Pending Intermittent Network Loss
Jan 12, 2011
Running 5 PC's and a laptop on a wired/wireless network at home. One PC running Win XP Pro started dropping the network connection (so it appeared) during browsing. Have found the following:
1. MSN messenger runs fine, and doesn't drop out
2. AVG antivirus updates with no issues
3. Web Pages in Chrome and IE will load fine one minute, then cannot load or pause for 1-2 minutes while loading
4. Can ping web addresses/IP addresses from command prompt with no issue.
5. Have changed the network connection from Ethernet to Wireless, which makes no difference to the issue.
6. If I "repair" the connection, and the network refreshes the IP address, I can browse successfully, for about a minute, before the issue occurs again. "Repair connection" again and can browse again for a minute.
7. Checking connected devices to the Netgear router, shows the PC name sometimes, against the IP address, other times it shows the PC as "unknown" against the PC address (when this occurs, web browsing is lost)
8. All other PC's on the network are fine.

My PC is connected to a network with my company. My PC, only my PC, seems to get random and quick drops in internet connection but the connection to the network/domain remains active.
1 - Open Internet Explorer
2 - Receive "Cannot Display Webpage" message.
3 - Refresh page quickly and the page shows up.
sometimes step 3 takes 3 or 4 times, seems to be getting worse as the problem has been around longer, but most of the time a quick refresh works. Same thing happens with Pandora, my standalone player for Pandora will lose connection but come back with a quick "RECONNECT" button.So, as you can see, it's only dropping out for seconds, 1 - 30 seconds at the most, my thouoght is the Ethernet card??

I am running an 877W in the home that for the most part works fine, however after being connected for a variable amount of time I partially loose my DSL connection. Line sync stays up, but the traffic is lost.
A shut/no sut of the atm or dialer interfaces does not resolve the issue, only a reload or power down/up will fix the prob short term till it happens again.
Am currently running advipservicesk9-mz.151-3.T1, but have also rolled back to advipservicesk9-mz.124-24.T5 which has the same issue. Have tried a 857W with the same results. So ruling out IOS and hardware, its pointing to a config issue. It has also only been an issue since changing from ADSL1 to ADSL2+.
interface ATM0
no ip address
no shutdown
no atm ilmi-keepalive
exit
[code]....
I've tries some changes mentioned here and from other sites, but no success yet...

I've been having a problem for a while now wherein my internet connection seems to randomly drop for anywhere from ten seconds to a minute, then come back online. It's been doing this over the lifespan of one router, and continued into the life of this new one I have, which is a WNDR3700v3 Netgear.
I called my ISP and they fiddled around with things on my computer, but the issue is still going on. Rather than slog through another three hours with them, does anyone here have any tips for what I might look into for the cause?

I am having wireless connection/internet issues that are irritating me to the core!!! I have called tech support 4 times now, and I still can't get everything to play nice...I have the 655 set up as a wireless router to a Windows 7 laptop, one iPad, two iTouches, and one N3DS. I can't find a setting that will work with all devices. Here are the senarios...
1) Settings: Wireless enabled, 802.11n only, Auto Scan off-channel set to 1, Best Transmission rate, Channel Width Auto 20/40, Visible, Auto WPA Mode with AES Cipher and a pre-share key. This yields fantastic results with my laptop, it can stream video for entire episodes, and I have no problems with loading webpages in either IE or Firefox. However, it does not support the kids iTouches or N3DS.
2) Changed the above to mixed 802.11n/g AND ALSO tried 802.11 only: iTouches work and can connect to the internet, but laptop doesn't like it. I get "Problem loading webpage" every other time I access and website, and streaming stop every 5-6 minutes. Bars indicate wireless signal is strong, but intermittently get that yellow triangle.

Every "once in a while" (about a week with my network load), the SG300 crawls to an almost standstill of all IPv4 activity (haven't got IPv6 enabled here yet, so I can't comment wether this applies to IPv6 as well). It seems pure L2 transmissions is not affected, but L3 definitely is (down to 20mbit as opposed to the 600+ rate I usually get).
Soft-rebooting the switch (via the webgui) useful, and the intervals of the crashes seem related to total bytes transmitted, not time. I have jumbo frames enabled, and disabled flow control on on the switch and all hosts.
Firmware Version is 1.0.0.27, md5 1987292110f5657e74308dde30c03dc4 Boot Version is 1.0.0.4 md5 4c9a0b6a9f1346736646d08ab94ae2ac

We run windows server foundation 2008 and have about 15 workstations. I had been running the network on 10 workstations prior to moving the server to our new location about a month ago. All was working well. We had run with the 15 workstations no problem in our new facility for several weeks. many of the computers are dropping the network connection now intermittently, with no predictable pattern. I can't seem to reproduce the conditions that cause the drops.

