I have searched and searched the web, contacted my ISP, and my router manufacturer and have not come up with a solution to this problem. Plain and Simple, quite often when I am trying to load any webpage, I have to press the refresh button to display the page (sometimes more than once). i live in Phnom Penh, Cambodia (from the U.S.)and just recently got internet service from an ISP named "Digi." This ISP uses PPPoE, which for some reason was a problem with my Apple Airport Express (worked well a few days, then the internet stopped working from DNS errors). I bought a new wireless router directly from Digi, which is a TP-Link (model TL-WR841N). Upon hooking up the router to the modem, the internet worked, but this new problem started forming, needing to reload pages several times. Side note: my internet speed is 3mbps so it's not an issue of speed.
What I have tried: First, I tried several websites to see if it occurred on more than a couple it does. Second, I tried different browsers and different devices. The problem persisted on Safari, Chrome, and Firefox on my Macbook Pro. I deleted cookies and chaches to no avail. I have never installed extensions and have them disabled anyway. This problem also occurs on my iPad and iPhones. I then thought it may be my new router, but upon connecting my Macbook Pro directly to the modem, the problem, yet again, still persisted. I have rebooted the modem with still no change. I contacted my ISP, who said that on their end, everything seemed to work fine. Upon searching the internet, all I've found is suggestions to change my browser (check); delete cookies, caches, and disable extensions (check); or change my DNS servers address to public oneslike 8.8.8.8, 8.8.4.4., or 4.2.2.2(double check). Still, these solutions have given me no luck, and it is still frustrating to have to reload webpages, especially when it's a login page.
Our router suddenly reloaded. Below are the crashinfo obtained:

I have done so much research and tried almost everything on these forums, but still the internet wont load on my laptop. It is a Acer mini with Windows 7 starter. The other day the internet just stopped loading pages. It shows that it is connect to my router, and when I try to go to a page, it just says loading. I tried to connect with the ethernet chord from the modem and it does the same thing. I think there is a connection, but just wont load pages because the avast will update the virus definitions. I've tried to update the drive, reset the ipconfig. One thing I noticed is that the ip6v says not connected but the ip4v says internet. If I can do anything to get more info I surely will post it back up here, I just need to get my connection back up
Moving into a new spot and some of the computer will be forced to go wireless. Is it better to have an adapter or an actual built-in PCi card?We play a lot of games, so that is my main concern, will we notice a big difference? The router that I am using is a WND3700 with latest firmware update.
I have a WS6509-E which is running on below IOS had a software reset yesterday, however I am not able to identify the exact reason for this to happen.

I have a cisco 2821 router in rommon and displaying the message '' softwre forced crash '' and '' checksum error'' .I tried to do rommon tftpdnld but as the image is self decompressing into the ram it again crashes with the same error although i have done it with various valid ios but in vain.
Our router reloaded yesterday with a Software forced crash . I ant to identify the reason for the crash and also the fix for this problem . Attached is the crash info output .
I've run into this before, but I can't figure it out this time. Running Windows XP SP3 on a Dell Vostro 1510 notebook with a Linksys WRT54G router wireless. Using Dells Network Assistant for management, so I cannot get to Windows wireless connection management directly.I have a connection to the internet with a Security Key. When I bring up a browser (Firefox or IE) I cannot resolve to a web site. There is a Cisco login screen that is forced. It's from a previous wireless connection on a different network at a different location.
Our switch had a little crash-fest this morning at 2:30 AM. I did find a web page about diagnosing Software Forced Crash Exceptions, but it did not look like ours was one of the more easily-identifiable ones.
It may be worth noting that we've only used this switch for about a month, everything seemed fine until now. When we got the switch it did not have any GigE modules, and this week we put 2 into it and have been using them for 2 servers.
It looks like the switch was crashing repeatedly over a period of 20 minutes, and then it stopped and normalized. In the logs of the router that this switch uplinks into, we could see the ethernet port flapping during the time that the switch wasn't reachable.

