I have Cisco 2821 router, using it to learn various features. I just recieved this router recently. I wanted to connect it to my cable modem so I can access the outside world. Also when I overload a new interface comes up NVI0, which is nat vertual interface, but anyways.
View 1 RepliesWe have multiple cisco routers and most of them have dual WAN connections thru different ISPs. So, we use IP SLA monitor with tracking object s to monitor each ISP availability/reliability and switch routing accordingly ( by IOS). So far, it has been working ok. However, recently, we had some ISP high latency and the connection to one ISP will be so slow but the IOS keep seeing it as UP, thus sending traffic thru it. So, I tried to change around the threshold numbers around with no luck. Is there any configuration/commands or tricks that can do the job here? I don't want the users to be the one to detect the Internet slowness and have me manually shut down an interface or change the static routes metrics. here is a sample of my config:
ip sla 1 type echo protocol ipIcmpEcho x.x.x.x isp 1 gateway threshold 3 frequency 5ip sla monitor schedule 1 life forever start-time now
ip sla 2 type echo protocol ipIcmpEcho x.x.x.x isp 2 gateway threshold 3 frequency 5ip sla monitor schedule 2 life forever start-time now

I have a home wi-fi network that connects through a router/modem to the Internet. There are three up-to-date Windows Vista (Home edition, I think) laptops on the network all of which connect wirelessly to the router/modem. The network is password protected (for security purposes I turn off network discovery. And I don't use file sharing between the laptops). In other words, I have three laptops connected to a common wireless Internet connection (the router/modem). I also have a desktop computer (that I use for projects and gaming), but I don't have a wireless network adapter nor a long enough ethernet cable to connect to the router. I don't have any technical problems connecting to the Internet using a crossover ethernet cable. It's just impractical as I have to dismantle the whole desktop computer system (printer, monitor, scanner, etc etc) and carry it to a different room within cable distance of the router every time I need to update the software or activate a new application.

Would the above router be a good choise for a home office setup for use with WAN speeds upto 30Mbps and VOIP? Any other.
View 1 Replies View RelatedI recently configured a linksys range extender to my modem and since doing that, I'm getting a message stating that there is an IP address conflict with another system on the network. When I set up the range extender, I assigned an IP address to it that was different from the modem but yet this message still appears. Also even though my wireless connection is connected, I'm unable to connect to the internet - I keep getting the message 'internet explorer cannot display webpage'.

View 16 Replies View RelatedI have been having problems forever connecting to internet at my apartment. My roommate has a Belkin router, and him and my other roommate have no problems connecting. I used to be able to get on it fine, however now I either get "connection unsuccessful" or "unidentified...(Belkin.3BC3) - Limited Connectivity" when I try to connect. Our landlord provides the internet, and we have the base router(not wireless) in our basement. But even when plugging into the wall with a ethernet chord I get local only. This is the only place I have any internet problems, anywhere else I can connect just fine.

For a little background, my son installed a router for a couple of months and when he disconnected his computer I lost connectivity with my desktop. The router is gone, I am directly connected to the modem. Seems like the ip address reverts back to the address that the router assigned for 30 seconds then to 169. ........ I have tried all sorts of fixes that I have found on the net, but none have worked. Have changed modems, ethernet cables, ISP has also tried but nothing has worked.
View 19 Replies View RelatedAfter recently having a new BT home hub 3.0 installed in our house my computer is unable to connect to the internet. Everything else connects laptops, PlayStation, iPod's just this one computer doesn't.
When the computer is turned on the wireless connection manager says that it is connected and then very quickly loses it again. After reconnecting the computer and trying to go on the internet, explorer says that it is not connected and i can not go to any websites.
Leaving the computer running, the wireless network establishes a link, with full signal strength and then loses it again just as quick. This will just continue for as long as the computer is on.
Computers is not a strength of mine but when trying to repair the connection the computer stops at 'renewing IP address' and does nothing. The only other message i have seen is- 'status: acquiring network address' this never completes and the link is quickly lost.
I have Wi-Fi in my house and we able to connect my mom's laptop, her smart phone, and my iPod touch to it, but I just got a used PC from my grandfather and have no clue how to get internet on it.My family already has a PC with a DSL modem and wireless gateway connected to it. We do not have a "router" and the only phone jack in the house has the DSL modem connected to it.From my understanding, the easiest fix is to make my "new" PC Wi-Fi capable, but how do I do it? It is running Windows XP.

