Cisco Wireless :: Options For 881W ISR?
Sep 27, 2012
I'm putting together a design for a new office with the following requirements:
10 VPN users.For Ethernet – 24 ports POE 10/100/1000
Probably go with VZ FIOS so EthernetAbout 2000 square feet so 2 WAP's should do it I'm thinking a CISCO881W-GN-A-K9 ISR with a SRW224G4P-K9-NA switch should do the trick. This will give me an integrated AP but I need a second one. Do I need to order an autonomous one or does the 881W do some sort of WLC function?

Is the max wireless speed on the cisco 881w 54mbps even though it has 802.11n hardware? What about the 891w ?

The 801 AP on my 881W reboots every other day or so, randomly, on its own. The router / AP works great otherwise, no other issues. I checked the error log and I see no indications of why it would be doing this.

I have a Cisco 881W configured for wireless (just a PSK, nothing special). I can get out to the Internet OK and browse to everywhere except my own websites.
It runs on a connection that does not connect directly to my network, but our website is available to the world externally.
Now, from the router a traceroute and ping work fine to our website but from the wireless connection I can get to everywhere else on the web but our website. A traceroute just stars out. I'm using 8.8.8.8 as a DNS server and nslookup resolves the DNS.
I can't set a DNS server or domain server on the ap on the 881W so are there any commands I can use to see what's going on?

1 router 881w with a site-to-site VPN connected to a switch and a wireless which allows internal users to access the VPN via wireless (this is like a backup, if the switch fails, then they can use the wireless). Everything's working fine so far. Now I want to configure a second WLAN for guest but I'm not really sure if this configuration will work:
ROUTER:
ip dhcp excluded-address 192.168.100.1 192.168.100.200
!
ip dhcp pool GuestNetwork
network 192.168.100.0 255.255.255.0
default-router 192.168.100.1
dns-server 8.8.8.8
[code]....
If it's not clear I want that everyone that is connected to the guest WIFI receives an IP address from the range I wrote before and then goes directly to the internet.

We've had a Cisco 881W set up in one of our remote offices for a while and the wireless has been fine. Yesterday I got a call saying that the wireless was no longer working.
I went over and it's true, the SSID is no longer broadcasting. I reloaded the router but it's still the same. I tried to get access to the embedded ap and I get this
RTR#service-module wlan-ap 0 session
% telnet connections not permitted from this terminal
RTR#
Now I've not changed anything on the configuration since it went in and it was working before. Has the embedded ap died? The embedded ap is still showing as a component in show hardware.

I recently purchased a new Cisco 881w router (last Friday).I have configured the 'wired' part of the router with little trouble, but the wireless side is proving a little challenging.I have read a number of posts complaining about the firmware version installed on my device being very buggy.The version of the firmware on the wired part is: Version 15.0(1)M8, however, the firmware on the wireless side seems to be: Version 12.4(21a)JA1 - the version reported as buggy. The former has a version date of 2012, with the latter being 2009.I have tried to download a newer version, but the site is asking me to provide a support contract.I wouldn't mind buying a support contract if the thing worked in the first place and I was trying to add some feature after it had been working for a while.

We had setup a wired/wireless LAN using Cisco 881W router for one of our client. Wired lan works OK but we have issues with wireless. Users on wireless LAN can connect to the wireless network, but cannot browse the Internet. The wifi network does not give out an ip address to the client so client cannot get to the default gateway and Internet. Not sure what part of config does not work.

I have a Cisco 881W and I would like to basically some how bridge the Cisco router to my netgear router. This is what I'm trying to achieve:
Cable Modem ----> Netgear Router ~~~~~ via wifi ~~~~> Cisco 881W ------> FastEthernet Ports
I've tried setting the Cisco 881W with station-role non-root with the SSID of my netgear router, but I get the error %DOT11-4-CANT_ASSOC: Interface Dot11Radio0, cannot associate: No Response whenever I try to bridge it.
Is bridging the Cisco router via wifi to the Netgear Router something that is not possible or is it an error on my part?

I'm setting up a couple 881W cisco routers to use Unified wireless and am running into a bit of a brick wall.I've read through the "Upgrading to Unified Cisco Software" section of the following article:[URL]The problem is, I can't run the "service-module wlan-ap0 bootimage unified" command. The keyword "bootimage" does not exist. The router is licensed for advipservices and I'm running version 15.0(1)M4 on the router. AP is currently running version 12.4(21a)JA1. why the bootimage command doesn't appear? Will I need to downgrade the router IOS to 12.4?Additionally I'm having trouble finding an answer to the following:Is there a way to set up the embedded AP on the same network as the Data VLAN on the router, or do I need to create a separate IP network for the embedded AP? I've tried using 'ip unnumbered vlan10' (vlan10 is the data vlan) on the wlan-ap0 interface but then when I try opening a session to the AP it doesn't connect.
bcp4n51001#service-module wlan-ap0 session
Trying 10.199.62.1, 2002 ...
% Connection timed out; remote host not responding
This is my Vlan10 setup for one of the routers:

ip helper-address 10.151.103.254

I have an integrated 881W with a built in 801 access point. I'm interested in increasing the range of my AP. I'm interested in considering any configuration changes while still maintaining support for N. I've included a copy of my running config.As well, I've heard of high gain antennas. I'm using the default antennas that came with the 881W. If there are better antennas that I can buy to increase my range, I'm interested in considering that as well.

