D-Link DIR-655 :: DNS Server Timeout / Lockup / Crash
Dec 12, 2010
So I just bought a D-link DIR-655. It's a B1 hardware with the 2.00NA firmware. After a few hours the DNS server in the DIR-655 stops responding. This happens on all of the PCs connected to it (both wired and wireless) who have their DNS server set to 192.168.1.1. The only way I've found to recover is to reboot the router, change something in router's the configuration causing the router to re-initialize, or to ping an external site from the ping test console. When this happens the external ISP DNS server are still working (confirmed by NS lookup testing manually setting them).
I have many WiSM WLC's running 188.8.131.52. One WLC was rebooted few days ago but there was no crash file and nothing in logs say why this issue happened.There was a power problem at the same time the WLC rebooted (some switches and PE's was rebooted as well) but if it is a power issue why only one WLC inside the WiSM rebooted and the other WLC is still working fine with no reboot?I have 5 WiSM modules connected to the same 6500 box, only one WLC was rebooted which indicates a crash but no crash file registered for it.Is there anyway I can find the reason why that WLC was rebooted?
Just purchased a RV082 and once I switched a bunch of users over to it I can no longer access the web admin section. I have tried using both IE and Firefox and have used multiple workstations. I get to the login screen but it doesn't get any further. I am running the latest firmware v184.108.40.206-tm. It works for a while then just stops. The only fix is to turn off the device and back on and then it starts working again.
I've seen this issue on other small business cisco devices and had to stop using this because of this issue and switch to a higher grade cisco product but was hoping that this particular issue would have been resolved now across cisco's products.
I have an sg300-10 unit. I have recently swapped it into my LAN network to replace an aging switch that was exhibiting problems.
The SG300 is reporting near constant 100% cpu load with 11pps input. there are only 3-4 active ports on the switch at a given time. One of those ports does lead to my router and another switch with another half dozen devices.
By itself this doesn't concern me overly much, but I have found that the SG300 is occasionally freezing up for about 20 minutes then restarting. Syslog and SNMP traps don't appear to provide any hints as to what is going on.
I have tied my switch into my monitoring system (packettrap MSP, so if there is something I should be watching that I am not, that would be good to know). I am still troubleshooting getting all the monitoring functions working as well.
So, I have some questions there as well, which OID should I be monitoring for CPU utilization?
problem started a few months ago. wireless kept crashing. tracked it down to seeing it crash when certain Win7 Dell laptop tried to connect. (Laptop is company owned with standard type of corporate AD authentication and image) my wireless setting use WPA2 personal with AES encryption. use both N & G, auto rate and scan.any time this laptop connected the wireless crashed, other devices didn't show SSID (both main and guest)But wired connection continued to work fine.
First of all i do not have that much know how within this field (Although i work for an ISP)
There seems to be a problem with my DIR-655.
#1. As we speak the router is taking down and setting up the connection about 1-2 times pr. minute! the connection uptime is stuck in a infinite loop: 1.12 sec, 1.13, 1.14 and back to 1.12 sec. It comes back from time to time. but this is the second time this have happened.
I have a D-Link DIR-825.B1, which I've recently updated to the 2.04EU firmware. The update fixed some IPv6 problems I've had, but introduced an IPv4 problem instead: TCP NATs have a rediculesly low timeout of 60 seconds, which makes the router useless for most protocols.How do I set the NAT timeout for TCP connections?
I've not found any topic related to what happened to me. Bought two cameras and upgraded the firmware on both as asked, but one of them just stopped. The light is solid green and not red like other posts.Tried the recovery procedure, but the browser won't find my camera. Changed computer IP and everything else that was told to be done. Nothing works!! I also can't find any posts relaled to my problem all over the internet.
I have just updated myDIR-655 A4 to firmware 1.35NA by the procedure: save config > upload firmware > load config.However after upgrading, my admin page now logout after every ~10 sec of inactivity.I have tried the method where to view the admin page without a style, to be able to set the timeout period, from 5 mins to 3, 8 and 10 mins, but no matter what I set, it still logs me out after ~10 sec.