View 2 Replies View RelatedI am having difficulty getting my HP Officejet Pro 8500(A910) configured to save digital faxes to my Iomega 2TB Home Media Sever (cloud edition). My home network is setup through a Linksys E4200.I was able to successfully configure it to save to a folder on my PC, but I do not want to leave it running 24/7.I believe the breakdown is in the Authentication part of the setup... It asks for the Windows username and password, which works fine for the PC setup but not for anywhere else. Do I use the UN & PW for the home media server if I'm saving to one of its folders? If so, how do I correctly type the path? It is communicating with the folder and leaving an alphanumeric file saved inside the folder when I use the 'save and test' option, but it breaks down from there.

I can't get it to connect to my home wifi--it just says "Can't connect to this network" and nothing else. I did unplug and plug back in the router (does that count as resetting?) and it didn't change anything. I just went to the library and it connected to that wifi without a problem. While there I uninstalled all Norton security products and installed AVG Free 2013. Still not working.

We had 2 laptops and a pc working through a router with no internet problems. My wife's Toshiba laptop had other problems so IT guy at the college where I teach did a clean install of XP and checked the machine in his office, including internet. No problem. Brought machine home and no internet connection. My laptop works fine on wife's cable to the router. Wife's Toshiba has wireless but cannot establish connection with wire.Another tech guy who lives above us took the laptop up to his place - no connection. Back in the office (different building)- connection. The IT men are baffled. Me too.

View 2 Replies View RelatedI'd like to use 2 internet connections at the same time.Assuming there are two internet networks.Network A and Network B (both are either wireless OR one is wireless and one is wired OR both are wireless).So, now I want to use BOTH internet connections simultaneously. However, both connections will still be separate and not combined:If I had to transfer big files, then I could do this on network A.Now, I want to use network B for other "normal" internet use so that the transfer of files in network A gets the maximum speed since there is no interference with anything else.I have to let the computer know somehow that there are two connections used simultaneously. I also have to setup what programs use what connection. E.g., IE uses network a and Firefox uses network b, program "x" also uses network b, etc.I would use two network card/USB Wifi Adapers so that each network card/wifi adapter can connect to one network.
View 7 Replies View RelatedI'm having trouble connecting my 02 dongle to the internet using my router. My router is a TP-LINK MR3420 and my 02 modem device is E1752. I checked to see if the modem is compatible and it says it is. I went through the configuration that was given to me with the router and I tried using you tube but nothing. Do i need to get a static I.P address off my Internet provider? If I plug my 02 usb dongle directly into my computer it works perfectly and I got the router to work using a ethernet cable and plugging it into the WAN port at the back of the router but I would prefer to let it connect through the 3g port. I get a connection at 40% and 100 bytes are sent and some are received but the connection drops. Is it a problem with the connection? I will upload a image.

I am sitting on Internet and want to copy IOS Image to router. I can SCP, itu authenticated to Router but ends with a message "host is not communicating for more than 15 seconds".
Router : Cisco 2821
Current IOS: (C2800NM-ADVENTERPRISEK9-M), Version 12.4(24)T1.
We have 6 brnaches configured with NAC Module in Cisco 2821 ISR router. The WAN link being used to connect all the branch to the HQ CAM is via WIMEX wireless Broadband. The bandwidth is 2MB.OOBVG is the mode used. All branches were working well last 1 year. Last month it is suddently disconnected from the CAM.I opened the TAC. Cisco history of TAC experience, We have total 6 TAC enginners tried one by one still the problem not resolved. The following are the findings
1. Timing is accurate between CAS-CAM
2. Shared secret key correct
3. SSL temp certificate ok also image being used it 4.6.1.
4.Tcpdump from both CAM and shows some initial packet drops of 10 sec with the below CAM log
I believe that NAC is not a matured products and the problem like this even by Cisco TAC can not solve.
I am looking for a simple router recomendation for multihoming dual 100Mbps internet connections with BGP routing. What are the current best practices regarding required resources for the full Internet BGP routing table? We were thinking of specing a 3945 for this application, but is that overkill? The customer has a 2821 that is not in use, I'm thinking this would be too slow for Internet BGP routing combined with the 100Mbps line speed.

I have an IPSec VPN and NAT configured. Return traffic from an internal NAT host seems to be blocked by the WAN inbound ACL. What is the proper way to allow return traffic from the Internet for this internat NAT host? Note: As a test, removing the deny entry on the WAN ACL allows return traffic.

My Wifi network has a wpa2 password that is a random string of characters and numbers and yet last month a rogue IP Address kept popping up on my DNS list. It has to be coming from my neighbor who's bedroom is about 15 feet away from my router. So unless someone is sitting out on my front lawn to do this then it must be him.I've been looking for software that will notify me when a connection my router is attempted and kudos if it also asks my permission first would be great.There are wifi packet sniffers out there like Cain&Abel, Airsnort, that sort of thing but I am not quite savvy enough nor do I want to turn this into a complicated hobby but just need a basic warningin case something gets past my passwords again
