We are having an issue on our domain where both internet and network connection drops at random, this lasts from about 30 secs up to a minute.The Domain server is running Server 2003 and we have afew XP and a few windows 7 machines.All of this is behind a SonicWall TZ-200 firewall.[code]
View 2 RepliesI have a mix of devices that all access the internet via a Deutches Telkom Speedport W 723v my windows devices, HTC phone and even the iPad 2 never have a problem, but my Macbook Pro (Unibody Late 2008 model) and my iMac (Probably 2007 / 2008) keep having a problem with the network dropping out. To fix it I have to switch off Airport and switch it back on again and it re-connects straight away.The Mac OSX software albeit now rather dated on both devices (The Macbook is 10.5.8) is kept up to date using Software Update.The problem amy also now be affecting my APPLE TV2 it never had a problem before but now I cannot connect to iTunes on my Macbook using Home Sharing it just does not want to connect!!!I did try before going into the Speedport and changing channels from AUTO to channel 1 but that did not resolve it. I am going to do it again and try a different channel but logging onto the Speedport is an absolute pain, I can only login using my Macbook Pro when it is booted into Windows XP and on Ethernet as we had all sorts of problems setting it up and could only do it using IE not SAFARI and now the Speedport login only recognises 1 x PC for logging in, if you try a different device it throws a wobbly and locks up!

At 1st I could just click on the yellow triangle and troubleshoot and it would reset the network adapter. I cannot do that now - Im having to disable the adapter and the enable it and Im back on the internet.I have set it up so I am connecting via a manual IP address as I wondered if when the kids PS3 was connecting it was pinching my Ip address.

Had an E4200 for a couple of months now and have not been able to resolve an issue with the router dropping an Apple iPad 2 at random times.The E4200 is replacing a Cisco Aironet 1200, which never dropped any clients, iPad 2 or others, and never displayed any of the issues below.
TECH DETAILS:The E4200 is being used purely as an access point. All extras are not in use and are disabled.
Firmware 1.0.03
Hardware version 1.
BASIC ISSUE:The E4200 drops an Apple iPad 2 off the 2.4 Ghz Mixed (B, G, N) network. The user must then select the network to rejoin. Rejoining occurs without incident. The same issue occurs when the network is restricted to B, G. The drops occur at what appears to be random intervals - sometimes 10 minutes apart, sometimes hours apart. We can have as many as 6 drops in an hour. A ping to the apple ipad shows the device stops responding to pings about 10 seconds before the user is prompted to rejoin a network. Meanwhile, a ping to the E4200 itself from a laptop connected via the E4200 on the same radio as the ipad continues to work without fail during this incident.
1. The iPad 2's cannot connect to the 5Ghz radio. I believe iPad 2's are supposed to support 5Ghz.
2. Both our Apple TVs do not connect to the 5Ghz radio: they fail with a "There was an error connecting to the network. Check your settings and try again. (-3914)" error. Apple TV supports 5Ghz.
3. The admin interface for the E4200 is very slow sometimes. Probably over 20 seconds to render some pages when it gets really bad. As a comparison, Internet-based pages on fast sites that delivered via the E4200 itself load in less than 2 seconds.
4. The HTTPS version of the admin interface can only be connected to via Safari browers. Both Internet Explorer 9 and Chrome 16 fail to connect with a "Connection reset" error. In Chome, it says "Error 101 (net::ERR_CONNECTION_RESET): The connection was reset." This is across multiple devices. There is no issue with straight HTTP.
All other devices - including Macs and PCs - connect fine with the E4200 on both 5Ghz and 2.4 Ghz radios, even if they cannot access its admin interface via HTTPS.I've presented quite a few issues above, but the main one is the drop outs for the iPad 2 devices. I'd present logs on drops, but the thing doesn't record any useful logs.
Basic wireless config:
5Ghz:
Network Mode: Wireless-N Only
Channel width: Auto (20 or 40 Mhz)
Channel: Auto (DFS)
SSID Broadcast: Enabled

I have two wifi routers which I have connected together with an ethernet cable to extend coverage across my house. The ethernet cable is connected to a LAN port on the first router and the internet port of the second router. This works fine and creates a second network that I can connect to the net on. The problem iseemingly randomly, about every 15 minutes, the second router will lose internet connection. My laptops and phone still stay connected to it, but windows lists it as having no internet connection. If I then wait a couple of minutes and reconnect, internet will be working again.
View 4 Replies View RelatedI have a work computer...Dell Latitude 6400, AT&T Global Network Client (Company VPN service), using Novatel USB551L from Verizon, with their new 4G LTE. First connect to Verizon, then it automatically launchs ATT Global Network Client, once connected, the system automatically maps drives. I stay on for about 15 minutes average to 40 minutes that's when the Verizon drops/disconnects. This consistantly happens throughout the day!
