Cisco Wireless :: AP541N / Can't See Other Computers On Network Through Wireless / Wired OK
Jul 14, 2011
Our wireless clients that connect through our AP541N cannot see other computers on the network. They can ping other computers by IP and host name and access the internet OK. Mapped network drives can be connected initially but are very unreliable and always end up disconnecting. Restarting the computer does not work. When these computers are wired they see the network as expected. why my wireless network would behave differently then the wired? The wired and wireless networks are on the same VLAN. The wireless clients are all Windows 7 systems.

I have a dell desktop running windows vista that connects to my wireless router with a cable. I have an HP laptop that is running windows 7 that is wireless.When I look at network computers on the dell I get an error message that says that the computer is not accessible. The same thing happens when I try to log onto the desktop from the laptop. When I try to run the network wizard from the desktop, I see see connect to the internet, connect to a wireless router or access point, setup a dialup connection and connect to a workplace.None of them make sense but I tried connect to a wireless router and got a message that said to set it up manually or set up a flash drive, neither of which makes sense. I tried set it up manually and all that happened is the router setup screen opened up.I tried the same thing on the laptop and the setup the network wizard opened a screen that said choose a wireless router or access point to configure, but nothing ever showed up on that screen.

I'm sort of new to networks so I'm not sure if this is even possible but what I'm trying to do is set up a wired network between computers but leave the wifi on the computer as how it connects to the internet. I'm using two computers connected through a lynksys router(not connected to the internet) and ethernet cable, and one of the computers has a wireless card that connects to another router that is connected to the internet. i can set up a network between the two computers but then the one can't connect to the internet(even though it says it is connected the network with internet),

How do we begin troubleshooting a wireless device accessing the network that a user is complaining slow accessing network recources? We are getting complaints that it is slow, when connected to internet we get about 20 MB. There is only one user connected.
We switched to 2.4 GHz 802.11n from 802.11 bgn, but are told that did not work. We also have it on its own VLAN.
Product Identifier:AP541N-A-K9 Hardware Version:V01 Software Version:AP541N-K9-2.0(0) Device Description:802.11n Dual Band Access Point - Single Radio

We have two Cisco AP541N running our wireless network in the office. They're configured with the same SSID, so that people are automatically switched between the two access points depending on their location in the office.
Frequently we are experiencing very poor performance of our wireless connections and it seems to be related to when 4-5 clients are connected to one access point. After restarting it (which also moves the 5 clients to the other access point), the performance problem goes away for a while.
I've upgraded one to firmware version AP541N-K9-2.0(1) (the other is running AP541N-K9-1.8(0)), but it doesn't seem to work.

The facility provides WiFi access. I'd like to configure his router to access the facility's WiFi, as WAN access to the internet while providing DHCP service to the wired ports. The idea is to use the 4 wired ports to provide inter-connectivity to each other and internet access via the router's wireless connection via wireless for internet access by the wired client machines.I'd also like to firewall the wired devices from access by other users of the facility Wireless network.Can I do that? How do I configure the wireless aspect of their Belkin Share 300N? What other settings do I have to set.

Our wireless environment consitst of 5 AP541N's configured with 2 VAP's. 1 VAP is for our private network and the second for unsecured guest access. I am wondering what the preferred wireless mode is to maximize network speed? We only have N devices on our network and our mode is currently set to 802.11 b/g/n. Would 2.4GHz 802.11n be faster?
Does the Transmit Power setting have any effect on speed? Or just range? Any other settings on the Advanced Settings page effect network speed.

Cisco 2504 wlc, 1142n ap, windows radius server.
When I click on Network, the only computer that shows up is mine. If I am hardwired then everything shows up (Servers, other workstations). Is this a problem with the radius server or something on the controller?

I am having problems authenticating client computers onto the wireless network using a Cisco AP1252 via radius
Setup:
I have a Cisco AP1252 wireless Access Point connected to a Cisco ASA5510 on subnet X.X.5.Z The access point ip address is X.X.5.101
The ASA on another port is also connected to the wired network on a different subnet X.X.0.Z
On the wired network are two radius servers - Ubuntus servers running freeradius which are running fine and reliably authenticate wired users for ssh connections to the ASA and importantly to the AP1252 as well (The radius servers ip addresses are X.X.0.191 and X.X.0.192)
Problem:
When a wireless user tries to connect to the wireless network via the AP1252 after being disconnected form it for a while (or after waking from a long sleep) they are never authenticated. They just try over and over and never obtain an IP
Interestingly in such a case neither Ubuntu server shows any sign of receiving an authentication request from the AP - Both ubuntu servers are running in debug mode so they show any activity - there is none
Oddly:
If i try to authenticate a user wirelessly to the AP and leave it in the usual state of trying over and over (with no visible activity on the ubuntu servers) BUT then go to a wired machine and attempt to authenticate an ssh connection to the AP1252 using a terminal command ssh user1@X.X.5.101 THEN as soon as I hit enter on that request (and before I enter a password for the ssh connection) THE WAITING WIRELESS USER IS IMMEDIATELY AUTHENTICATED (and the ubuntu server shows the authentication activity for the wireless user
I really do not understand this and cannot use this method to facilitate wireless user authentication 
What might be causing this behavior - it seems like the AP sleeping and the wired ssh request wakes it up so that it sees the pending wireless user waiting and then acts on that completing the wireless user authentication request.