I was trying to upgrade the IOS image of the AP and I did a wrong manip.
I downloaded the IOS image (ap801-rcvk9w8-tar.124-10b.JA3.tar) from my TFTP server to the flash of the AP. Everything went find so far. But than I did an archive archive download-sw /overwrite ap801-rcvk9w8-tar.124-10b.JA3.tar and my AP reboot in LWAPP mode.
I should have done: archive download-sw /overwrite tftp://10.0.0.1/ ap801-rcvk9w8-tar.124-10b.JA3.tar instead!
Now I don't how to go back to autonomous mode. archive commando is not available anymore in LWAPP mode.

I have a Cisco 881W that will no longer boot/operate properly if the internal radio card is installed. If the card is installed, all I get is the following...
System Bootstrap, Version 12.4(22r)YB5, RELEASE SOFTWARE (fc1)
Technical Support: [URL]
Copyright (c) 2009 by cisco Systems, Inc
[Code]....
if I do a dev I get nothing. If I do a dir flash: I get "bad device name". My cookie shows FF in all positions.
If I remove the entire WiFi Radio card (both boards), then It boots fine, cookie appears intact, devs appear, IOS loads, just without the WAP.
Any chance this is a matter of a file getting deleted or corrupted or is this certainly bad hardware? The router sans Wifi appears fully functional.

After moving my PC for the 3rd over the past year ive decided that having a more wire-"less" option may be the better option as supposed my previous method of having a 10m ethernet cable from my switch to my PC. ive looked at two options, first the powerline HD (was drawn toward the belkin 1gigabit ones as i have a gigabit switch) or to remove the cable completely and using a USB wireless dongle (similar to the Edimax EW-7811UN Wireless 802.11b/g/n 150Mbps Nano USB Adaptor) . i havent had much experience with these USB wireless things as i used be put off by the compatibility and config (software stuff). i have a 3com wireless 54mbps.. PCI card but i cannot install the drivers for it on my xp 64bit machine.

I've got a number of 3502i's that I need to mount in a new classroom that does not have any ceiling (except the floor decking above). Ceiling is roughly 30-50' up. Contractors are going to run several 2" (or whatever we want) metal pipes from the ceiling down to a more reasonable level to mount the access points on and get below the hvac ducts/etc in the ceiling.
Problem is I can't find any bracket or mounting options for this! What are others using in this situation for mounting one of these access points onto a metal pipe such as this? I've checked Oberon Wireless, Terrawave and I don't see anything glancing through the product catalogs. Anyone mounting access points this way?

Our company is moving to a new location temporarily and we will be looking to do wireless for our network instead of wired. We have a dell power edge 2900 server running windows SBS 2008 and a switch with more than enough ports for what we need.What i need to know is how exactly to do the wireless and what hardware would work best for us. We plan to have approximately 45 computers hooked into the server and have some wired but for the most part wireless. Also we would want to look into advanced security options for our wireless set up as we will be in the same building as a few other companies.

I'm using the e4200 in a big old house with lots of walls, including rooms separated with brick. Wiring access points would be difficult given the problem of pulling wires. I do have lots of kids and devices connected including DirecTv, iphones, ipads, laptops, and PS3. Is there a range extender? Do I care if an extender only supports 2.4Mhz if I use the same SSID anyway?

I own an AG214 ADSL2 router that I use for my desktop PC. I now however also have a WRT54GL for wireless connection. I connected the WRT54GL to my AG214 via ethernet. Everything works fine, I have wifi and I can use it to connect to the internet. However when I go to my router (192.168.x.x) I can't seem to be able to find a wireless tab to configure my wifi settings. The network right now is unsecure and has a default name (linksys). How do I access my wireless settings? When I access my router it does go to the AG214, do I need to access the WRT54GL? If so, how do I do that?

CISCO881W-GN-E-K9 vs. C881W-GN-E-K9. What's the difference between these routers?
For example, the CISCO881G-K9 has a 3.5G ExpressCard Modem and the C881G has an embedded one with GPS and 3.7G in most versions. The C881G is, for all I know, the newer one. But for the two mentioned above, I can't find any differences at all. The C881 is listed in the Teleworking section of the data sheet. But there is no information whatsoever about any feature or license differences.

I have a Cisco 881W router. It has historically run IOS 12.4 (20.T3) without issue. I recently upgraded the IOS to version 12.4 (24.T5). Once I made that upgrade, my ability to fully throttle my downstream bandwidth became seriously limited and variable going from a steady 6Mbps to an unreliable 2-3Mbps. No other changes were made to my environment. The degredation in performance was so bad that my AppleTV would no longer stream Netflix or YouTube.I downgraded back to the original IOS 12.4 (20.T3) and the downstream bandwidth and variability issues disappeared. As well, my ability to stream movies or videos with my AppleTV on Netflix or YouTube returned without issue.I wonder if upgrading to IOS 12.4.24.T5 enabled some new commands that I'm not catching or there is something else at play that I'm totally missing.