1. If I connect to a "local" wireless signal NO dropping.
2. If I tether my Sprint Android, NO dropping.
Only dropping with the Verizon. I MUST have the Verizon dedicated to this work computer to run the VPN and hopefully (very soon) a mandated VOIP with Avaya!Called Verizon- they sent me a new USB thinking that might fix it. But same thing. They are showing signal strength 4G. Nothing on their side.
I have a home network with a Linksys E4200 connected to the ISP's fiber box. The problem is that when I'm connected to the Linksys, either wired or wireless, the connection to the internet will drop after what seems to be a random amount of time (normally anywhere from 2-10 minutes). I can restore the connection by doing any of these things:-reboot Linksys-disconnect and reconnect cable from router to fiber box-if on wireless connection, make changes to the router wifi settings, like change the wifi channel.The internal network stays up, and I can ping both the internal and external ip of the router, but not the fiber box. I have also had the same behavior with an Edimax Wifi AP and less frequently with a Edimax router (once every 1-2 days). I have done everything I can think of:-changed the wifi channels-changed the ip ranges, subnets, turned router DHCP off and back on-booted the fiber box-changed cables-updated all routers to the latest firmware, the network cards with latest drivers...and loads other things that I don't remember right now. For the wifi side of things, there are no other networks in range that could interfere. The same problem occurs on both my and wife's Win 7 laptops and on the iMac (latest OSX). Here's a fun detail: while the Linksys has lost its connection to the internet, I can still access the internet through the old Edimax router connected to the same fiber box, either wired or wireless.
View 1 Replies View RelatedI've been having some issues with my network connectivity for a while now, and I haven't been able to figure out what the problem is. I run a wired connection to an Ethernet port in the wall of my university dorm. I have verified that it is not a global network issue or an ISP issue; this problem only happens on my PC.My network connection drops/disconnects randomly throughout the day. When I say disconnect/drop, I mean that all attempts to ping or access the internet fail. A few minutes pass before the Network and Sharing center task tray icon shows a warning sign saying that my computer could not connect to the internet.This is temporarily fixed by doing an ipconfig /release and ipconfig /renew, but I have to execute these two commands about 2-3 times a day on average.
There is no exact interval between the disconnects, nor does it happen when I am running particular programs. The disconnect happens regardless of what I am doing at the moment (gaming, browsing the internet, leaving the computer idle).A month back, I installed some Windows Updates and suddenly my internet connection was almost completely broken. I was experiencing the same issue, but much more frequently. My internet would die within 10 seconds of executing any download, but Windows wouldn't recognize that something was wrong. At first I thought the ZoneAlarm, Avast!, or the SafeConnect (as required by my university) services were causing trouble but uninstalling/disabling these services did not fix the problem.I also tried reverting to my default ethernet drivers, which did nothing. I uninstalled and reinstalled multiple versions of my drivers to no avail.However, the internet worked just fine in Safe Mode with Networking, so I cross-referenced the processes/services running in Safe Mode w/ Networking against my normal startup, guessing something else was at play.After some poking around, I discovered that disabling the Server and Browser services permanently fixed the issue of instant connection death. But the initial problem I described still remains;random, less frequent internet connection drops.
I am experiencing random disconnects from the internet -- they have been occurring about 1-3 times per day, although I've just had four in the last 20 minutes.
ISP: Wow! Cable - 15/1Mbps
Modem: Motorola SB6121 (new)
Router: D-Link DIR-655 (new) Firmware 2.00NA
When the internet disconnects:
- Both the LAN & the WAN are affected, but I do not lose any wireless connectivity with the router itself.
- I am able to log into the router wirelessly but cannot access the modem.
- If I plug my laptop directly into the modem, I can connect to the internet.
- When I reboot (using the on/off switch on the surge protector), everything comes back up.
There are a couple of other wireless routers nearby with fairly strong signals, but they appear to be running on different channels.
My phones are DECT 6.0, so there shouldn't be any interference problems with those.
I've been poking around this forum, and have already made some setting changes that seem to be consistently recommended:
- Ensured DNS IP addresses are being filled in under Setup/Internet/Manual
- Turned off ALL QoS (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
- Turned off Advanced DNS Services
- Turned on DNS Relay under Setup/Networking.
- Setup DHCP reserved IP addresses for all devices on the router.
- Ensured devices are set to auto obtain an IP address.
- Set Firewall settings to Endpoint Independent for TCP and UDP.
