Cisco :: Lost Access After DNS Change
Oct 30, 2012
Just implemented a couple of replacement DNS servers so decided to test by disabling existing Server DNS services only (10.0.0.21)Two problems arose from this, first was I lost access via the ASDM, second was remote access failed. The Cisco VPN client worked but RDP could not find the remote access Server.I've replaced the DNS settings everywhere I could think on on the ASA so decided to check the running config and noted these lines that refer to old DNS.Would this suggest the cause for the RDP, although looking at the various group policy areas on the ASA I could not locate any reference to 10.0.0.21/22, am I missing something?

We recently had redundant sup cards installed in 2 of our 4507 units after the upgrade I can no longer change Vlan's with the CNA program.I upgrade to the newest version of CNA but that didnt work.
I can still get Vlan information from my 4503's and 4506's with no problem. I figure it is an issue with CNA selecting the sup card to get it's information from?
We are in the middle of some major user moves and changes so I have had 2 of my guys working to move printers on to their own Vlan and some other changes neither is well versed in command line so I set them up with CNA for simple Vlan changes. Now with this out I have to go in and make the changes myself and keeping up with that and my other duties is getting tough.

i bought a WRT160N router
I connected the Router to the modem, and all the wired connected PCs were working perfectly.But then, i went to the setup page to configure the Wireless settings, and as soon I changed the SSID name, the connection internet connection droppedThe only way i had to fix this was by making a Hard Reset.after that, I also tryed changing values and settings from all the configuration tabs, and the wired connection was working properly, but as soon i changed any value from the Wireless tab, the internet connection dropped (even, in the diagnostics section, i could not do a ping to google. It says unknown host).

Today we lost access to our external hard drive (T:). We got the error "An error occured while reconnection T: to \192.168.1.254share Microsoft Windows Network. The local device name is already in use. This connection has not been restored"
Do I have to Re-Map that Network Drive?

A week ago this laptop was working fine. However, now it will not connect via wireless to the internet. It says that it connects to the router but not the internet. I can connect to the internet if I use the wired LAN connection. I tried a restore to two weeks ago (when it was working) and it did not solve the problem. I do see in the wireless network connection status that IPv4 connectivity = local and IPv6 connectivity = local. While on another laptop (that is working and connects to the same wireless router) the IPv4 = internet and IPv6 = no network access. I think this may be the issue, but am unable to find out how to change them.
OS = MS Vista Home SP2.

I can no longer open a http or https connection to the AP. I do have ssh access and I can log in with full privileges.
I was using the Web interface a few days ago and it did something strange during an update. The display of the web page became corrupted and no longer responded to my input.
I restarted it from an ssh session and I have also power cycled it via the power injector. Neither method has worked.
What should I do next or what additional info can I provide from an ssh shell?
Physical access is very difficult. It requires a 30' ladder after 10 p.m. So, I would like to avoid that if possible.

To put it simply, my parents live far enough in the middle of nowhere that they have no access to high speed internet. Of course, there are always wireless solutions, but the options around here are pathetic and comparable to dialup. They were content with this; I moved back in with them for the time being and am not.y solution has been to dump just shy of $1,000 into a point-to-point wireless bridge setup that claims to have a range of 5 miles non-line-of-sight. I have one antenna set up four miles away on top of a building that has high speed internet.Unfortunately, I was a stupid fool and set that end up without enabling security, thinking that it wasn't a big deal. Nobody in that town has a mind for anything but farming and drinking. That was my mistake. Some asshole set a password and forced me to do a factory reset on the access point and now I can find no IP address. It's like it only reset halfway to factory defaults or something

My mother's computer periodically loses internet connectivity. This happens regardless of the browser (IE or Firefox). She must restart her computer to get access again. This happens regardless of her internet connection. She uses verizon at her home and accesses through my wireless router when visiting. This also happens if she is on a public access network such as a hospital

