Cisco Wireless :: 5508 Internet Both Wired And Wireless / Access To Server Everything Dead
Oct 24, 2011
have a Cisco 5508 controller (version 6.0.199.4) that when I enable global multicast mode it will work for an hour or two and then it will kill the network. All internet both wired and wireless, access to server everything dead. I then have to directly connect to the service port and disable the global multicast mode. Then two reasons for enabling it are Docs2Go and LanSchool both require multicast to be enabled. I have it enabled on our wired network and it works OK there. ted.
I have an RV042 Router and did a one-to-one NAT mapping for my server using an additional external IP I received from byt ISP, pointing to machine 192.168.2.5. I am now successfully able to access the machine via the external IP without issue, however the server is no longer able to ping any external IPs?
the machine has been assigned a static IP of 192.168.2.5 and static DNS servers.
It has happen suddenly : Internet is not working through WRT150N, though it work when directly connected to the modem. So I think it is a router issue :On the WRT150N, Internet light is flashing fast for 2 seconds, then is off for 2 seconds, then flashes, then is off and so on, wether there is a device (computer, modem, ...) plugged or not, through the blue ethernet connector.And sometimes, Internet light stays off from power on, whatever is done with ethernet connexions (yellow or blue).
When connected to the blue ethernet Internet connector, my pc ethernet lights don't blink (nor the link light or the data light)I have try the 30-30-30 reset cycle. But it doesn't improve.I have tried the loopback test : connect an ethernet cable from the one of yellow ethernet port of WRT150N to the blue ethernet of WRT150 N.Sometimes, the light for the yellow ethernet port goes on for a few seconds, while the Internet light continues to flash. After a few seconds, both go off.Sometimes, as soon as the loopback is made, the 2 lights go off, and if a computer is plugged to the yellow port, the ethernet lights of the computer and the router stays off.But I can access to WRT150N through Wifi and I can access to the web management.
I am running a 5508 WLC with 10 Access Point. we need to allow Internet Access to Guest. 10MB DSL Internet is dedicated for Guest. This link is terminated on a regular ADSL modem without being part of our network. We want all Guest Internet traffic to reach the ADSL Router. where should I create the Guest VLAN / where the DHCP for Guest users should be created. what is the best practise for similar setup.
Our Network is simple ISP_Reuter-------ASA_Firewall--------------4505------------LAN-switch 2950
ADSL_modem------------ users connect via wireless but restricted to certain area only.
I have a dell desktop with win xp i need to activate but cant get online to do so. The dsl and internet lights are on and my nic light is on via the ethernet cable.I went into safe mode to do a ipconfig and i got a internal error request not supported message. I wanted to try configuring the network connection settings but when i clicked on that in control panel when i was in safe mode nothing came up.
Last week the Verizon-supplied DSL modem went bad (wasn't receiving data) and was replaced.
Now I can get Internet direct out of modem, and when I connect it to router the router's Internet light is on, but it seems to stop there. Devices connected to router via Ethernet or wifi don't get Internet.
I'm able to get to the router's admin console via Ethernet and wifi, but no Internet.
MY ISP is AT&T. I have their Westell DSL modem, with a bridged connection to a Linksys wireless router. The router is connected via ethernet to a dead computer: a 7 year-old Dell desktop that will boot up but shut down right away. I have been able to connect multiple laptops wirelessly to this network. I thought an ethernet connection was required in a home network such as mine? The cable has been plugged into a dead computer for several months and frankly I'd like to get rid of the desktop. What exactly is the ethernet requirement - just to be plugged into a port? Could I theoretically just yank the ethernet card out of the desktop and use it instead of the whole dead system?
I have 2 WLCs (Cisco 5508) in my network. The primary has 16 Aironet 1261 APs connected. Secondary WLC is just staying there and no APs are associated with it. Everything works fine. I was accessing the controller via a wireless client all this time through the management interface 10.74.15.2 using https. It was working fine.But when I tried to access the primary using the wireled network, I can access the seconday but cannot access the primary. They are in the same subnet and I can ping both of them.
My Dell XPS 8300 has been connecting to the internet without a problem for months until this morning. This morning the computer will not connect either through the LAN or wifi adapter. The network tray icon has the yellow triangle and says "no internet access."
I have reset both the computer and router multiple times and I have also unplugged them in between. Other computers in the house connect to the router without a problem wirelessly. This leads me to believe there is something wrong with the networking/system software configuration. The computer can't ping the router. It may be the software/system config was corrupted in the last 24 hours and I may need to reinstall the operating system which I would rather not do.
It doesn't appear that any unusual software updates were made in the last 24 hours beyond Adobe Acrobat and Flash. There have been no system updates that I could identify within the last month or so.