In our project, we had to configure PAGP between catalyst cisco 3110. there is no problem in configuration of PAGP and everythin is ok,and channel is up.but after reload cisco, chanel can not be up and between switches all packet are in loop between 2 switches.in order to solve this probelm I have to shutdown all port and again create chanel for every port.
I have cisco router 3925 and i add install HWIC-4ESW, as i sew on cisco documents you can hot swap the hwic without reload the router but i it's not working at all. How to do it ?

From PEC training - Cisco says to perform a proper ASR 1004 shutdown by executing 'reload' , then wait for bootstrap message to appear, then [before commencement of unpacking of the IOS] turn off the power switch. IS THIS ACCURATE. Anyone have any doc related to the recommended POWER DOWN process on the ASR 1004. We have a UPS cutover coming up and I want to be ready to power down and restart the new ASR 1004s we have - properly.
I've got my Cisco 2901 with Security license setup and running (seemlingly) great ... However, with one issue that's scaring me a little bit.After a reload or power-on, the router starts up and begins trying to negotiate the three VPN connections. All three connections are to SonicWALL routers (1 NSA-2400 and 2 TZ-100), and those are configured with "Keep Alive" enabled.The problem that I'm having is that the VPN connections do not come up. When I do a 'show crypt session', it shows all IKEv1 SA as DOWN-NEGOTIATING. It will stay this way indefinitely. The only thing I can do that works is to log into each respective SonicWALL, disable the particular VPN policy, then re-enable -- and then it works no problem.
The only thing I can think of that might be affecting the success would be the "Keep Alive" enabled on the SonicWALLs ... But at this point, I'd rather not disable that until I know more about what may be the cause. (Definitely can't take down a tunnel or play around during production hours for testing.) There is some random stuff in there too, as I was attempting to provide access for myself when remote through VPN. Here is my current running configuration. [Code]
I've just purchased a new Cisco 881.I'm using NAT NVI for my inbound static mappings. However, regardless of the fact that the config is saved to nvram, after a reload of the router, the NAT mappings are setup as traditional inside/outside mappings. This means that inbound connections in to the router on the required services fail, until someone logs on to the router and re-applies the NVI mappings.
Here's a sanitised version of my startup-config:

Something strange is happening to my Cisco 1941W. Every time I reboot the router i loose the running configuration of the service-module (Access Point module). The weird thing is that the router's configuration remain the same. I made sure i save the configuration by issuing the wr command on the service module console but still happens. My router's current IOS version is 15.0(1)M1 and my AP's is 12.4(21a)JA1.
I also did another test by making sure the startup-configuration was identical to the running configuration and when I reload the router still happens.
SSH has been enabled on our one and only 4507 switch for several months and working fine. A few weeks ago the switch had to be reloaded and when it was back online I couldn't SSH to it. When I connected via the console and typed "show ip ssh" it came back saying I needed to generate the keys. Did that and it starting working again. The same switch had to turned off and on the other day due to a power down in the server room and when it came back the same thing happened again!!
The version of IOS is: cat4000-i5k91s-mz.122.20.EW
We had an power shutdown activity last week, due to which one of the core switch was turned off and ON .After the core switch was turned ON, we had found some of the ACLs missing which were bounded in VLANs. We had given write command before this power shutdown activity.We need to find the root cause for the same.
I have a cable from an SFP module in a WS-C3750-48P with 12.2(55)SE1 running to a Gigabit port on a Cisco WLC. After the switch recovers from a power failure, the gigabit autonegotiation fails. The cure is a long drive to unplug and reseat the SFP. Note this happens at too many similar sites for this to be a loose connection. Interface shutdown then 'no shutdown' is not sufficient. The state is 'line protocol is down (not connected)'. Interface is configured for switchport mode trunk (auto speed, auto duplex). Command 'switchport nonegotiate' makes no difference. Is there a more powerful command than 'shutdown' which might toggle the interface signals? Is there some way of resetting the SFP? sh int gi 1/0/1 displays 'media type is 10/100/1000BaseTX SFP' and zero packets received.
Recently, we had a 3750X stack of 9 switches reload with no information as to why. Our syslog server received no spurious errors regarding the cause nor did the location lose power. The UPS to which it is attached logged no glitches relating to power. Other cisco devices (router, other switches not in the stack) did not reload. No one was in the MDF during this time. We self insure these line of switches so a TAC case is not an option at this time. Any forensic tools that I could try in an attempt to narrow down the cause.
Last night, the C6509-E do a unexpected reload. In the crashinfo, I can see that the last error message before the reload, was as follows: %C6K_ PLATFORM-SP-2-PEER_RESET: SP is being reset by the RP
I consulted the cisco website about this error message and what I found was the following:C6K_PLATFORM-2.
I've been having a problem with a brand new SG300-10 switch that I posted about yesterday. I checked the firmware and it was at 1.0.0.27 and the lastest is 1.1.0.73. So I backed up the current firmware and loaded the 1.1.0.73 version and it seem to be CLI based only, with no web GUI.
If so is there an easy way to reload the 1.0.0.27 using the CLI? There is nothing in the CLI docs that I can see unless it's buried.
The release notes for 1.1.0.73 don't say it's CLI only either, maybe something just went wrong but the CLI seems to be functional.
I have Build a 5508-HA Cluster (7.4.100.0) , hat to reboot this cluster due to Licens install.After the reboot atleast one of the SSIDs was not broadcasting anymore, even the checkbox was checked.
What did I do:
Installed the Licenses @ Freiday 12:00 @17:15 reload active WLC, wait till controller is up again (a few minutes pingable) @17:25 force failover to first controller. check a few SSIDs but not all, those who where check are ok. @monday 07:00 clients complaining not seeing the SSID (some where connected)