I am able to access 930L (2 cams) from wifi be it laptop,iphone or ipad but I am not able to see it through 3g.I have Huawei fibre optics broadband reuter from Starhub.Starhub is running away if ask them to fix it. Huawei never takes the call.I tried atleast 3 times 10 minutes each at 8006011450.It goes to disconnect. The lot talked about UPNP is enable in reuter but it does not work.
Now i talked to Dlink support with ticket DCX36811.They advised to load the firmware.I did it still the connection timeout is there. we have baby to monitor through iphone/android 3g.
I'm using the D-link dir-300 wi-fi router. Cable internet connection. PC is connected to the router by the cable and the laptop via wi-fi. Both machines have the same problem - after some time, although there are no package loss when I'm pinging anything, some services report "connection timeout". Such as PvP.net, EA Online and Turbofilm.tv. Soft reset, hard reset didn't solve anything. Although when PC is connected straight to the main internet cable - there are no problems at all. [code]
I have a DIR-825 with 2.60VT firmware (rented from Videotron).
Even though the manual says the stateful firewall should have a timeout on connections of 240 seconds or 7800 seconds, all of my connections start at a mere 120 seconds. I'm having trouble with IMAP IDLE pushing e-mails because the connections timeout so quickly (before any stay alive can be sent). A connection to the e-mail server gets opened on 143 (Videotron) or 993 (encrypted - google, e.g.), and I see the connection on the Internet Sessions page, the timeout starts at 120. When it hits 0, the connection is no longer displayed (it is not renewed), and the IMAP IDLE ****s out because the server can't find the client (i.e. the connection has been closed). But it's not just on those ports or servers. ALL of my TCP sessions begin at a mere 120 seconds! Even for a home router, isn't this way too low?
confirm that their DIR-825, on the Internet Sessions page, shows initial timeout values of greater than 120 for a TCP connection? I would love to see a picture of that screen showing higher values. Does it start at 240? Do you ever see a connection start at a timeout of 7800?
I see no way of changing the timeout value. Is it possible to force connections on certain ports to begin at a higher timeout value?
UPnP renew entry 255.255.255.255 <-> 220.127.116.11:61041 <-> 192.168.0.197:61041 UDP timeout:-1 'Teredo' (this one repeated 13 times just in that 1 info slot)
Blocked outgoing ICMP packet (ICMP type 3) from 192.168.0.197 to 18.104.22.168
Blocked incoming TCP packet from 22.214.171.124:80 to 126.96.36.199:36792 as SYN:ACK received but there is no active connection
this goes on for a multiple of different ip's and i believe its due to the fact that the game i play is p2p
QoS is off spi is off udp and tcp endpoint independent firmware version 1.21 i am using wireless cable isp using motorola sb5101 i believe i port forwarded the ports used for the game but that didnt work so i put my computer into dmz. I've also noticed a lot more jitter then i used to have and my upload speed is down about 4mbps. Was thinking it might just be outdated firmware?
I've been running into an issue for the past week or so where my wireless adapter intermittently can't contact my router.When it occurs the network connection reads as having limited connectivity. I'm unable to send requests to load webpages, and videos and the like stop loading. Sometimes the network disconnects entirely. After this occurs, I can't connect again for a few minutes. My connection consistently reads as having 2-3 bars available. The issue tends to occur frequently, often every 15 minutes or so. Strangely enough, I have been able to play bf3 online for over 40 minutes without connection problems (I quit before any occurred - not sure if any would have). So far I've tried the windows troubleshooter, updating the driver to my wireless networking adapter, manually assigning my network address (tried 192.168.1.4, 192.168.1.5, etc), setting my 802.11b preamble to "Long only" and performing a system restore. I have rebooted my machine as well.
