Ill get on my laptop and it will connect for 45min-hour and then it will disconnectEverything says connected on the laptop and the router and modem are connected and working. I have tried restarting my router and modem and even clean installed windows and reinstalled drivers. Nothing seems to work. Im posting from my old laptop and it seems to happen on this computer as well. This has never happened before.
View 9 RepliesRecently 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 RelatedBasically i'm an employee of a Pro-Gaming team, and as a Job I stream games live, as well as upload game videos to youtube. I've been encountering a problem for a month or so now and had little success of fixing it, which is costing me quite a lot of money and viewers! Basically, I use a program called Xsplit to stream to a website called Twitch.tv (no-one else i've spoken to has the problem I have). I will randomly disconnect/reconnect instantaneously which puts my stream down for 5-10 seconds at a time, then goes back up again. Ultimately the viewing experience is ruined by this and I am on the verge of being replaced!The problem can occur either once a week or once every minute.. it just does it whenever it wants. I have 200mb/10mb internet so my upload should in theory not be an issue.
Things I have tried and done so far:
- Replaced the Ethernet Cables.
- Replaced the Routers.
- Bought a Network Card to try as opposed to my Motherboard port.
- Reformatted my computer and installed a different version of Windows 7 multiple times.
- Spoken to Twitch.tv and Xsplit about their programs as well as used multiple versions of the Xsplit client.
- Spoken to my ISP who say everything is fine.

2 Site to Site VPN tunnels has been established, it is a hub and spoke topology. The hub is ASA5520 and the 2 spoke are a 1841 and 1801 router. The tunnel is able to pass traffic, it's a full tunnel VPN.The tunnel randomly disconnect for no reason. When I check the logs I can see some errors :
%CRYPTO-4-RECVD_PKT_INV_SPI: decaps: rec'd IPSEC packet has invalid spi for destaddr=x.x.x.x, prot=50, spi=0x5F822579(1602364793), srcaddr=y.y.y.y
%CRYPTO-4-IKMP_NO_SA: IKE message from y.y.y.y has no SA and is not an initialization offer
The actual address have been replace by x.x.x.x and y.y.y.y. I frequently have to peform clear crypto isakmp on the spoke routers to revive the VPN tunnels. Is there a way the tunnel can be re-establish again without manual intervention?This keep happening on a random basis and I have living with it for years. I have looked at cisco website troubleshooting tips and but no luck in finding out how to resolve it.
Below is my config on one of the spoke router:

We have computers that are connected to a switch stack of 3 - 3750 switches. Randomly, we experience pcs that fail to communicate on the network. At first thought I figured the port went into err-disabled state, however the port shows up fine on the switch and moving the pc to another port on the same switch in the stack fails to fix the problem. To add to the confusion, if I immediately connect a different machine into the problematic port the newly connected machine has no issue and operates normally. Connecting back the first machine still results in no connectivity.
The only way to gain back network connectivity is to move the pc to a different switch in the stack. shut/no shut doesn't work.The IOS the stack is running is 12.2 and the switch ports are configured using cisco port macros.
here is how all the ports are configured.
switchport mode access
switchport port-security
switchport port-security aging time 2
switchport port-security violation restrict
switchport port-security aging type inactivity

The issue is a odd one, I will be playing a game League of Legends, Star Craft 2, Diablo 3, or Tera and I am in Team speak then about 5 minutes to an hour I get "Connection has been lost". I am either booted from the game or Team speak, never both. It's completely random when this happens and at times it takes a while (10mins at the longest) for me to log back into what ever program I have been disconnected from other times the reconnection is instant. I have gone through forums, talked to support for the games, had my ISP come out and test my lines and replace my modem and network card, Ping tested, Speed tested and the results were stellar, but I still have the problem and so I feel that the problem is on my end. I have a self built machine, My OS is Windows Vista 64-bit, Mobo-EVGA 132-CK-NF79 2, Processor-2.85 gigahertz Intel Core2 Quad.