Is there any way to configure a wired guest network with a combination of 5508 and 2504 wireless controllers? I am aware that the 2504 does not have wired guest functionality, however is it possible to set up a wired guest on the 5508 and using mobility anchors, transmit the l2 information through eoip to communicate with the remote vlan?Home built NAC solution, using 802.1x authentication on switchports for public areas. If user is an employee, communicates with the supplicant on their machine, and places them on an internal vlan.If user is a guest, user fails 802.1x check and is placed on a "guest" vlan with an ACL and external DNS.If placed on the guest vlan, the user has to accept a terms of use form.This is working currently with our 5508s without any issue, however we have some remote offices we'd like to roll this out to that are using 2504 controllers. I'm hoping there's a way that I can use the 5508 as an anchor or vice versa to make this work.
My laptop wont connect to a wired or wireless network in my house. its an acer aspire 5741 series. the other laptop that im using to write this connects to the modem with no problems. all mobiles are connecting fine aswell. is my computer broke?
I have a problem with my Router WRT120N wen I connect to router with wireless are wired it`s not giving me Internet access but the light on the router of Internet is ON if I put the internet cable directed to my computer give me internet.
Is there any way to use the e2500 without having hard wired internet access. I would like to use with my wii fii hot spot so that I could use my old printers that are not wireless enbled
I have 5508 controller in my lab. I am working on a project to set up a public internet but with some condition.
- User should able to connect to the SSID without any authentication.
- Once user will connec to the SSID it should redirect to an external URL which indicates terms and condition and email address field.
- User should enter his/her email address in email addrss filed and click I accept button.
- Once that is done then he/she is allowed to access internet.
We are not sure how can we achive this as I do not know what should be the return value for WLC to allow that user to go through or what should be the settings on the WLC to redirect to the page.
I have seen a settings on web authentication for external URL but I guess it is only for username passwor or Radius authentication. While in this case I do not want to use any authentication just an accept buttor or Decline button and all good to go.
I'm having problem with windows sharing (file/printer sharing) from Wireless lan client which is connected to AP3500 and WLC 5508 then to Nexus 7010. It's already using ip command, for example \192.168.84.65 WLC os version 7.0.116.0 (using AP groups) Nexus os version 4.2(6) The weird thing is i can connect using windows sharing from wired LAN to wireless user however not vice versa. f
-Wireless lan to wired LAN using windows sharing - failed
-Wired LAN to Wireless lan using windows sharing - success.
I've been analyzing by making sure that all the to end, there would be no firewall within source pc(s) and destination pc(s) and also the ACL inside Nexus. Been dying here to find solution for this, due to the customer is using it for file and printer sharing service.
Could I setup wired guest Internet connection without layer 3 web authentication and how?I want guest users access Internet without going through web authentication.
We created a VLAN interface and a WLAN on the wireless controller (5508) and using it for Guest Wireless (Web auth), can we use the same VLAN and WLAN s for Wired Guests also?
I setup a guest wired network on the WLC 5508 with 7.2.110. A postage machine can only be setup for static IP address over guest wired network. Is any one how to get it configure on the WLC 5508?
I have a Windows 7 machine that is a client to an old SBS 2003 server. I don't use the server but once a month anymore because there is some old software that I need to keep on it. I also don't want to use the server for internet access anymore. I just use a wireless adapter on the client machine for internet connection. My problem is that I can either use my wireless adaptor for internet access or connect to my server. I can't do both at the same time (I get the "multiple networks red x") and no internet access.
I have 4 computers (3 laptops, 1 desktop) in a shared office. We get internet access using their wireless network. All works fine. However, I need to share a printer amongst all of the computers. The printer is LAN enabled and I would normally just put all the PCs on a hub, together with the printer and share it that way. BUT my question is can we access the internet using the wireless network and the printer using a separate wired network at the same time?
My router is a Linksys BEFSR81.Recently I installed a proxy server and now I would like to setup my router so that only the proxyserver (HTTP traffic) can connect to the Internet.
I have Internal DHCP Server configured on the Cisco WLC 5508 and all is working fine. DHCP Range is 192.168.1.100 to 192.168.1.245. Now I created another SSID but I want clients connecting to this SSID get specific IP's or from a specific range. WLC has no option to bind a DHCP pool to a specific IP so what I did I checked the option to "Override DHCP" and added the IP of my firewall WLC is connected to and setup a DHCP Pool on that firewall as 192.168.1.89 to 192.168.1.94 (192.168.1.88/29).
Client can connect to the second SSID but can't grab and IP address, what am I missing ?
