Cisco Switching/Routing :: 891W-AGN-A-K9 / Max Wireless Transmission Speed
Oct 12, 2012
I have had trouble to verify the support wireless speed and band that CISCO891W-AGN-A-K9 supports. I saw on a vendor website that it supports a max wireless transmission speed of 54Mbps but this seems low for what is supposed to be the current model wireless router which is supports 802.11n. What the maximum supported wireless speed and whether 5Ghz is supported? Plus I am thinking about purchasing it for my home wireless network (upgrading from an 871W).

I have an 891w that started acting up recently. Radio dot11 0 is reporting its a b radio. When it is actually an n 2.4 radio. Of course that radio is not allowing any clients to connect to it at this time. I have tried updating the firmware to the latest, tried a hardware reset but still a nogo.
sh interface output.
Dot11Radio0 is up, line protocol is down
Hardware is 802.11B Radio, address is 0000.0000.0000 (bia 0000.0000.0000)
MTU 1500 bytes, BW 11000 Kbit/sec, DLY 1000 usec,

I've got an AIR-AP1142N-E-K9 access point, i've got the Radio0-802.11n(2.4ghz) enabled and the 5.0ghz disabled.
i've got my client real close to the AP and i only get a connection speed of 72Mbs.
Shouldn't i get 150mbs? Maybe some wrong configuration?

I have been disappointed by the range of the EA4500 compared to previous routers, but I am most puzzled by it's behavior. I may get an "excellent" connection close to the router (one room away) and speeds up to 65 Mps, but after a few minutes of surfing the web the signal strength and speed can drop substantially.
The problem is the worst at a distance (one floor down in our house, maybe 30 feet away in total) where the signal strength may start at "good" and a speed of perhaps 30 Mps, but then after 3-4 minutes drops to "poor" and maybe 5 Mps.

I have a client that that is installing a new network. They have requested the use of an CISCO891W-AGN-A-K9 mostly to be consistent with upgrades perfomed at other sites. I agree with the use of this router, so that's OK. The issue is that they have requested that I use the integrated PoE available on this model. I'm also OK with this as it will make a much neater installation. However, I can't seem to find much information on how to get the integrated PoE. I need clarification as to whether I can get a kit to upgrade this router. I generally purchase from sites like newegg or cdw (I'm an independent contractor) and I can't seem to find one with it. I have found some information on 800-IL-PM-4 and 800-ILPM-4 (who could confuse those ). Are they the same or different? Which one is the correct one and does it include the AC power adapter and can if be retro'ed into a router without the PoE?

I believe I have the steps done at the IOS to config the WAN port for SSH, but I still can't connect to it. I have "logging console 7" on so I am able to see that the router is dropping my TCP session requests. I figure this is just the built-in zone-based firewall at work.
Is there a very straightforward process, via the IOS, to allow SSH inbound on the WAN port? I'm not very familiar with the IOS other than basics so while I know how to do things like "transport input ssh" and "login local" and such on the vty 0 4 line, I have no idea whatsoever on what I should do with the firewall stuff. I believce the WAN interface is already a member of the outside zone though so I imagine one just has to somehow include ssh (preferably on a non-standard port) in the exceptions on the firewall somehow.
I have been poking around for a step-by-step IOS guide for this but only find info on configuring SSH itself but not how to open the firewall to allow the connection for it through.

I have an 891w as my edge device for my home office. I have a VLAN for family use (wired and wireless) that routes out to the internet just fine. I have a second VLAN assigned to a VPN tunnel that backhauls traffic to my corporate network (wired and wireless) and all of the traffic gets to the corporate network fine when I am on that VLAN.
However, while I am on the VPN VLAN, no traffic gets to the internet. I believe it is because I have the gateway of last resort (0.0.0.0) set to the WAN IP address provided by my ISP, so DNS is resolving against corporate, but because there is no specific route, it is trying to dump the traffic back out the WAN without traversing the VPN tunnel.