- Using mixed G and N signal mode
- My security setting is WPA-Personal. WPA2-PSK
I have Windows XP Pro SP3. After a random period of maybe 30 mins to a few hours, my internet connection seems inexistant. PC reacts like there is no internet cable plugged in. I've checked the ipconfig command in command prompt before my internet shuts down and after and there was a change. A few lines(IPs) were missing after my internet fell.

When I get the lag spikes, everyone who is using my internet, also gets it the same time as me. So my computer is not the problem.For example: I am just running, shooting people (online), and then, randomly, people are running on the spot for like 3 seconds, and then they teleport somewhere in front of them. And then it goes back to normal, then it happens again. It will happen 3 times.
View 11 Replies View RelatedAt first it seemed to happen everyday at the same time, but now seems completely random (happening twice a day somedays). At some part during the day while the user is busy with this system it drops the network connection. The ONLY way to get it back is by restarting via the reset button. Shutdown or even logoff just hangs. Nothing regarding that card will work or respond, you can not even disable and re-enable. I can however get the wireless to work without restarting. I've done everything I could possible think of including format and re-installing Windows. Something new I've noticed is that the user always has MS Access (in runtime mode) running while network goes down and then you can not end that process.
View 3 Replies View RelatedI have been having intermittent wireless trouble. This includes Ping spiking, Wireless network drop-outs (The network stop appearing on available network list) and packet loss. This is all completely random (though very common) and is frustrating to say the least. As far as I know, the problem is not nearly as bad on other devices in the house , so I suspect that my network card has become shoddy. I have tried updating,removing,and re-installing network drivers to no avail. I have also used cmd and I have pinged 192.168.1.254, which shows random ping spikes, and some packet loss as well.

View 1 Replies View RelatedRecently I bought a new PC to replace an old laptop that I use in my bedroom. However, initially I couldn't pick up my downstairs router signal. So, I bought a new wireless network card and STILL didn't pick up any signal. I then purchased a Netgear WN200RPT and everything seemed to be ok while using that to repeat the signal up into my bedroom. Then, suddenly, it all stopped working. The WN200RPT would, although showing a full internet connection with no yellow ! or red x's, it would never ever load webpages. So, I removed it and put it back in its box. Then, for some unknown reason after a Windows 7 reinstall, my network card started picking up the signal from my home router and had a good speed and signal. This worked fine for a month or two before it started playing up again. It would randomly slow down and stop loading webpages, or completely lose the signal and show a red x, stating that no signals could be found. The strange thing is, all the other PCs in my house connect wirelessly fine, and so did the laptop that was in the same room as this PC. After a system restore, the internet started working again. Then it stopped. Another restore later, it works. Now it's intermittent again.
View 3 Replies View RelatedWhen doing anything on my PC, gaming, browsing, whatever, I will have random disconnects for a few seconds and it will reconnect. I don't get the "your network cable has been unplugged" message, it just stops working for a second or two and starts working again. This has been happening for a few months after a fresh install of windows xp and I haven't really tried to fix it.Every other computer in the house is fine except this one, it can't be the modem because a new one was installed a few days ago and its the same problem. The router was reset within the last week as well. I think the problem is with this computer alone but I don't know where to look. The problem didn't happen for a few days after I put a new network card in, but soon after it continued happening. I also have tried a few different CAT5 cables, even the XBOX one but nothing resolved the issue.
View 4 Replies View RelatedI have been experiencing random disconnection from the internet completely out of the blue lately. Router has worked great for a long long time. Now it just drops connection and is down for about a minute and then I can reconnect or reload a webpage.I have my xbox live and PC wired with a laptop wireless. It drops everything at the same time everytime. I hardwired my xbox to the modem and gamed all day. I would assume this could eliminate the modem as an issue. There isnt any inconsistencies with the router's colour or lights to my knowledge either.
I put a new Ethernet cable from modem to router to try and I thought it fixed the problem but it lasted problem free for about 6 hours then it crashed.
I am having an issue with 3 xp pc's in my network loosing connectivity to the file server. There are 4 network drives mapped to a win 2k3 server, when the user logs in everything is fine, after a while the network drives become unreachable and gives the following error - An error accrued while reconnecting (drive letter) to \servershare Microsoft windows network: The local device is already in use The connection has not been restarted” This happens from any user on only 3 boxes. The rest of the network is fine. These 3 are networked via a switch, I swapped that out for another hoping that might fix it, but nothing.