I am biulding a wireless network with 5508 WLC and trying to use ISE as radius server and also to redirect the web-login to it.I was trying to understand that to achieve the external web-login, do i need to use the raduius-nac option under advanced on the guest wireless where i am trying this out. and if not, where do i actually use it?So far what i have understood that i do need to have preauth ACL on the Layer 3 security, but the issue is there is no hit reaching the ISE.
We just got a new 5508 wireless controller and the question we have is : can we get wireless users to authenticate to an Active Directory server to get access to the network? I know we can get the authentication done with an RSA server, but what about plain AD?
Recently I came across a wireless design whcih I ws not able to understand.The design is:
1. Two wireless LAN Controllers 5508, each with 25 AP license. AP load (5APs per Contorller) shared between the WLCs and congured with Backup Controller option.
2. The design has a Data Center Switch 3560x series, on which the two WLCs, Cisco Prime Infrastructure and Cisco MSE were connected. I've attached the design here.
3. The Data Center Switch is configured with DHCP pool for the wireless clients. The IP Address of the Data Center Switch is : 10.xx.xx.2 and Default Gateway is: 10.xx.xx.1
4. On the WLC, the Management Interface is configured with the IP Address: 10.xx.xx.21 for Controller 1 adnd 10.xx.xx.22 for Controller 2. But, their DHCP Server is configured with IP Address: 10.xx.xx.1 but not with 10.xx.xx.2 .
This means, all the DHCP requests are pointing towards the Gateway of the Data Center Switch.Is this the correct configuration?I have seen the Wireless Clients getting the IPs allocated from the DHCP Pool, even though the Management Interface's DHCP server configured with Gateway IP address 10.xx.xx.1 .
The DHCP configuration for the Data Center Switch is:
ip dhcp pool xxxxxx network 10.164.220.0 255.255.254.0 default-router 10.164.220.1
The Management Interface configuration on the WLC is:
Interface Configuration Interface Name................................... management MAC Address...................................... 2c:54:2d:72:b5:40 IP Address....................................... 10.164.220.21 IP Netmask....................................... 255.255.254.0 IP Gateway....................................... 10.164.220.1 External NAT IP State............................ Disabled
I am hoping to get your feedback around the dhcp issues I am facing with Two Centrally Switched Wireless LANs. The setup is as follows:
- I have a WLC 5508 which has been configured with 4 SSIDs, out of which 2 are using Central Authentication and Switching. - I have an LWAP connected to the WLC in HREAP mode. - WLC is configured as the DHCP server for clients connecting to the SSID 'Guest'. For the rest, I am using external dhcp server. - Only one scope for Guest Interface is setup on the WLC.
Problems: 1. As far as I know, for WLC to act as internal dhcp server, it is mandatory to have the proxy enabled, but the Clients connecting to SSID 'Internet' are unable to get an ip address from the external dhcp server, if dhcp proxy is enabled on the WLC. If i disable the proxy, it all works fine. 2. DHCP does not release the ip addresses assigned to clients even after they are logged out. 3. If a machine which was earlier connected to 'Guest' SSID connects to the 'Internet' SSID, it requests the same ip it was assigned by the WLC which it was assigned under 'Guest', but gets tagged with the V LAN configured on the management interface.

A client wants us to use the internal DHCP server on a 5508 instead of Windows DHCP. They will have 15 APs initially and upto 25 later. The docs on the 7.2 WLC make it sound like this is discouraged: Internal DHCP Server.
The controllers contain an internal DHCP server. This server is typically used in branch offices that do not already have a DHCP server. The wireless network generally contains 10 access points or fewer, with the access points on the same IP subnet as the controller.
In this case, the APs will not be in the same subnet as the Managment Internet.Is it a mistake to use the internal DHCP with upto 25 APs (3 WLANs)?
i see there is an option to "allow password change" or "force password change" for guest roles in the NGS. But when i created a guest account using this guest role, after webauthentication , there is no prompt to change password. Is this the intended behaviour or is there anything else that i need to configure. Looking at it, i am not sure how the NGS would allow a "guest user" to really overwrite the password by allowing password change. ? is that not a security risk as well for the NGS ? my setup has 5508 anchor controller and NGS communicating via RADIUS.
I have been unable to get IPSec working between my WLC 5508 and a server 2008 NPS radius server. Any luck configuring this? I have opened tickets with both Microsoft and Cisco, but so far have not been able to configure it properly.
I am trying to follow the Fips guide for the WLC5508 and it wants to encrypt the connection to the Radius, either with PSK key wrap or IPsec. I have the options for Ipsec only as the Windoes NPS does not support Key wrap from what a previous user confirmed for me here on the board.. But then found another post that states that the 5508 does not support IPsec?