I don't have a USB to serial adapter handy, and was wondering if had success breaking to the Rommon prompt during system reload (boot sequence) using the USB console on a Cisco 1941 router?
Our costumers has implemented 2 AIR-WLC4402-50-K9 with Software Release 7.0.98.0, the wireless infrastructure consist in 2 Root-Mesh-LAP and 8 Mesh connect over-the-air to deploy outdoor coverage.
All the LAP are Aironet 1520 Series Mesh Access Points with equipped with 3 antennas for 2.4GHz and 1 antenna for 5GHz (backhaul).For one year all seems to be ok, yesterday after a power outage of one Mesh-Root-LAP, 5 Mesh-Lap continues reload each 10-12 minutes, on the WLC Log you can see event like a reboot from AP Console, on the LAP console i can capture this event before the reload:
Log on LAP Mesh %DOT11-6-GEN_ERROR: Error on Dot11Radio0 - Not Beaconing for too long - Current 0 Last 0 %SYS-5-RELOAD: Reload requested by Dot11 driver.

Reload Reason:Radio Not Beaconing for too long ....*Sep 1 16:05:43.399: %LWAPP-5-CHANGED: CAPWAP changed state to DOWN
What does it mean? That the beacon signal trasmitted from Root-Mesh-LAP cannot reach the Mesh-Lap and so the Mesh-LAP force a reload?Where we should search the cause? In the power instability or in a interference on the 5GHz radio interface?
On one of mesh Lap I found a strange reason for a releoad:AP1780-Mesh uptime is 11 hours, 10 minutesSystem returned to ROM by power spike

I reloaded a friend's Dell Latitude D600 laptop with Windows XP Pro 2002 service pak 2 and loaded all the drivers from the Dell support web site. Everything is working now except the WiFi does not get on the web. I have a strong signal, and it says Connected, but also says "Limited Connectivity". Another laptop works fine on this same wireless router, so I know it is a problem with the machine. I loaded the required driver from Dell.I have a built-in Intel PRO/Wireess 2100 3A mini PCI adapter. Here is the IP config:
Windows IP Configuration Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : IP Address. . . . . . . . . . . . : 192.168.10.108
We have a backup sup 720 which has a 2 gigabit ethernet though port channel, to another chassis. Suddenly UDLD detected an error and got into err disable, then this err disable didn't let the interface set to DOWN, and created a switch loop, then our Supervisor reloaded. I'd like to know what could have caused this reload. In my opinion could have a been the switch loop, but also I've been checking from the output interpreter the show tech and might have been a bug, the only one that could match in IOS version 12.2(33)SXH, is this one: url...
We're going to disable err-disable next time I guess and recover the link manually, apart from that what could have made the sup for crash and reload?
