Cisco WAN :: SR520w Ports Stop Working After A While
May 11, 2012
I have setup a Cisco SR520W and everything appears to be working. After a few hours, it looks like the WAN port stops forwarding traffic to the Internet gateway IP of the device.
If I unplug and then plug in the network cable connecting the WAN port of the SR520W to my the modem, traffic startings flowing again. Also, if I restart the SR520W, the traffic will flow again.
Here is my config file:
Building configuration...
Current configuration : 17830 bytes!version 12.4no service padservice tcp-keepalives-inservice tcp-keepalives-outservice timestamps debug datetime msecservice

I've lost connectivity with all but one of the ethernet ports on my E4200 router. My desktop PC was connected to Port 1 but stopped working. Network troubleshooting via my Windows 7 Dell 8300 said I was not connected and to check the cable. I did that with several different cables and tried the usual router and modem reset. Only through trial and error did I find that I could connect to port 4 which is why I am able to write this post. What could have changed to disable ports 1-3 and can I get them working again? No issues with wireless connectivity.

Whenever I start a Cisco VPN from any machine on the network, DNS requests to the DIR-655 stop working. If I reboot the router, DNS starts working again (the VPN was left on). Why starting the Cisco VPN would freak out the router?

Router: Linksys Wireless-G Model: WRT54G v8
Wireless Adapter: Belkin model F7D1101 v1
I have two computers in my house, one is set up directly to the modem/router and the other (in my room) is set up wireless using that belkin adapter above.
Everything has always worked perfectly, but two days ago things went haywire. If my PC connects to the wireless, then it makes the router stop working for the other computer and any wireless devices I have. As long as I don't have my PC connected, then things run smoothly and there are no problems, so it's definitely stemming from my PC?
I thought it might have been the router at first, so I switched it out and it worked fine for over 24 hours, but then the problem came back.

I was trying the following actions:
1.- dmgtd stop -> to stop daemons
2.- dmgtd start -> to start again the daemons
And the DCR Server does n´t start up automatic.
Then I try this:
1.- pdexe DCR Server
And show this message:

and don´t start up the DCR Server.

Yesterday my wireless internet just appeared to stop working completely, it has always worked fine up unti now!I have checked all the usual issues, it is nothing to do with my router as i can use other laptops/desktops to access the internet fine.I am using a Pavillion DV6-1215sa which has a Atheros AR9285 802.11b/g WiFi Adapter.It has full strenght but just says Limited Connectivity, so it is picking up the wireless network but wont actually let me connect to the internet via it.
I am able to access the internet when i hard wire the ethernet cable into my laptop, but the just wont work for wireless.I have tried lots of different suggestions so far, but still cannot access the internet.

Once again I'm stuck to tethering on my phone due to my router deciding to call it quits for the random moment. I cannot access its control panel, the network just goes kaput. Given that I don't have access to the router since it's part of a double house (the side I'm not on of course), this is getting beyond irritating to reboot it when this happens as that is the only way to fix it. The connections are even wired, too. What kind of money does it take to get a router that is going to STAY on and just work? I'm ready to dump some serious cash into this at this point because this happens at least twice a week anymore. I just want a router that works. It needs to be wireless as my neighbor does use his kindle on it every once and a while.

I'll be downloading off of newsgroups and be pulling 3-4 MB/sec, no problems. My downloads are charted so I can see my speed never drops at all.but my web browsing will just STOP, for ~30 seconds. I'll have multiple tabs just STOP and crap out, while my downloads run fine. This also happens when I'm not downloading, so I know it's not a bandwidth issue,i assumed it was a router issue until I replaced my router and am getting the same issue.

Model : TL-WR741ND
Hardware Version : Not Clear
Firmware Version :
ISP :
after year and a half of using TL-WR741 ND router, it suddenly stop working during the night. I have no problems with router before this happened (I think only one or two reset in 1 year and 6 months). System led light does not flash (some sytem error) and I can't access to 192.168.1.1 router setup site. I tried almost everything, unplug power, reset etc. for almost 100 times, reconnect the router with modem and PC in all posible ways, but still can't establish connection or even access to router's setup. Obviusly internet works fine?

After an hour on the phone with the Linxys support people I'm feeling like I've been scammed.I have a 2 year old, almost to the day, Linxys Wireless-N Broadband Router, model # WRT160NVZ, which decided to stop working today. I contacted Linxys support and was told since it is 2 years old it's no longer under warranty, ok. If I choose I can pay for a service call and the tech may be able to fix the router, no guarantee. I had another option to purchase a service plan but again no guarantee repairing the router. My third option was to purchase a brand new wireless router for a discounted price, if I chose this option the tech would attempt to repair the router at no charge. I expressed my concern that it would take a few days to receive the new router and what would I do while waiting. I was then assured the router I have now could be repaired and would be able to hold me over until I received the new router.So I chose the 3rd option purchasing a M20 wireless router to be shipped to me within 3 days. After providing my credit card number and billing/shipping address the technician was now able to work with me in trying to repair the current router. He had me access the Linxys website, he instructed me in resetting the router and resetting the settings for it on the website and PRESTO, my 2 year old router now works again.but feel that this is a scam, programmed in the router to occur within 2 years of purchasing where the settings entered no longer work but once changed works perfectly well.

