WGR614v9 / Windows 7 Desktop Loses Network Connectivity Twice A Day
May 24, 2011
My primary home machine loses network connectivity for a very brief moment once or twice a day. Here's what I've observed over the past few months:
Seems to happen every 12 hours after a restart Disconnect is very, very brief. Putty sessions, online games, or other applications that require a consistent connection disconnect but it's rare that I can see a ping fail when everything else disconnects.Does not coincide with network problems on other machines (Xbox/media PC/wife's PC).
Other details about my system and home network:
Windows 7
Asus motherboard (couple generations old) with onboard ethernet
Ethernet > wired hub > wireless router > cable modem (wife's PC is connected to the same hub and does not have the problem, at least not on the same schedule)
Things I've tried (and will probably now try again just in case)
Restore network card driver (I'm in the process of finding a specific one for my motherboard)
Tinkered with power saving settings in the ethernet card drivers.
Fully up-to-date Windows install.
Static IP address reserved by the wireless router running DHCP
I'm not 100% sure, but I think this problem persisted across Windows OS upgrades (from Vista to Windows 7 a few months back)
By far the weirdest part is that it seems to happen every 12 hours. Like clockwork, I can predict that I'm going to disconnect from any persistent online connection if I know the last time I restarted my machine.
Solved:I caused my own problem long ago when trying to set static IP addresses in my home. I have a Netgear Router (WGR614v9) and I played with the Address Reservation feature. In addition, I manually set the IP address I wanted to have on my machine using the normal network card properties. Setting the IP address manually is what seems to have caused the conflict.
Finally looked in the Windows Event Viewer and the culprit was quickly identified. At time of restart and every 12 hours later, the following error appeared:
The IP address lease 192.168.1.20 for the Network Card with network address XXXXXXXXXX has been denied by the DHCP server 192.168.1.1 (The DHCP Server sent a DHCPNACK message).
I accidentally fixed it for all affected machines by changing the start address of the DHCP server on the router (increased it from 20 to 30). That seemed to kick all the manual entries out and set them back to automatic obtain mode.

This is my network topology. Sometimes it just suddenly loses conenctivity or traffic for unknown reasons, like the internet hangs for much time or maybe some routers just stop responding, even restarting ! Do you think there should be a Multi-WAN router that could take 4 WAN lines and give one LAN to plug at a switch for a better performance ?I know that my setup is wrong, give me your opinion about it and how to fix it .

I have one HP Desktop that decided one day it doesnt want to connect to the internet.
On the network we have two HP desktops (wired), one Dell desktop (wired) and 2 dell laptops (wireless) all connected to a wireless D-Link DIR 655 router . All computers are running Windows XP. All are able to connect to the internet except one HP desktop (only recently).
I have tried connecting the HP desktop in question to the wireless router via a different cable and still no connectivity. I tried disabling and renabling the internet/repairing it to no avail. I've restarted the wireless router and modem. Nothing. I've even tried restarting the computer (who knows it's solved problems before).

I have a Samsung SCX-4623FW All-in-One Printer that will not maintain a connection to my wireless router a Linksys WRT160N. Samsung technicians have not been able to assist after multiple calls. They sent me to a printer repair store which reported they had no problem with the printer working on their wireless network. When I used the setup disk initially it would connect the printer to the network and I could print from my laptop wirelessly, but the connection never continued working more than a few hoursThe router has no problems in connecting to 3 different computers.

My internet connection goes up and down. After further investigation, I've noticed that as soon as i receive a certain # of packets, the internet connection goes down. It may be a process or application that is taking away these packets.

Having just received a new Dell XPS8500 running on Windows 7 and I have the following problem: My wifi connection is turning off and the name of my network is no longer displaying in the list of available networks. This means that I am unable to access the internet or emails rendering the computer unusable as I am not on broadband (using access from another router close by). It is absolutely critical that the wifi connection is always on.

I have a client who has 4 computers in the house all running wireless. 2 desktops and 2 laptops. One of the laptops is running XP and after 5-10 minutes of surfing, the internet stops working while all the other computers retain a good internet connection. Repairing the connection via the taskbar icon fixes it temporarily until the issue reoccurs.

