I have cisco 2600 router. The problem is my router ios has been crashed and i unable to use any mode on my router. I need to install new ios. How can i install or upgrade new ios step by step.
View 1 RepliesI upgrade to a Flash 32mbs memory stick, as I reboot the 2600 Cisco router, it appear in the ROMMON mode, nonetheless, I followed some wrong procedure by changing components on the ROMMON command line. however now the router reboot or start with symbol only V2V2v2a, and I can no longer enter the ROMMON Mode or key anything in. I have a copy of the IOS on my TFTP server.

I have to set up the AP in a standalone mode to support voice and data traffic through the wireless network. for this, i was trying to look for the config guide so i know how to go about it, but all the doc was refering to controller based setup. i followed this link URL
I have never worked on wireless in a standalone mode, so this is the first time i will be doing it.
I am not able to connect to any webpages in normal mode, even after restarting i still have the same problem [However it works in safe mode with networking]. The network connections show that it is connected and the signal strength is excellent. I then have to keep restarting the laptop like 3 to 4 times and it works. Its kind of frustrating to keep doing this all the time and besides i am scared by restarting the laptop so many time can harm it.

I have installed a mini router type MR3020.I have set it up to WISP mode in order to get wifi signal from my main router and be able to deliver wifi to other devices The main router is working fine and I can access internet with no problem.However, the mini router, which detects the main router, is unable to supply internet connectivity. The ip addresses in teh WAN part under network is zero. Though I tried many times to renew the ip address I was not able to get a valid IP address.
I'm using Linksys WAG200G Wireless modem and connection mode is "Bridge Mode Only", in this mode I'm not getting the 192.168.1.1 setup console and Wifi facility.

View 2 Replies View RelatedI have a cisco 877 router connected to our adsl broadband at our head office. I have managed to set this up with Nat and DHCP all working to let multiple users access the internet through our single static ip supplied by the ISP lets say the ip is 1.2.3.4.Our internal network is 192.168.1.0 255.255. 255. 0.I have a draytek vigor 2600 at a branch office set up the same with a static ip addresss supplied by the ISP lets say the ip is 5.6.7.8.The internal network is 192.168.4.0 255.255.255.0
I am trying to set up a VPN between the head office and branch office so the branch office users can connect to our internal server(lets say ip is 192.168.1.2) to receive group policies,access files and also telnet into our database server(lets say ip is 192.168.1.3).I have attached a sort of running config that i have pieced together from bits i have read on this site and others. I have tried these settings and other permutations of these settings but i cant seem to establish a tunnel even though when i show int tunnel0 on the router it says tunnel is up and line protocol is up, if i show ip route it shows that there is an ip address for the tunnel and that is about it(No vpn light on).
If it makes sense and that I have entered the right information? I have highlighted the parts i am not sure about in red(Quite a bit and obviously not the exact settings but what i think it should be). Once all the settings are correct on the cisco will it automatically establish the vpn or do i have to dial it from the draytek.
i want to configure the router for internet access for hosts this is the my pub ip x.x.x.174 and mask 255.255.255.252 this is isp given subnetmask internal ip range is x.x.x.20-x.x.x.254

Working with wired Cisco equipment for many years, but trying to configure an integrated wireless AP for the first time.
I have a Cisco 891w router with the following software (main and integrated AP801 wireless AP):
1. Cisco IOS Software, C890 Software (C890-UNIVERSALK9-M), Version 12.4(22)YB
License Level: advipservices
2. Cisco IOS Software, AP801 Software (AP801-RCVK9W8-M), Version 12.4(21a)JA1, RELEASE SOFTWARE (fc1)
Opening a connection to integrated AP801 wireless device for performing wireless configuration tasks, the connection is established OK, authentication is passed OK using credentials from main configuration file, gaining level 15 privileges with enable command, but after that... no way to enter "Global Configuration mode" because there are no "configure" family commands present!!! Simply can't say "Conf t" because there is no such command!

View 20 Replies View RelatedWe have an old Cisco 2600 series router, running a single T-1 line, AT&T is the carrier. Very standard stuff.
The T-1 works perfectly on the old router. Cisco 2600 with a WIC-1DSU-T1 card. We have a brand new 2911 router with a VWIC3-1MFT-T1/E1 card in it. The circuit runs 100% clean and trouble free on the old router. When I plug it into the new router, it shows up/up but has a massive number of errors on the line, and the circuit is not usable. There are no timing slips or anything like that.
I have another site using the same router and card with the same configuration on that T-1 and it works perfectly. Zero errors. This site (in a different city) is totally slammed with errors. We already replaced the T-1 card and still have the exact same issue.
I've actually been doing this a long time, and I've tried all of the usual things, adjusting line build out, changing clock source, checking and re-checking configs. Nothing seems to reduce the error rate.
I personally think it has something to do with the Smartjack. Like maybe their LBO is too high or too low, and the old router card was more/less sensitive than the new one?
This is a layer 1 issue and is not defective hardware or defective configuration. I am looking for T-1 insights or bugs/issues.
I was provided with a new wireless modem from our internet service provider (the old modem was antiquated and needed updating). After this, i have been unable to connect to the internet on my laptop on a wireless basis. I can search for the modem via the usual means and seemingly connect, but when i am connected it states that i have 'Local Access' only and i am unable to access the internet at all. I am also unable to connect to the internet on a wireless basis when in safe mode.I am however, able to connect using a Ethernet cable from the modem.My laptop is fairly old but it is fine for our needs and thus i do not really want to change it unless totally necessary. I just wonder if it is something relatively simple that i am overlooking?My son also has a more modern laptop, and he tells me that he can use the internet via our new modem without any problems. Which would suggest there is nothing wrong with the modem.The operating system is Windows Vista, if that makes any difference.

I am connecting a 2600 router to an ISP. Interface 0/0 is connected to the ISP using DHCP. Interface 0/1 is connected to the inside providing DHCP services to the inside. At least it should only be providing DHCP services to the inside. I also have a public static IP that is NAT to a private static IP. Everything is working except the computer on the static IP. From the router I am able to ping inside and out from each interface. I am able to ping both interfaces of the router from the computer on the static IP but I cannot ping outside the router. If I do a debug all I see a reject for the gateway of the static IP but it has “mobile IP” in the text string. Not sure what mobile IP is relating to. Networks are as follows:
0/0 DHCP 10.X.X.X
0/1 192x.x.x
Static 75.X.X.X
no ip dhcp use vrf connected
ip dhcp excluded-address 192.X.X.1
