Cisco WAN :: 851 Routers Are Frozen Almost Once Or Twice A Day
Jun 28, 2011
We have one cisco 871 and five cisco 851 routers , all those routers are connected to each other using site to site VPN tunnels, so each router have 5 tunnels, we are usong thhese routers for IP phones, each location have 2-3 IP phones and 2-3 computers, all routers are connected to internet using ADSL modems,
out of these 6 locations 2 cisco 851 routers are getting frozen once or twice a day, and we need to reboot them, I already changed the router at one location with new one but problem is still there, but if i look for the logging ( Show logging ) its shows only interface up and down status that because of reboot, i cant find what is the reason these cisco 851 routers have 4 port LAN swithc in built, that still works even router is frozen, i was not able to ping or access the router not even using console.
laptop has frozen on "this programme cannot display the webpage". cannot access start menu, task manager or anything else. Can turn off with power button but when it comes back on it flashes on the desktop then reverts immediately to the "this programme ........." page again.
Recently we ha a Nexus 7010 with a module frozen that was OIR (Online Remote and Insert) but do not work until reload the Nexus 7k.The command "show tech-support" has the following:
My Cisco 871w still stops working once a week.Today I found it frozen, after the weekend, and I have executed few commands from the HyperTerminal .The commands were given by cisco coleagues in previous post :show logshow ip int briefshow interfaces counters errorsshow interface FastEthernet1show interface FastEthernet1 statshow interface FastEthernet1 summaryshow interface FastEthernet1 switching
All my gmail accounts open normally to the first page, but the mouse cursor just highlights whatever I hit. It will not open to the relevant messages or any other action.The sign out function works, so I can go to my other accounts, but the same problem persists.It had been working fine for several years.All the accounts are fully functional when I use my ipod or go to another desktop.
I have had this wireless router a year or two and it had been working fine until late last night when it just quit. It will not connect to any wireless devices in the house. When my main PC is connected to the router, I cannot get on the internet at all. If I plug my PC directly into my DSL modem the internet works fine. I tried the reset button on the router and still nothing. When the router is connected I get this message:"Limited or no connectivity. You might not be able to access the internet or some network resources. This problem occured because the network did not assign a network address to the computer"It's very hard to troubleshoot the problem on the internet because if I have to connect the router to try something then I lose my internet connection.I hate when things quit working spontaneously. Absolutely nothing changed when this issue started. One minute it was working fine and the next it wasn't.
Ciso 1941 router frozen once a day, sometimes after 2 to 7 days. When the router frozen, no internet connection and cannot login/ping ethernet ports. I can login to console port and copy the error messages below. Reload the router and it will return back to normal operation. Re-installed IOS but still the same.
IOS Version 15.1(2)T2, Cisco CISCO1941/K9 (revision 1.0) with 487424K/36864K bytes of memory. DRAM configuration is 64 bits wide with parity disabled. 255K bytes of non-volatile configuration memory. 250880K bytes of ATA System CompactFlash 0 (Read/Write)
I have 2 internet connections in my office one via Verizon Fios and another one via the local cable company. On the fios connection I have an RV042 VPN router and on the Cable company connection I have an rvs4000 router, I would like to know if there is a way I can connect the 2 so I can share a printer I have on one of the 2 networks from the other network without using the VPN feature, like via an ethernet cable connected between the 2 and some kind of static route maybe?
I have RV042 and E4200 routers . I tried the manual UPnP port forwarding using Rv042 router and was succesful ( by typing 192.168.1.1 in the explorer and logged in using user name and password )
I am using a linux embedded system whose Internal IP ,Internal port are mapped .This system is connected to one of the LAN ports
I want to try auto UPnP port forwarding both for RV042 router and Linksys E4200 routers
After enabling the Upnp option only and logging out ,Can i add a port mapping entry in this router without logging in using a C++ program which runs on linux embedded system .
I was looking for a small business router that has VPN support and dual WAN support for load balancing. Upon reading reviews, I think RV042/RV042G is a good choice. Now am thinking if it supports intervlan/ router-on-a-stick configuration?
If your wireless indicator is flashing red when you discover the smurf, it can mean that someone has tried to logon with an incorrect password. this is not necessarily an attack, it could be someone you have allowed access too, who has forgotten the password? In this case entering the correct password will solve the problem.However putting your own MAC address into the filter will simply block your own machine.
For my work I am looking to create wireless capabilities to remote locations. To do this we are using a standard modem/router that is connected to an Engenius (802.11b/g) wireless outdoor radio connected to a dish antenna. We are able to go to locations (3+km) and then with a corresponding receiving antenna (using LoS), receive the Internet and connect both to computers at the transmitting point as well as to the WWW. The problem exists is that we want to employ a series of routers at the receiving end that would be able to carry the transmission to a different location (relatively close), due to the fact that some of the locations do not have line of sight to the antennas. We are using Encore routers, model # ENHWI-N3. When we connect the radio's Ethernet into the routers WAN reciever, we can connect to the Internet with a computer. The problem exists is we want to pass that connection over to a second router (R2). This connection is done when the routers are on access points set to a WDS function with R1 having R2's mac address and vice versa. Both routers are set to channel 1. Even when the routers are seperated by distances >50m a computer plugged into R2 can see a computer plugged into R1. Files can be transferred between the 2 computers wirelessly at speed around 3 mbps. However computer 2 on R2 can not connect to the WWW. This router features a spot that lights up if it has Internet access and R1's is lit up but R2's is not. How do we transfer the Internet and not just a LAN from R1 to R2 so it can be accessed further away from the point of the radio and antenna equipment. This setup has also been used where R2 is hardwired to R3. At R3 we change the channel to 11, and then connect through that with mac addresses wirelessly to 4th router. If comp is in R4 and far away it can still access and file share from comp at R1.*edit the ip address for the routers exist all on 192.168.1.xxx If the 3rd number is different between routers would this make a difference?
everything was all good, my brother went crazy and unplugged everything.it effects our house phone too, that could be the problem.i just dont know what wires went where. all the wires are the same color.but i know which is which. just again, dont know where.i would like to get it done before he gets home later on.