Perhaps once a week my ethernet port stops working. That is, it is still displayed as 'working properly' in the device management screen, but it is unable to connect to dns. System restore does not solve this problem. plugging the ethernet cable in and out (10 times) does not solve this problem. Modem reset does not solve this problem either. I decided that perhaps ethernet controller is faulty, or perhaps the ethernet port in itself- so I bought a 'usb to ethernet' adaptor and surprisingly the internet connection problem persisted (during the instances when my laptop ethernet port had problems connecting to DNS, the adaptor was also unable to connect to internet).
What does solve this problem is this: I have another notebook - I plug the ethernet cable into that computer. Obviously, internet works without any problems with my second notebook. After that, I plug the ethernet cable back into the laptop which is now unable to connect to DNS. Quite often the Not being able to connect to DNS issue still remains the first time I do this, so I have to connect ethernet cable back into my second notebook and then plug it back into the notebook with a connectivity problem. After I do this 2 or 3 times, my windows 7 laptop is finally able to connect to internet.

Few days ago the wireless in my son's Dell Inspiron 620 went bad. It does connect to my old router (WEP), but speed is terrible and connection goes bad after some time. I can also see my modern router and enter the key successfully (WPA2), but it won't connect. Connection to both routers went well for months before, and still goes well from all other devices in the house.
I read the issue with McAfee that was posted late August and followed the steps. Connection in safe mode didn't work. Then I removed McAfee from the PC, no difference. Then I restored the PC to a couple of days before the issues began, removed McAfee again (as it came back through the restore), no difference.
I reinstalled the drivers of the Dell wireless card, no difference.

I'm having problems connecting to the Internet using the wireless adaptor - it will connect initially but the connection is very very slow and then will eventually drop out and stop working.When I connect using an Ethernet cable, there are no problems whatsoever so I know it is not a service provider issue.I have updated the BIOS to A11 and all drivers are up to date. The wireless adaptor is Intel Centrino Wireless-N 1030. [code]

I have a switch containing 48 connections. I have a patch panel that links to lots of access points in my building. One access point was not connected but needed to be but I didn't have any spare switch ports. I therefore reconnected switch 23 from one position (and thus one access point) to another position on the patch panel. Everything worked fine and this new location had network and internet access. Then however a few weeks later I had to change it back so i changed the connection of port 23 to the old position on the patch panel. When i did so port 23 showed a red light and then no light. Later I had to change it back to the other location but when i did so port 23 now shows no light whatsoever. It's as if the connection port just stopped working. Now both the old and new access point locations have no connection and I can't understand why.I tried rebooting the server but no luck. I tried connecting that access point through the patch panel to a different connection port but still no luck.

I am trying to test the gigabit ports on a Cisco 2950 switch. 1000Base-SX. I have the internet or dhcp server connected to port 24 on the first switch and my pc hooked up to the (any) port on the second switch. Both switchs are connected with a fiberoptic cable with MTRJ connectors on either side.
Now when I use gi0/2 on both switchs all works fine. I get a dhcp address from the router on the other end of the first switch. but when ever I include gi0/1 on either end of the fiber optic cable neither of the ports will initialize (neither of the leds above the ports light up). I have deleted all the config files before booting up the switchs so they should have a default blank configuration.
When looking at the Http web page for the switch I dont see any issues with the port. what can I do to make sure these ports are working or can be configured?
I will not be able to post back any more information about the switch until next tuesday. Im off till then.

I have two switches, WS-3750-24PS-S connected in two cabs via fiber. Patch panels at both ends with patch leads. Used tester to confirm end to end fiber connectivity. When plugged in, one switch lights up the other does nothing.
Ports are as follows:
interface GigabitEthernet1/0/2
switchport trunk encapsulation dot1q
switchport mode trunk
same at both ends. Tried both GI ports same result. swapped transceivers over and the same result, (one switch lit one not - the same switch in both cases). put both transceiver in each switch, (gi0/1-0/2 in a single switch). on the one that lights up in the original scenario we get link on both ports and they come up, on the other nothing happens. shut down both ports on the malfunctioning switch and no shut them, no change.
Show transceivers doesn't show transceivers on the malfunctioning switch, and no attempt is made to bring the ports up if the fiber is removed and replaced.
it is almost as though the two gb ports are kaput. Anything else I can try?