My technical specs are as follows:I'm running Windows 7 Ultimate N 64 bit edition with service pack 1. System has 8gb Ram, an i5-3570k processor and HD7850 graphics card. Motherboard is the Asrock Z77 extreme 4. My wireless network adapter is the TP-link TL-WN722N. The adapter was working fine for some time before this issue appeared.My router is an old U.S. Robotics Wireless MaxG Router. It seems to work fine with other computers in the household, although it does require fairly frequent power-cycling. Running ipconfig on the command prompt while the internet is working returns:
Windows IP Configuration Wireless LAN adapter Wireless Network Connection 2: Connection-specific DNS Suffix . : Link-local IPv6 Address . . . . . : fe80::293a:e9bb:ba5a:7536%14 IPv4 Address. . . . . . . . . . . : 192.168.2.5
For about a month or two now, I've not been able to connect to my router's admin page @ 192.168.1.1 I am using a D-Link DSL-2680 router.
Whenever I go to connect to 192.168.1.1 in my Web Browser, it just sits there trying to connect and does nothing. But eventually after some minutes I get the error: 'This web page is not available The web page at http://192.168.1.1/ might be temporarily down or it may have moved permanently to a new web address. Error 101 (net::ERR_CONNECTION_RESET): Unknown error.' Here is a screenshot:
I tried pressing the reset button on the back of my router, but it would just sit there with the green power LED and another green LED just flashing constantly (I assume this is the ethernet 1 cable LED) and this happens for more than 10 minutes.
All I want to do is just port forward my game servers again without the use of Hamachi or other programs
Region : UnitedKingdom Model : TD-W8968 Hardware Version : V1 Firmware Version : latest ISP : french orange
I am trying to set up port forwarding on this router but it seems I need to use virtual servers but in all the guides there is a menu for this under the advance settings nat menu.I do not have that option, I have downloaded the latest firmware but still nothing.
Built in wifi causing blue screen of death. Disabled built in wifi and purchased USB N150 adaptor and blue screen of death has stopped. Download speed are 75% back to normal but surfing is extremely slow using chrome, IE, safari. Ethernet browsing is normal with no bugs or bluescreen.
I am in charge of taking care our small office network (about 25 PC's) and encountered a problem the other day. I got a call that nothing network related was working. I went to look at the switches/router and everything appeared fine. After some troubleshooting i found if i unplugged the switch and connected directly the the router everything worked prefect. Reconnected the switch, network goes down again. I assumed it was the switch at first but then did a walk around and a laptop was in a weird frozen state. I unhooked the network cable and everything started working away like it should.
Loaned old laptop when hard-drive went out of my own. I knew it would need some maintenance ie defrags, cleanups, updates etc. and have been trying to do so... in the process I am having a very difficult time as all of my browsers (that I thought were updated) are slow, hanging, crashing and causing my entire pc to freeze or hang.
We are working on taking a port off of a switch and connecting it to a mux (TAC 900). Port is trunked to another switch in another geographic location. From wht I am being told from the engineer who handles the transmission end of things he said once our segment is physically connected the mux will crash. He supplied the error code to the vendor and they said it is crashing because of a jumbo packet in excess of 1536 bytes. Soon it will be a moot point as the hardware will be, upgraded but we need tis running NOW.
I have two 7204VXR with NPE-G2 and 1Gb of ram. One router has 2 eBGP peers and the other has 3. The routers receive all internet routes from the 5 peers and send 2 internal routes. There is an iBGP peering between both routers. On all peers I have a route-map to send only our routes.
All was working fine since a couple of months when I suddenly saw an increase of memory on one of the router (router B), 1 hour later the memory was 100% and router crash and reboot. The other router (router A) with the same hardware capacity, same ram and same amount of routes was working good. After router B restart, I shut all eBGP peering on it, keeping only iBGP with router A, ram used was the same as router A (about 50% used) but CPU was about 30% used by process Router BGP whereas router A which has active traffic and active eBGP is only 20% and bgp process i almost 0%. Restarting peers one by one on router B cause the same issue, increase of memory then crash, even with only one peer.