I have a Compaq with XP wired on a Network with a Belkin N600 Router.There are 5 computers on the Network, (4 wired, one wireless) and this is the only computer that I have problems with connectivity. It connects to the Belkin through 2 switches.Typically when I turn the system on it connects, downloads mail, etc. After a short period of time there is no connectivity to the network for printing nor the internet.I may get connectivity randomly again after a while, but you never know if or when you will get connectivity again for sure. I am using Explorer.I had loaded some Belkin software with no luck so I uninstalled it. The other computers have no special software for the router.

I have cable modem coming into the basement hooking up to Linksys Cable Modem (1 yr old). The cat6 line leaves the cable modem and goes approximately 60' through the wall to an Asus-NT66U wireless router on the main floor into the WAN port.I then have a cat6 line go back through that same 60' of wall coming off the LanPort1 of the Asus-NT66U router into a Cisco/Linksys SE2800 8 port gigabit switch (a year old as well).
The problem I am having is as follows. I have been getting intermittent "Unidentified Local Network" problems off an on which I have tried many of the fixes for, evidently unsuccessfully ranging from duplex speed, network ID etc. I had updated the firmware on the NT66U to the latest and am still having problems.
I never have problems with the wireless network which always has connectivity to the internet, however the local is the regular problem. So, to further compound things I have 3 Smart TV's hooked up to the Cisco SE2800 switch over cat6 as well. Those were all working recently until this most recent hiccup and now none of them are working regularly. They can sometimes "see" the wired network and my media server software, but it is intermittent, slow, and never works and often can't see at all.
The TV's are all set to static IP's over the wired network (192.168.1.114/.115/.116) they are the only static IP's out there.The cables are all good and have been repeatedly tested in a variety of ways. All the drivers and firmware are up to date.I think I have a problem with the router/switch communicating and passing through data,The switch does not need a crossover cable, does not seem to have a management menu, and not sure what else to do.

I have a Cisco 1242 AG wireless access point with the goal of having multiple SSIDs. I set up one network which broadcasts correctly but only sometimes can I connect to it.
And, even if I connect to the network, I cannot get a DHCP address for the client.Other devices connected (but not through this Access Point) to the associated VLAN 60 can get a DHCP address and connect just fine.Here is the configuration for the Cisco 1242 AG access point in question: [code]
Lastly, here is the information on VLAN 60 from the distribution switch. As mentioned, other devices connect to this VLAN and get IP addresses just fine.

I just built a new computer running Windows 7 with an Intel 82579V Gigabit on the motherboard. Since last night while playing an online game, I have occasionally noticed sudden network failures where I either time out of my game or severely lag for 10 seconds before the game catches up.
My other network hardware and setup remains unchanged during this build.I have never had issues with my internet connectivity from my ISP.
The problem is not consistent and I'm not sure how to repeat it. I was playing my online game for several hours and then suddenly started having problems every 5 minutes with disconnecting.I can watch the network utilization in the Windows Task manager drop suddenly and then spike back when I reconnect to the game. Similar visual seen on the Tomato software on my router.
So far I've grabbed the latest drivers for the network chip from my motherboard manufacturer's website and turned off Teredo. I also made sure no power saving features were enabled on the network chip in the device manager.

I'm trying to get my wife's new 'All Fine 7" netbook Windows' connected via wireless connection. I had a muted attempt at it but so did my daughter and her boyfriend. I've got as far as it saying 'connected' but as soon as it does I get a message; Error from RasDial. I think I have created some conflicts perhaps! In the control panel I have done the following:'Internet options' under 'Connection' I've highlighted 'USB 'Network & Dial-up connections I have a choice of 'My connection' 'Main Computer' 'RT28701' & 'ENC28J601' The connection I have so far seems to be using the RT28701.My other option to 'USB is to select 'Desktop @ 19200' but that didn't seem to work either.

I have fresh installed the LMS 3.2.1 without any errors. Then I am adding device in CS, give it correct credentials. Its appears in RME automatically, but it always remain in Pending devices in RME.
I have run a job in RME to check the devices credentials and it's appearing that credentials for snmp are wrong but ssh/ telnet appears as "did not try". Although I have added the correct credentials in CS for device, but it appearing as wrong in RME.
Also when I add device in CS, it's not automatically picking it's device type, until in CS I define its device type manually.

We are facing issue related to STP.I am getting MAC FLAP error on Cisco 4510 switch. The effect on network is intermittent Pkt drops in the network. When I checked the specific Ip address I am getting the same with two different. [code] Vlan is created on CORE switch and assign priority 0 than CORE switch should be the Root. but instead Root port is becoming the port where server is connected. Server at last connected to CORE switch via HP switch via other Vlan to CORE switch and creating a loop as shown in Diag. [code] The Priority of Vlan 102 is changed and Root port has been changed due to that. The Bridge ID is the same as CORE switch.

im intending to setup a small office network through a sever at my work and would like to know if it is possible to have the network running with each pc having its own internet connection.in theory this should work by having the internet connected via usb which will leave my ethernet ports free for the network..i would just like to know if this route will work just like that or will i need to have a rethink.

