?

Jan 15, 2013

I had a power loss while running on battery (it still showed power left, but suddenly shut down anyway) and when I restart, it reports that the Windows is not activated and Window is not genuine and system might be a victim of "counterfeiting."

Is this a virus (I have MSE on continuously and about once a week scan with Malwarebytes)? I have run 'sfc /scannow' with filtered output ('findstr /c: "[SR]" c:.....logsCBSCBS.log" and it appears as usual.

How can I lose my Windows activation?

Wireless And LAN Connection?

Dec 23, 2011

Ok so I just got a new computer and I ordered it with a wireless adapter card. The adapter was backordered so I used an ethernet cable until it arrived. I tested the connection speeds with testinternetspeed.org (legit or not idk. results were pretty consistent.) With just LAN i got 8Mbps download. With just the wireless i got 15Mbps. For the hell of it I tried it with both in. I got 45Mbps. With such a good connection I would love to keep it like that but my question is will this setup potentially harm my new PC?

I have a bunch of stuff on the wireless network, but it seems my laptop is the only one causing a problem. My primary card is a intel n-1030, but I've also tried a wireless usb adapter and have the same issue. I have even tried a different router. Same result. updated drivers, flused the DNS.

I have a Wireless Trendnet TEW-432BRP router. My wireless internet connection keeps dropping every 30 minutes. After it drops it usually reconnects by it self in like 1minute.

No Security In Wireless Connection?

Sep 11, 2012

Just found out that my neighbour can access my ISP via my wireless 802-11g connection. And I can access via his connection...Not a good situation. I have checked security settings in both my router and Windows 7 network connection. I have checked that WPA2-PSK security and AES encryption is selected and a 8 digit network security key is current. I have disabled sharing. When connecting the network does not ask for a network security key but connects instantly and functions correctly I can see but cannot connect to another neighbours connection because it asks for a network security key and I do not have it.

Wireless Connection Kept Disconnecting?

Oct 2, 2012

I just bought a Windows 7 laptop (I still have my old XP laptop). I am now in Las Vegas and trying to connect to LaQuinta's wireless network from my room. My XP laptop has no problem and stay connected all day long. But my Windows 7 laptop has been having problems. The wireless connection kept getting disconnected every few minutes. I have called LaQuinta Tech Department and they couldn't figure out why either and kept telling me it's my laptop.

Wireless Connection Error

Oct 17, 2009

Well, i also have the Windows 7. I can connect with Ethernet without any problems. When i atepmt to connect using the wireless Belkin desktop card. i get this problem found by the Windows Network Diagnostics...(Wireless Network Connection" doesn't have a valid IP configuration) marked as 'not fixed'

So i contacted my ISP and once i told them i was running Windows 7, they no longer wanted to help me. (Frontier)

I have 3 PCs, 2 with Windows 7 and one with Vista.

1**My gaming PC(Windows 7) is connected via Ethernet and connection is fine.

2**My HP laptop (Win Vista) is connected via wireless, and is working fine.

3**My newest PC(Windows 7) was connected with Ethernet, but we cant deal with the wire hanging off the loft, so i got the Belikin wireless card. It installed fine, and sees my home wireless network, the password is correct, as well as the encryption, and security type.

But when trying to connect, i get a "Connecting to the network is tanking longer than usual" followed by a "the connection was unsuccessful"

I run the troubleshooter, and first it tells me to reset my router, which i have dine, and it doesnt help, so i go on to diagnose additional problems, and that is when i get the most important problem.....(Wireless Network Connection" doesn't have a valid IP configuration) marked as 'not fixed

I read a post by Esparko in this forum, with a very similar problem that was solved by SquonkSC..... Can anyone tell me what is wrong, and how i can fix this plz?

The Wireless Connection Problem

Oct 23, 2009

It seems that several people (myself included) are having the Win 7 disabling a wireless router issue. I've searched through this forum and see several threads. If anyone has the solution (other than disabling HomeGroups, I kind of like this feature!) can it just be made a sticky so we don't have to search for it?

Temperamental Wireless Connection

Oct 30, 2009

Just bought a new PC, it came blank, and i have installed windows 7 64x Professional onto it, but am having some problems with the wirless connection.

I have a realtek 8185 802.11b/g wireless card. Other system specs listed in my system specs.

The issues are as follows: Most annoying: - random slow downs in the connection. just during normal use, i won't be able to load webpages, do any downloads, or loading pages will be extremely slow (1-2 minutes per page, usually with errorrs). will often spontanesouly resolve 5-10mins later, only to occurr again another 5-10 minutes later.

No errors reported in the system tray or on using the windows 7 toubleshooter.

- about 1/5 times i boot up, it cannot connect to the network, with error message in the system tray. trying to 'troubleshoot problems' cannot fix it. if i restart, usually connects straight away

- every couple of days, some sort of error occurs, where the system tray pops up with an error message. troubleshooter is then able to resolve the error.

I have updated the driver through windows update. Driver date 10/09/2009.

We have 3 other machines (all running xp - 2 old lapotps and one netbook) none of which experieince any issues. During periods of slow/nonexistant connection on the windows 7 machine, the xp machines haver perfect connection.

I have tried restarting the router many times, and it doesnt seem to do anything.

ALso, dont know if this is related, but my ethernet ports (which i do not use) - Realtek RTL8186/8111 - are reporting errors in the device manager. when i try to update the drivers, thers is an erorr that the update did not fix the issues.

My thoughts would be that perhaps there is a loose connection inside the machine itself, but i think that network adapter connects straight into the motherboard?

Also, i have two different types of RAM installed (2x 1GB, and 2x 2GG sticks), which people have mentioned may cause some issues (I have problems not being able to come out of 'sleep', and i think the RAM causes this - but this issue doesnt bother me).

Lost Wireless Connection To Printer

Jan 21, 2011

My Partner is a professor at a major university and conducts a consulting business from home. We have 2 old desktops and a new HP Pavilion notebook on our home wireless network. The new notebook was set up by a University tech person 12/10 and was functioning properly. All the computers are linked to our older hp Laser Jet 1300 PCL 6 printer. One day the notebook froze and when rebooted it had lost its connection to the printer. I have done everything I know and followed numerous "geek" instructions to reconnect. So far I have succeeded only in losing my own printer access on my old Dell Dimension 2400 desktop. Prior to that, however, both old desktops were printing, even as the new notebook did not. Connection to the Internet is fine and the signal strength from the new Belkin router is "Excellent".