I have a client that has 3 AP541N's and they want to enable guest wireless access. However, their VOIP provider has their managed switches locked down so we can't add VLANs, etc.So I cannot touch the switch or router config on this LAN.
Looking into AP541N documentation I see VAPs mentioned, can I enable those and have secure guest wireless access with the same private IPs that the rest of the LAN use right now? (That is, the employees are 192.168.2.x and the guest wireless users would also be 192.168.2.x.)
Or do I need to do something else to properly enable guest wireless? Like add another piece of equipment? I did try to add a Cisco RVS4000 to the mix but it wouldn't pass the VLAN across the switches that I setup for the guest wireless SSID. goal is to leave the switch and router in place, and work with the AP541N's that I have and get secure guest wireless.

I recently decided to buy a DIR-655 router to create a wireless network in my home. I hooked it up last night and speeds look fine with my rr standard 10mpbs service. However, I decided to check the wireless status and my macbook, macbook pro, and my desktop computer are only getting at most 130mbps. Is there anything i can do to maximize this and go beyond 130mbps

I have 2 AP541n's on firmware 1.9.2.They provide two SSID's on different vlan's, so far so good.However, on the wireless neighbourhood tab it only shows one of the SSID's as being in the cluster.The other SSID does show, but only when not in cluster or both is selected.I can access both SSID's fine, its just this management page that doesnt quite work.I have removed and added them again, it seems that only the SSID first in the list wireless -> wireless network setup page shows as being in the cluster.Have I missed something or is this a feature?

the site has a private wireless network for which I pay a yearly access fee. This gives me a code I can use to gain access each time I connect. We used to be able to have all our family's laptops, etc., connected at the same time using this code, but the site has recently changed the configuration so that we can't do this. Is there any way we can share the connection made by one computer so that we can all access the Internet at the same time? The site is in a remote location that gets poor mobile data coverage and landlines are not an option. The yearly fee is already high, so I can't afford to pay for multiple subscriptions.

I have 3 computers all running Windows 7 64bit. I had to move my desktop computer to a different room with no ethernet connection so I purchased a Linksys AE2500 usb wireless adapter for it. My router/modem is a Actiontec 2000 which came with my internet. When I have my desktop on and connected to the internet it slows down all the computers on the network and it is really slow. My question is do I have something installed wrong? I used the driver for teh adapter from this site and nothing else has changed.

I have a E2500 connected to a cable modem as the base of my home network. Hard wire connected to the E2500 is an linksys 8 port hub and a couple of computers. The 8 port hub is connected to a couple of computers and a xbox. I have the hub as a distro point to cut down on wiring. Wirelessly connected to the E2500 are a variety of laptops, netbooks, ipods, an ipad, a playbook, an iphone, a android phone, a wireless printer and a Ps3. Most of the devices are just using the wifi for internet access. Most devices have been setup with their own ip addresses to avoid ip conflicts. The computers and laptops/netbooks are running either Windows XP, Windows 7 or Mepis Linux. Up until now everything was going as good as can be expected, all the computers could see each other and most could transfer files between each other except when Windows gets picky.In the last few days no computers can see each other. Windows or Linux.Everything can accsess the internet and wirelessly print still just can't see each other. I reset the E2500. I updated the firmware on the E2500. I installed the Cisco Connect software (just in case I was too stupid too setup a router). Still nothing. I can ping other machines from a command prompt in windows or a terminal in Linux and get a good ping back. In the router setup via a browser I can go to the status page and see other devices on the local network but most are just ipods, ipad, playbook and the wireless printer, If I go to the administration page / diagnostics I can ping other computers and get a good answer. I just can see them from each other. I think I've rebooted every thing at least once. Yes the workgroup names are all the same (workgroup) and yes file sharing is turned on on all computers.

I purchased a E3000 Router to replace a dead Dlink about a week ago..I have 4 wired computers on my network. All in the same workgroup. I have 2 computers connected directly to the E3000, and 2 computers connected to a ProCurve managed switch on the other side of the house. I can ping the computers on the switch side of the network but i cannot see those computers in the network section of windows 7. I can also navigate to them via \ computername.

We have a customer which is using ISE with 802.1X in order to authenticate computers. All the computers have their own certificate and most of them can be authenticated fine! The issue is that some computers cannot be authenticated.The port configuration the authenticator (Cisco WS-C4510R+E IOS 151-1) are configured exactly the same: [code]
But for some reason some PC cannot be authenticated. A wireshark capture on the computer not working shows that the computer receives a EAP Request Identity and also send a Response Identity to the switch but then nothing happens more: So the process is stucked in the EAP-Response/identity. I attach a debug capture on the switch for one of the computer which cannot be authenticated.

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.

I've been using "Linksys by Cisco Wireless-N Home ADSL2+ Modem Router WAG120N". I can restrict internet access to only 8 computers using their Mac adresses but there are no ore entry fields for Mac adress than 8. What shall I do when I need to block internet access to more than 8 computers say 20 computers on wired LAN? I don't like the option blocking the internet access via IP address. I found they are not that effective as the option Mac adress

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?

I just installed a brand new AP541N-A-K9 (running AP541N-K9-2.0(1) software) and cannot seem to add a SSID. I've tried both from CCA and directly from the Web interface (Wireless:Wireless Network Setup menu). The Add Another button doesn't seem to do anything. I've even tried multiple browser versions.