We're getting the following message in the logs when we ry to connect: encrypted Informational Exchange message is invalid because it is for incomplete ISAKMP SA
One of the router is a V2 and the other is a V4 if that makes any difference.
The first router is wired to the DSL modem and works just fine as an access point with Internet access. The second router is wired from the first router using one of the 4 ports on both router hubs. The second router is visible but has no Internet. How to configure the second router regarding DHCP, LAN, WAN, DNS etc.
......................Computer 3 Router 1 points to a VPNRouter 2 access to the internetComputer 3 needs to access router 1 (VPN). Both Computer 2 and 3 are in a different room than computer 1, and router 1. Computer 2 is networked via cat5e to router 2.Is is possible to have Computer 2 and 3 share the cat5e, yet access different routers?
What Happens if I Used 2 to 4 more wireless routers acting as Main Routers in my network? that their DHCP are enabled? would it cause connection Disturbance? I Have 4 Cisco Linksys E300 all of thier DHCP are enabled..so they have 192.168.2.1,192. 168. 3.1, 192.168.4.1, 192.168.5.1
I have the N600DB Wireless Router I am connected to the internet, but cannot open My Routers Homepage with http://router or http://192.168.2.1. How can I get to this page to reset the router settings? I also cannot connect any of my wireless devices to the network..
I have two matching N300 Belkin routers. The cable modem feeds into modem1 and modem1 feeds into modem2. I get a good wireless connection on modem1. Modem2 shows up on a wireless scan and it accepts the password. It however will not connect.
How to set up a home network with 2 routers, where R1 acts as the DHCP server and R2 is basically a switch, connected LAN to LAN and everything is on the same subnet. Currently I have a different setup:Both routers have the DHCP server enabled and I connect R2's WAN port to R1 LAN. Therefore I have 2 subnets. Now my special requirement is that R2 is a DD-WRT router, which establishes a VPN connection to StrongVPN, so that all internet traffic via R2 is encrypted and goes through the StrongVPN server. Now my question:If I change my router setup to the same subnet, meaning R2 connects LAN to R1 LAN and I disable DHCP server on R2, will R2 still be able to establish the VPN connection?
i want to ask if i can link two routers while they are totally separated of each other over the internet to make a large LAN the two routers are TP link?
How do i connect two internet routers to one IP address range?I currently have one broadband router connected on 172.16.0.3 subnet 255.255.0.0, I have a second line which is a copper ethernet EFM 2Mb line connected using a Cisco 1800 router configured on 172.16.0.254 subnet 255.255.255.0, no DHCP is configured on either router. the dhcp is provided by a windows 2003 server on our LAN which is also configured on the same LAN IP range. if i connect the Cisco router into the same switch as the broadband router my network devices stop working and dont respond.
If i check the broadband router it shows all the connections to it as having the same MAC address as the Cisco router?? if i disconnect the Cisco router everything returns back to normal and works perfectly.What I want to achieve is to be able to run both routers on the same LAN to provide internet access by configuring the pc's to route through a specific router. the DHCP I want to stay routed through my original broadband line. at the same time i want all pc's to access to the lan devices (ie. servers and printers) what the correct configuration would be for the two internet routers would be?
I have one cisco 2851 router and one watchguare firewal currently being used as the main router. I want to connect the cisco as a secondary router on the same network.
In my office we have concrete walls and very limited wiring. The way it is set up is we have a Verizon DSL Modem that comes in then I have a router with it that splits the signal to 4 other routers that each split the signal 2 to 3 more times. I have to use routers so that it assigns IP addresses.I bought a new D-Line N300 Wireless router with USB imput. I want to attach my Home Media Network Hard Drive Cloud edition to the 1st router (attached to the modem) and then share the data off that hard drive with everyone connected to the sub routers.
I am trying to connect 2 wireless routers to expand my wireless signal. I want to connect the router 1 (in 2d floor) to a powerline av and then get the router 2 to the powerline (in the ground floor) so i can have wireless there too. I've tried some configurations i found online, but can't get to make the network functioning. The routers and powerline av are all dlink. I don't mind having 2 networks, but it would be better to have only one
I have a laptop connected to a net gear wireless router (for internet), but I am very close to buying a Belkin network USB hub to make my hard drive wireless, but this requires a router. I do not want move my hard drive to where my net gear router is, so I need to get another router, i am looking at a Belkin router so that I can make my hard drive wireless (This is the only reason for the router, it will not be used for internet) so I can keep my hard drive in the same place.
I would like to hook up 2 ip cameras to a server. I need to use 2 routers to do this. I already have the routers. router a is hooked up to the server. router b needs to connect wirelessly to router a. I can then hook up the ip cameras to router b. I just can seem to get it figured out.