Major symptom: Maddeningly intermittent wireless issues with Asus laptop after repair. Unable to connect to network after sleep or reboot on upper floors of house.
History:
1) Laptop wireless was working fine but power jack and case were damaged.
2) Sent away to Asus for free repair (pulled the HD first).
3) Got it back and seemed fine, but...
Problem:Wireless starting dropping after sleep. It's my wife's laptop and she usually uses it on the 2nd floor of the house.Routers are on the first floor. It failed the same way on both my G and N routers. Played with all sorts of settings, disabled IPv6, reinstalled drivers, checked for BIOS update. No luck . Eventually saw some event log entries that might have been associated with a bad wifi card. Ordered a new Intel 100 N (OEM model) and replaced card, same issues. Swapped card with a Broadcom 1510 from an old Dell I had. Same problem.
Tried more settings, static IP, flushing DNS, etc. Same problem.At this point the event log has nothing notable in it, no error logs anywhere the wireless card will just report no connectivity.when I work on this laptop I take it down into my office, which is on the 1st floor by my router. The laptop works flawlessly there (10 feet from the router). So my theory at this point is that Asus damaged or otherwise messed up the laptop antenna while repairing the laptop. most of the time on the 2nd floor the windows wifi icon reports a perfectly good signal, and if I boot the laptop on the first floor and walk upstairs, the laptop works fine(as long as I don't reboot or let it go to sleep).

ATTACHED: My current running config with sensitive info taken out.
I have a Cisco 881 Router connected to cable modem. The router is running IOS 15.1.
I have it configured exactly the same way as an 877 router running IOS 12.1 which does not exhibit the problem. Just a standard LAN/WAN config with basic routing/firewall.
When the internet connection is lost for any reason and then re-established the router will no longer pass internet traffic unless I reboot the router.
I used Cisco Configuration Professional to configure the router. The key setting seems to be the Router Static Route. We have a static IP and I set static route with the "make this the default route" checked. Then I set forward (next hop) to the IP my ISP gave me as their gateway.
This is exactly the same way I set the 877 router using the same ISP but in a different office.
Every so often the internet is lost due to power outage or the ISP doing something on their end and every time that happens we have to reboot the router which is quite annoying.
I did not have the "permanent route" check mark checked but I do not have it checked on the router that does not have the problem either so I don't think that's it.
When I set the static route to "interface" then added the static IP of the next hop it will continue to work for incoming connections but not outgoing.

I'm using this router for connecting 2 PCs, one lap top and few mobiles.The LAN network is always stable and never loses connection, but I'm having problems with the wireless connection. My lap top runs on wireless, and 3 Android mobiles, an xperia mini pro (problematic), xperia Tipo and Alcatel OT-908F. Almost always when I login to facebook on any of the mobiles, pictures won't show, and also youtube videos thumbnails won't show. On the xperia mini pro after 2-3 minutes of surfing, or doing anything else the connection drops, and then the mobiles can't see the wireless connection. My lap top can see it, but it cannot connect. After restarting the router everything is back to normal.

In my LAN, I have always been used an Aironet 1250 for internal use and always work fine. Now, I added a 3com AP but both AP are not correct. When I turned off the AIRONET 1250, the 3COM AP settings works fine. When both are turn on, the 3COM AP loses connectivity all the time.I have heard about the overlapping channels in 802.11b/g networks.

Internet connectivity on my laptop is lost shortly after beginning to upload/download files over the internet to my cloud storage provider. I also lose connectivity when transferring files to or from the laptop within my LAN to a desktop computer connected via wireless router as part of a workgroup. Connectivity is only restored once I restart the laptop or uninstall, then reinstall drivers for my wireless network card. The issue then reoccurs once file transfers begin again.The laptop is running Windows 7 Home Premium SP1. The driver for my Intel Wireless WiFi Link 4965AGN internal network adapter are up to date. I have a Linksys WRT610N ver.2 router, and an HP Pavilion dv6500 laptop.

I'm currently implementing Microsoft System Center 2012 Operations Manager, the curent stage of the project is to add the network devices to SCOM via SNMP in order to monitor them, I am able to add them all and monitor; however, my ASA 5510, although SCOM discovers the ASA via SNMP and adds it to the network monitoring list, it loses SNMP connectivy every 30 minutes, and 15 later it reconnect with SCOM, then after another 15 minutes it loses the connection again, and so on and so for.

I have a new EA3500 router that's working great for a variety of devices* except a Windows7 laptop. 24 hours after establishing a connection, the laptop loses connectivity and it's very difficult to re-establish a connection. Usually I have to reboot the router, but 24 hours later the problem returns and Windows is unable to connect.
My router settings include DHCP client lease time set to 1440 minutes (24 hours), so I thought the problem might have something to do with DHCP lease renewal. To test this theory, on Saturday night I did ipconfig/release and ipconfig/renew and established connectivity from the laptop.
Sunday morning I spoke with Linksys support and changed several settings per their recommendation:Network mode mixed (I had it on N-only for some reason)Assigned different SSIDs to the 2.4GHz band and 5 GHz band2.4 GHz band channel is 20MHz only, using channel 95 GHz band channel is 40 MHz only, using channel 161I also power cycled the router. Everything worked fine until Sunday night, 24 hours after the release/renew, when I lost connectivity. I am not sure what to try next and whether the problem lies with the router or the laptop.