What I suspected :
- A peer on router B but I can't isolate one because the problem appears with each taken one by one
- Not enough memory, but router A has the same number of routes and don't have any problem
- IOS version ? same on both 12.4.(15)T1
- Why process router BGP use 30% on router B when all eBGP peers are shut except iBGP and no traffic pass.
- A routing loop but I only send internal routes to peers and only have one iBGP session with no sync nor redistribution with an IGP
Of course I can't run any debu ip bgp on routers as the number of routes is very large (300K).
I am dealing with three office networks, all three have the same conflict. The error messages I get all say there are two devices assigning ip addresses. As soon as I get the computers communicating with each other, two seem to crash overnight, I suspect due to the conflict. Here is the rundown on the networks. All are windows networks - the problem I am having is file sharing mostly and printing.
Network A: server OS is XP Pro - SP3, four workstations, XP Pro-SP3, Windstream DSL and Netgear Router. I have already bridged the router on this one, and it did not correct the conflict.
Network B: Server OS - Windows7 SP1, three workstations all XP Pro SP3, ISP is Clear (formerly clearwire). Router is the old wired Linksys befsr41 v4.
Network C: server OS - XP Pro SP2, ISP - Clear, three workstations - two are XP ProSP3 one is XP Pro SP2. I have had less trouble with this network, but I suspect the conflict exists here as well.
I have tried to get a static IP address from Windstream where I have had my worst problems, but cannot seem to get one. I suspect we have the least expensive service option possible, and are possibly using a service designed for home use as opposed to business, as someone told me recently that getting a static IP address can be expensive. Is this true? Currently all networks have DHCP enabled, and the routers are set up to use DHCP. My thoughts were to disable DHCP and assign ip addresses manually.
About a week ago, our network started to experience complete failure.
Router: Netgear FVS336.xxx Switch: Dlink DES-1024D (we have 6 of these switches in our building) Wifi Routers: Dlink DIR-601, Linksys wrt54g, wrt54gv2 Computersservers: 40x Copiersfax: 5x Wireless clients: (iphones, laptops) at least 30
All has been working together in harmony for many years.Fast forward to last week when my hell began with intermittent crashes.Not sure what's causing the problem.When it happens, everybody loses their internet, the ability to communicate over the network; ping tests won't respond to anything (including the router) that exists on the lan, even with a static IP against other statics.In visually inspection of the switches and router, they seem to be happily blinking away with no apparent issue (visually).The only way I've been able to fix the problem is by power cycling the router.About 1 second after doing that, we're back in action for 2-6 hours (very unpredictable).I never had to power cycle any other devices)
Steps I've taken in troubleshootingeliminating potential culprits:
Replaced the router with a spare (new) FVS318G
Replaced the power supply for the router (suspected because problem remained after router swap)
Replaced cable going from router to lan switch
Removed linksys wifi router from network (the router had needed power cycling weekly and was old. So I unplugged it)
Removed Dlink wifi router from network (I hate dlink routers, so removed it).I'm at a loss.
i upgraded my computer from win 7 ultimate 32 bit to 64 and when i shut down my computer and power up the local area connecion dont recognize the ethernet card my ethernet card is 82578 dc gigabit not onboard card and i installed all the drivers to the ethernet card could it be my motherboard ? dp55wb?
I just recently had my hard drive replaced by the manufacturer of my computer (Lenovo) because it started clicking. When I got it back it started making my wireless router/DSL modem reset all the time. I didn't have this issue before. I'm running Windows 7 Home 64 Bit. While the computer was off being repaired I was using a Win XP machine and had it connected through Ethernet cable. I did not have any issues with the router/modem while the XP machine was connected. I tried connecting the Win 7 computer up through ethernet cable (hard wired) and it still crashes the router/modem. I also connected the XP machine back up (hard wired) to the router and had no problems. Is it possible that the wrong drivers were installed by the lenovo techs? I have also noticed that my touchpad does not work the same as it did before too. And is it possible that my laptop is making the router crash out due to wrong configurations?
Just updated the fw to 188.8.131.52 and after a while, the device crashed wth the following message in the flash log.