The other odd thing is the same time that the network drives error out it seems that DNS stops resolving anything outside my network. I can still ping the router and other pcs on the LAN but DNS fails to resolve any names for IE, and nothing outside the LAN can be pinged, no Google, no 8.8.8.8. How ever restarting fixes the issue for a short while. There have been no network changes and all systems are fully up to date as far as patches go. I was thinking it's got to be a ether a DNS issue (the file server is also the Active Directory Domain controller) or something in to do with the router/fire wall we use (it's a Cisco ASA 5005).
I have fiber optic Internet with static ip and keeps disconnecting at very random times. It started 3 weeks ago, before it worked perfect. Most of times dcing 3 times per hour. But sometimes working for hours without dcs. Usually disconnects only for half minutes then reconnect, it can be very annoying. The provider keep saying that need change router. I'm tried three different of routers already, but keeps disconnecting. I'm tried connect the net directly into my cpu, without router, but not worked, dc-ing too. I tried ping the default gateway when its disconnected, and its saying: request timed out.What else can i try? It should be, that the provider has too many clients, and their router collapsing?
View 2 Replies View RelatedI have a Dell XPS 410 desktop PC purchased in 2006 now running Windows 7 (32-bit) that is hard-wired to D-Link 825 dual band N router.
The Problem- The desktop, when actively using the internet, will randomly lose connection to the Internet, then by just waiting, it re-acquires a connection. When it does this it sometimes also disconnects other laptops that are wirelessly connected through the same router, or at least slows them way down. Also similarly effects a hard-wired X-Box 360 (either loses connection all together or, the games start to severely lag) much to the disdain of my game playing kids.

my internet would just at random STOP for like 2-3 seconds then catch up with itself. I have 3 computers, 1 printer, a laptop and an xbox all setup on a NetGear N300 Router. the 3 computers and xbox are directly connected to the router. the printer and laptop are wireless.The Road Runner Modem is a CISCO Cable Modem DPC2100R2. Now when this random STOP happens... on programs like Teamspeak peoples voices cut out but then quickly catch up with themselves. On Black Ops PC and Xbox everyone freezes for a few seconds then catch up to themselves and I'll get a connection interrupted. I'd be asking friends around me to see if they got that "Connection Interrupted" and they say no. On Rock Band 3 I get randomly disconnected from the game with everyone asking what happened...When this STOP happens... my computer doesn't give me any error message like "Local Area Connection is unplugged" or anything like that. I've tried checking my CISCO modem's log and it shows no problems.Last week I swapped out the Road Runner Modem at their swap shops to see if that was the problem. Obviously it isn't. The Router I had before the NetGear did the same exact thing except it was a westell...I've tried directly connecting the modem to the computer and trying that to see if there was some kind of miscommunication between the router and the modem... same thing.
View 19 Replies View RelatedI play some games online casually, primarily League of Legends, and about every second sitting the internet has frequent 'blips' of going down for long enough to make the game have connection issues. I've noticed it is the sending that goes down and if the receiving goes down at all, then it is very quick. (The game still plays and I see everything that is happening but cannot respond. This happens in Rift too the rare time I play it and the even rarer flash games I play). Though I have tried many things to fix this issue, it hasn't truly bothered me that much until recently when I realized I play even less than I normally would out of fear the game session will be ruined by the internet.About half a year ago the internet was in very bad shape. It crashed often and stayed down for a long time. My ISP is Comcast (Or Xfinity...), and it took me many weeks of harassing their customer support (off and on) for them to fix it. Then it ran smoothly for a couple months before it started having these blips.
The details:When it has a blip, before, during, and afterwards (I've sat by the modem to watch it happen), there is no indication of the internet having trouble on the modem indicator lights. Nothing changes, and they flash at about the same rate as normal. The router I have is a Linksys, and nothing seems to change on it either during a blip.I have the games port forwarded. All my firewalls including the windows firewall are off. I have updated my wifi and internet drivers on my computer and am using the firmware recommended to me by my ISP for the router.
I've been having some problems with my new custom built computer connected wirelessly to my Router. My router is an SMCD3GN. So it is a Router/Modem in one. I am currently using the Linksys AE3000 Wireless-N USB Adapter. I have had a past Wireless USB Adapter, & an internal Wireless network card. The USB quit working & in order for me to get it to work is I have to reinstall the drivers everytime I turn my computer back on. The internal wireless network card would randomly lose internet every 30mins - an hour. Being a gamer, this is very frustrating. So, right now I am using the Linksys USB, and I was just playing a game & talking to some friends on skype & I would lose internet for 2 seconds then it would automatically reconnect. So I am beginning to think that it might be my Router but I tried my USB on my laptop for like 10 mins (I disabled the internal wireless network adapter) & I went into cmd.exe and pinged google for about 10 mins, & it said "Request Timed Out." several times.