i currently have a netgear wgr614v9 running the most recent firmware update and a tplink nr741nd running the latest dd wrt firmware.the netgear is my main router connected to the modem positioned in the living room attached to this is a wired ps3, wii and various laptops connect wirelessly to this. In my bedroom i have the tplink router is is setup as a client on the netgear router allowing media network drive access to the internet.
eg.
--- wired
~~~ wireless
modem-----netgear~~~~~~tplink----network drive
What i would like to achive is to be able to connect to the netgear router wirelessly and have access to the network drive attached to tplink router.I have tried a client bridge on the dd wrt firmware but this does not work at all. I have read that i need to setup a VPN on the dd wrt but i can find anything on how to do this when trying to access a drive on a second level.

I have 64bit Windows7 Professional OS, and have installed Windows XP Mode, I have a wireless and ethernet-capable Router. My HP PC has both wireless and ethernet connection capability.When running Windows 7 alone, the Internet access is connected by wireless to the Router, and runs well but when I start Windows XP Mode, the Intel 21140-based PCI Fast Ethernet, complains if the Ethernet Cable is not plugged in to the Router.When I plug it in, I still get no Internet connectivity, the error is Windows cannot obtain an IP Address. How can I have the wireless and ethernet connectivity co-exist together or separately when required.

It is running on windows vista home premium 32 bit sp1, if that matters.I have just had my computer's motherboard changed recently. After reinstalling the wireless adapter, the internet works! Until I found when I came back later that my internet shows unidentified network with limited connectivity. It happened when I was not around and my computer went into hibernate mode after downloading firefox installer. There is no antivirus installed, so it can't be a problem. My wireless adapter is the usb type,brand tplink: TL-WN721N. Tried a few methods suggested by the internet but nothing works: unchecking the iv6 box, follow the steps that starts with the regedit part, uninstall and reinstall the driver for the wireless adapter, fix the ip address.There is no problem with the network as the rest of the computers and laptops in the house has no network issues. But all of them are running on windows 7.

I connect to the internet using a wireless USB. I woke up this morning and the internet showed that it was connected yet it wouldn't allow me to open the web or anything such as "msngr" I took the wireless card out for a couple minutes and then tried. That didnt do anything but say acquiring network address. I am not that knowledgeable when it comes to computers but these are the things that I have tried so far :
I went into properties and configure USB . . Made sure that the SSID said "Any" I Also tried going into properties and tcp/IP internet protocol and made sure it was on obtain IP address automatically . Hmm I tried. RUN>SERVICES> to make sure that the DHCP and TCP were started and on Automatic. I then tried system restore :- (went back about 2 weeks) . . Nothing. I then tried RUN>CMD>IPCONFIG/RELEASE *ENTER* IPCONFIG/RENEW *ENTER*.
when I did that it showed wireless network is now connected, yet back to ground zero. It wont let me browse. Its not really connected. When I look at the connection status, signal strenghth is good. Packets sent & received are good. I feel like there is just something little that. I am not getting, that is making this happen.

My desktops _usually_ connect, and then the connection will drop/go slow(14400 slow)/give that little yelow triangle on top of the wifi icon.First i had an edimax wifi PCI, now i have a trendnet wifi PCI. They both do the same thing.If i connect my HTC hero and start internet sharing, it works very well, and is stable. My ethernet works fine as well. It is like my computer is immune to PCI cards?I have tried with different wifi APs now, but its still the same.I have a zyxel adsl modem, and a linksys wifi AP hooked up to that. I noticed, that when my desktop is connected, the zyxel will get some kind of overflow from the linksys. It says "client reached max number of sessions per host" It's like my desktop is killing the network. I have tried many things. Drivers, fail safe, registry cleaner(I know), killing all unnescessary program, switching the PCI ports, but none of it seems to work.
I had my laptop running connectify (access point app) and it actually worked fine, but today it won't connect to that either.I'm going to create another partition on my harddrive, and install fresh windows 7 on that, and see if it does the same. But even if it doesn't I _want_ to find out what is causing this instabillity.When i try running the network diagnostics, it says DNS error, or that the router is fail. But my laptop works fine.Also, when doing speed tests, my laptop gets normal speeds, and my desktop is VERY slow DL, but normal UL ?In speed tests my desktop is very slow, but stable, but during the test, my laptop will first go like 2 mb/s - 3mb/s DL and suddently BURST up to like 64 mb/s although i only have 10 mbit line? It's like its buffering or something. Very weird behaviour, but working fine.And no, i do not have torrent programs or whatever running.Some says that i shout try and change wifi channel and bands, and avoid "mixed" mode, but none of it works. Always the same problem.ATM. my computer can't connect to any wifi at all. It keeps having the yellow triangle.