Brand new MSI system using windows 7. we're using a wirless network in the house, and up until today it's been fine. Randomly, Windows is no longer detecting any networks.
I've confirmed there is no prob with the router or signal as I can detect the network in my room and connect to the internet (using a homeplug hardline). I've tried enabling and disabling both the router and wireless card, a system restore (windows made no changes), and when I came to use the windows 7 troubleshooter - it says the device is not enabled?

Okay, so our old computer took a dump & our friend rebuilt us a new one and he threw in a new router to go with it. Its a D-Link router, which is directly connected to our desktop. However, upon completion of a new desk installment, we put the router into the cabinet and my gateway laptop immediately stopped being able to connect to the internet or the router at all.
1) The router is connected to the internet and broadcasting.
2) I've reset and refreshed the router and my window of available networks on my laptop, which did not work.
3) I've pulled it out of the cabinet, which also had no affect.
4) I did a manual search for the router, and it says the network already exists and asks if i would like to connect and upon agreeing to this, it returns me to the page of available networks, which does not include my router.

i have recently added to a domain. The initial setup is a server running windows 2003 and several xp machines which logon to the domain using mandatory profiles. However, after adding windows 7 machines and logging them on to the system it doesnt load the profiles. (which is fine as I understand you cannot use the same profiles with windows 7+xp)The problem is it automatically creates a roaming profile when logging off and saves it back to the same path as the other profiles under user.V2 which is growing considerably and causing huge logoff and logon times.How can I get the windows 7 machines to not attempt roaming profiles back to the server and instead to just save the profiles locally when logging off.

I'm having what appears to be a random issue with my systems' ability to display various PC's on my network. Sometimes all the computers display when I open my MSHOME network and sometimes only six of them displayand the rest don't. I can always ping the computers whether they display or not.
My network has 13 computers, all running Windows XP SP3, one modem, one router and several switches. Some of the computers are access via wireless but most are hardwired to the network,
To the best of my knowledge, this is a recent event. The network has been up and running for over two years without me ever seeing this problem. I don't know if the problem exists on all computers but I do know that it exists on my personal workstation. It almost seems like an IP addressing conflict but there is no system error message indicating same.

I keep losing connections to the internet and getting a couple of different messages that the Gateway IP address is invalid. There are times it happens every few minutes and other times I can go for a couple of days without it. Also, we have to have satellite internet which has such an inconsistent speed. Is it the internet speed inconsistency or the 4 year old Belkin N Router?OK, so I tried to copy the information from the CMD window, but I can't get it to work. After I got the information and right clicked and clicked "select all" then what. I couldn't copy it. I can't find my way back to the instructions.

I am connecting to a Wireless network, through a ZyXel ZyAIR G-4100v2 router. My problem is that I am experiencing very regular packet loss every minute or so. This lasts for around 5-10 seconds on average. I am running XP with the latest service pack. So far, I have checked out;Wireless Zero Config scanning of new stations (disabled that feature).Xirrus network scan (signal is fine and consistent). I am not suffering from any degredation in signal, the problem seems to be that the router is simply not allowing anything through at regular intervals.

I have recently been testing out the Kaillera netplay application thats embedded into a few old console emulators. Now the major problem is the de-sync between clients and I was wondering which is the best to reduce this.Say I have an upload speed of 1.2 Mbps and a download speed of 11.28 Mbps. Obviously, I am capped by my upload speed when it comes to changing how many packets i can send/receive per second because its all one setting and I am usually playing P2P.So, I am not entirely sure how big the packets are that are being sent, I am guesstimating based on what they said on Kaillera website that it is around 200-300 bits.Anyway, with my current upload speed I can transfer at a rate of like 600-800 packets per second depending on packet length.De-sync's happen quite often especially in the higher rom size games like Mario Party because of all the data being transferred. Would it be wiser to increase my setting of pps from 20 packets/sec to 60 packets/sec?

My wrt110 firmware .05 has been working fine until now. I have a couple of phones, 2 printers, 3 laptops and a wii happily connecting to it. However now when I power on the wireless device, nothing can connect wirelessly. Wired connection is fine, but my wireless network disappears. No device can find the network, although it is there and set up on the admin pages. I pull the power chord out for 30 seconds and try again to get it going again, a bit like trying to start a car. Everntually devices find the network.
On two occasions it has forgotten the wireless settings and restored an open 'linksys' network. It's really infuriating becuase whilst I restore the SSID and use the same key, not all the devices actually recognise it and have to be reconfigured on the devices.

So I have an WRVS4400N V2 and just got a new laptop with an Intel 6230 Wifi card in it and have an odd problem.While the laptop is on battery power the network gets massive packet loss.
I don't know what to do.Laptop manufacture says its AP but AP worked fine with old laptop and works fine when laptop is on power and all other devices seem to be fine with the exception of my Xbox 360 that wont connect if I have it on WPA2 but I will post another thread for that.