I bought a WRT54GP2 independently of my ISP/VOIP provider so I could have an all-in-one router. As my provider would not provision the VOIP side I disabled provisioning and set up the voice settings myself and it works perfectly.I was reviewing the VOICE settings side and under the SYSTEM tab there were settings for Administrator Password and User Password. Researching on the Net it seems these should be set to strong passwords which I did but then found trouble moving from the main part of the router configuration to the VOICE tab as I would get a message about a non-admin account not being able to administer the voice side. Via clearing the cache on my browser and restarting the router/browser I managed to get back into the VOICE config tab and immediately removed those two passwords. Seeing the settings under the SYSTEM tab it looked to me that the router was open on the WAN side on port 1880 so I disabled the web server and web server admin options thinking these were only related to the WAN side not the LAN side.
I now find out that I can no longer access the VOICE tab as the router immediately disconnects from the browser.I've tried contacting my ISP/VOIP provider but they seem to be unable to assist and have had no luck with Linksys support either as all they want to do is pass it back to my ISP/VOIP provider saying they are the one to reconfigure it but I'm the person who did the config (and also shot myself in the foot incidentally). If I could only reset the voice side of the router back to factory defaults I would be fine but, unlike the WAG310G, there is no option to do this, just the option to reset the WAN/LAN/Wireless side to factory defaults. I've tried pressing the reset button for 30s and reset via the menu option but neither reset the voice side. Surely there must be some way to do this even if it involves opening the box up and connecting a jumper or something.

Over the past few days I've been having a problem with my internet connection.
I connect to my home wifi network and will have excellent signal strength, but after about 20 minutes or so, I will lose internet access, but will stay connected to my wifi network. If I join my neighbor's wifi network I will have the same issue.I will connect to a network, and while still connected, I will suddenly lose internet access (signal strength will remain the same). Switching networks doesn't correct the problem.
When I lose internet, I can disconnect from the network and reconnect mere seconds later and will have the internet access back again.I have reset the modem/router and my computer numerous times but the problem does not go away.

I have a BEFSR41 V2 working as dial in ADSL connection.While I changed my settings of the UPnP in the router I lost access to the admin page. Well most strange is that everything is working.I kept my internet access as well as the computer and printer access.The only thing I lost is access to the router admin page.The password it was not defaulted to admin, neither kept the password that I had set up.

I've switched internet provider from Verizon DSL to Comcast cable just a month ago. Since that time my wife can no longer connect to her work email? I've call comcast many times since the only thing that changed was provider? This is the error I get now
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
I've tried explorer and taken down the firewalls, I had her school IT person remote access to my computer to see if it is on their end...still she can't connect. We can access from other computers (my work) but still not on my home computer (windows vista) Comcast now tells me not there problem since I can connect to internet? I've also changed my norton protect to AVG to see if that was an issue..

I recently bough for a home lab a sg300-10 switch. I have enabled layer 3 routing on it and have come across a puzzling issue. The switch is the default gw on this network, and in front of the switch there is a cable modem (ip route 0.0.0.0 0.0.0.0 192.168.0.7).
This is my config:
config-file-header
switch5ed948
v1.2.7.76 / R750_NIK_1_2_584_002

We've got a SG200-18 switch that is to be used as a workgroup switch in our environment (SW Version 1.1.1.8). Working with CLI on big and mid-range Cisco-gear over the past two decades I'm having a hard time figuring out the following on the SG200:
o) I want to change the Management-VLAN from the default "1" to the management-VLAN used in our environment. Sure enough I created that vlan in the SG200-config, however when it comes to assigning the management-IP and VLAN for the management interface in the corresponding pulldown under "IPv4 interface -> Management VLAN" the only thing selectable is the default "1". (see screenshots enclosed)So how do I set a management VLAN different from 1?
o) How do I enable telnet/ssh-access to the SG200-18 - I'd be far more comfortable with a CLI-environment?

I have an ASA 5520 new. I am trying to migrate from a PIX 515E. I can connect via the CLI and ASDM on the management port (IP 192.168.1.1 the default) What I am having an issue with though is when I change the management port to 10.0.1.1 via the CLI or ASDM I can no longer use ASDM. I issue the show IP command in the CLI and I see that the IP has indeed changed but I still can not get into it. I must be missing something really simple, but this is driving me insane. I want to change the IP because I need the a different interface to be 192.168.1.1.

I am trying to change wpa2 key on an Aironet 1231g access point. Once I change they key, clients cannot authenticate to the access point unless they either change the password or forget and re add the network on the client device. Is there any way to make the client ask for a new key if the key doesn't match when authenticating?

Just installed Linksys E2500 router connected to my Desktop and Cable Modem and access the internet fine. My kindle accesses it and the internet fine. My laptop running Vista connects nicely but only has local access. I find the network and connection area where it sees a network with local only access. I have no clue how to go about changing that. I have the correct password because my Kindle asked me. My laptop does not ask for the password.