A few days ago my desktop (which is hardlined into a router) lost all connectivity. My wireless connections work fine and i have began basic troubleshooting; changing ethernet cables, taking router out of the mix, etc. Beginning to think the ethernet port on pc is going out (NIC card?). Funny thing is, it will come back intermitantly for 10 minute increments. power cycling does nothing.

It works then it stops seeing the homegroup machines. After struggling with this I have determined some things.
When it stops seeing any homegroup machines, xp, vista 64 and two dlink 323 nas boxes, I can get it working again by restoring the drive with a backup for a time when it did work.
I ran a lan software that showed me mac address, ip address, master brower and workgroup of every machine on the network. I ran the software when the Windows 7 home premium machine didn't see the workgroup. The software showed the windows home premium 64bit machine was not reporting the homegroup name. Looks to me like something is changing causing the win 7 home not to report the workgroup name. I tried changing the workgroup name, rebooting, changing it back then rebooting and it didnt' fix it.
When the machine is not seeing the workgroup I can ping the other machines but I can't map them using their IP addresses. When it lost the workgroup lately I noticed the first sign this time was I could see the machines and directories but could not access them being told I didn't have permissions/access basically. Can't remember the exact wording.
I am at a loss of what to do to fix this and I would perfer a fix verses reinstalling everything from scratch which may or may not perminately fix the problem.

I have a Toshiba Satellite that I got almost a year ago. I lose connection a lot. I have to often enable the adapter because it has been disabled or when troubleshooting it resets the adapter. We have several other computers on our network that work fine. This is the only one with Windows 7. The router is Realtek RTL8187B Wireless 802.11b/g 54Mbps USB 2.0.

I know there are a lot of threads out there regarding connection issues, both with wireless & LAN connections, after updating firmware to 1.35. To provide a snapshot of my setup...I have 3 GB switches throughout my home, a couple Ethernet enabled Blu-Ray players, 2 XBOX 360's, multiple satellite receivers with Ethernet, 5 PC's, 3 iphones, etc...you get the picture. I also have 5 older DLink wi-fi cameras. So, with this said my setup has been flawless for some time. However, a week or so ago I upgraded my firmware on my DIR-655 to the latest version...everything still seemed fine at the time. Yesterday I noticed we had no wireless internet so I went and checked. Sure enough...no connectivity on my desktop that's directly linked to the router, etc.
I tried rebooting & then resetting the router...got connectivity, but as soon as I plugged my PC into the switch...no IP address. I played around with settings, wiring configurations, etc...I'm pretty up to speed on this setup so I felt I exhausted every option. I thought my router went bad...gave me an excuse to go get the latest so I brought home a NetGear N750...hooked it up. As soon as I changed the LAN IP address range to condense the #of IP addresses I'm giving out again, the LAN connection to the PC was lost...I could not get it restored. I finally got it working, bypassing the GB switch, but the wireless would lose connection literally after a few seconds.
I ended up taking the NetGear router back and bought the exact same DIR-655, but this time it was HW version B1 instead of A and it was firmware #2.00 or something like that. I hooked it up when I got home...configured the system to exactly the way I had it before and PRESTO!!! My system is working like it was before. I can only think that the firmware upgrade I made on the previous router screwed something up in my system.

I have a Linksys E2000 router that is connected to my cable modem. I have a desktop computer that is connected to the router via an ethernet cable, and two laptops in the house that connect wirelessly to the router to get internet access.
This morning, all devices were connected to the internet just fine. I stepped away for a few hours and during that time the desktop 'lost' its internet connection. I have tried re-booting the router and removing-reconnecting the ethernet cable but nothing is restoring the connection.
The fact that my wireless devices are connecting means my internet service is fine, right? So what is preventing the desktop from gaining a connection?

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.

I've recently had to switch to a wireless network, buying a brand new Netgear DGN220v3 (which works great, by the way) and an Asus PCE-n15 network adapter for my desktop pc. Now, the signal could be slightly better, but it's pretty fine and quite fast when available. The problem is sometimes the adapter just seems to "forget" all the active connections and doesn't see any connection at all for a couple of minutes. It's updated with realtek drivers, I've tried using the Asus utility as well (which installs realtek drivers anyway + a -not so useful- program)