View 9 Replies View RelatedI've got a setup like this:
WLC 5508 v7.0.98
6-7 Autonomous upgraded to lightweight APs - 2 * 1231G while the rest are 1242AG
3 dynamic interfaces, 2 to Corp (diff VLANs) and 1 to Guest
4 WLANs binded to different interfaces
2 to the Corp interface Vlan X
1 to Guest
1 to Corp Vlan Y
DHCP for Corp is provided by their own Win DHCP server while controller is the DHCP server for Guest. Lease time is 1 day.
My problem now is, some clients, at random, loses their IP after being connected to the network. They get a 169.254.x.x. They connect to the Corp network OK, no browsing issues but after a while, they lose their IP address.
They can either wait for a while before getting an IP back or just simple renew their IP on their machine.
I've tried increasing the threshold values in the Local EAP to double its default values and also setting the WLAN session time out values to infinite. However, these 2 didn't work. I'm still having clients that occasionally lose their IPs at random.
I've also noted that this affects clients with WZC wireless drivers and not others e.g. Intel Proset.
Network running about 60 computers, most of which are running windows 7 professional. Some are on a domain, some are not.At (seemingly) random times, some computer on the network will lose the ability to browse websites (including the web interfaces of networked devices). I can't identify what circumstances cause this to occur. I only find out about it when someone calls me.From the affected computer:I can ping sites I can ping our Cyberoam UTM (which acts as our DNS, DHCP, and firewall)disabling/enabling connection doesn't fix the problem releasing/renewing ip doesn't fix the problem flushing dns doesnt fix the problem uninstalled antivirus on two test machines, problem still randomly manifests.replaced the Cyberoam with newer model users have claimed that if they wait a long period of time (40+ minutes) the problem sometimes resolves.rebooting the computer resolves the issue until it randomly occurs again changing the computer's mac address also resolves the issue until it randomly occurs again.

View 1 Replies View RelatedI got new internet connection some days back (like 3-5 days ago), and since then, when I try download at night time when I'm sleeping, my internet disconnects me? I'm downloading with JDownloader by the way. I didn't get "new" internet, well.. I basically did, but yeah... This is how I got "new" internet.I used to have same ISP, but it was 24mb internet, and gave just 12mb to be honest, so I got 100mb instead. But since I got this 100mb internet connection, it disconnects me at night time, I don't know why. I've tryed to lock my PC as I download, I've tryed to keep completely on the whole PC, but still no. Always disconnected when I wake up.
Is there something I could do about it? When I had the old 24mb internet, it didn't disconnect me really... never. Just once in a while, like once in month or something but that ain't much. Is there something I could do?My download speed, it should give me 8-12mb/s (I'm not sure though), and I can't do speedtest.net thing right now because I'm downloading at daytime then instead of night time, because I can't download at night time... But yeah, my download keeps jumping from 500kb/s to 12MB/s (12 mb/s is more true than 500kb/s), shouldn't it give me the full speed all the time? Or keep it above 6mb/s anyways? Not like 500kb/s - 5mb/s that it usually is. There's just 1 LAPTOP (I'm using wires, PC you know) connected on this very same internet too, but it's wireless. It keeps jumping, either somebody uses the laptop or not, it doesn't matter

View 2 Replies View RelatedI am an unlucky person who still has a belkin router. Not only do i have a belkin router, my PC is also connected via 2 switch boxes all ethernet cabled together in and around the house.
I am unable to forward and ports succesfully because after i have saved the settings i check it with a port checking site and it says they're all closed.
I have also been getting disconnected from my router when its under stress (Most recently playing League of Legends) but my Dad's Pc (Which is only connected to the Belkin) still stays connected and hasn't experienced any disconnections.
My router model is F5D7634-4 v2, DHCP is enabled but only my Dad's PC appears, UPnP is enabled but doesn't seem to work and my fireware is up to date.
I used to have a different router before this one which never had these disconnecting problems.
My Internet will disconnect & then reconnect constantly. I have 2 laptops & they are both on my home network & I have no trouble with the other one so I assume there is nothing wrong with both the Internet service & router. The laptop with the problem is an acer/aspire 5720z. The Wireless Network Adapter is a Atheros AR5007EG. When I go to the Adapter Properties the status reads "The device is working properly". When I go to Control Panel>Network & Sharing Center my Wireless Network Connection Signal Strength reads Excellent. The operating system is Windows Vista Home Premium.

But whenever I try to connect again it just says "Windows was unable to connect to your network".I have to physically restart the router to get the devices to reconnect, and having doing so on a regular basis has meant my IP Profile has been dropped at my exchange as it thinks it'll "keep a stable connection"?Would it be worth changing the channel and security type?