I'm new to using Cisco Config Professional Express but a lot of things are just "off" with this utility. But my problem for this post is specifically the 891W's internal access point, or initial access to it.
My situation is that I have some 891W's. It's my first time working with them, as well as with CCP Express (2.5). After isolating the router and my PC to their own network, using the IP my PC got via DHCP frmo the router I opened a web broswer and connected to the router. The initiial configuration wizard came up and I went through the various screens. One of those screens had basic config info for the internal wireless AP which I provided. Somewhere in that screen it asked for a Hostname for the AP, and a password. It doesn't askfor a username though. To ensure I wouldn't run into confision, I made sure to set every password I ever get asked to configure as the same thing so the AP's password was also the same.
However after I finish with the wizard, the java-based CCP Express begins prompting me for first the main router credentials which I provide and it gets the router config, then it prompts mefor the username/password for the Access Point. First of all, the initial config wizard had never asked me for the username for the access point, only the hostname, and the password. I had assumed it was just going to use the main router username, or perhaps a blank username.
In any case, nothing I type ever works. I've used cisco/cisco, or a blank username with my new password, or the same username as the main router with the password ---- nothing. This is now the 4th time I have completely Reset the router to factory defaults and while I am learning the use of CCP Express through repetition, I'd also like to get this thing configured and out the door so my customer can use it.

I am trying to configure the FE8 (WAN port) to connect to the Internet. We're swtiching ISP'ssoon so this router was set up at my office and has since been deployed at the client site. So far it is just plugged in and powered, with a console cable attached but no LAN cabling since this router will replace an existing one using the same addressing (except the WAN settings of course). So for now I am just focused on working on the WAN side since I have the ISP's cable modem attached . I had intiially used CP Express to config the wan port with an IP and mask and the various port forwarding options I intend to use. Now, connected via console cable, I tried pinging the IP of the wan port, which works. Beyond that, can't ping anyting (8.8.8.8 - a Google IP), also can't resovle any DNS names which makes sense with no apparent connectivity. Likely my config is just imcomplete. Nowhere in sh run do I see a Default Gateway, yet this ISP did specify one so I assume I need to enter it. Not sure what's the right way - I get confusing results on searches telling me either to use ip default-gateway or ip default-network. I want to think that it's as simple as entering in the IP but so far I've learned with the IOS that you never do anythign without knowing all the possible implications, which I don't. Also while I am at it, I don't know what I should have for DNS entries. This router will not be a DNS server for any internal systems that function will be managed by the two Windows 2008 R2 DNS machines. The ISP has also provided two IP's for their DNS servers. I thought it would be a simple matter of just adding two entrires via ip name-server command, which I did. So now I have four entries, first the two internal servers (inaccessible currently due to no LAN cabing to this router), and the two ISP servers. Can't ping those either, but again there's no default gateway.

I'm working with some 891W's that have the internal 800-series AP. I have this router set up initially using Cisco Config Express, then, using Cisco Config Professional 2.5 I set up the firewall and other featuress that CCE doesn't do. Overall this is a very simple router, meant to be a small business Internet gateway device but is currently in my lab.
The intended WLAN setup is very simple. One SSID, with broadcast enabled, using WPA2-Personal. Auth: open Encryption is both TKIP and AES-CCM.
However no matter what I do I cannot get thhis thing to broadcast . In the past I had sometimes run into issues where if I had more than one AP running independently it would cause a channel conflict and one or both would cancel each other's radio, so I disabled all other AP's in my vicinity.
Also I've had issues in the past where f I enabled both TKIP and AES, sometimes clients can't find the AP as a result. My solution had been to disable one of them leaving just the other - no change here however.
Via the IOS, ssid config shows mbssid guest-mode which I believce is default.
Interestingly, if I do the following:
ap# Config t
ap(config)# dot11 ssid <myssid>
ap(config - ssid)#guest-mode
end
I end up with both "guest-mode" and "mbssid guest-mode" in the sh run for the AP, and voila, my AP broadcasts the SSID. However clients end up joining without any security at all, no prompts for pre-shared key or anything.

I have an 891W router that requires a firmware update to fix a bug wth the internal AP where all you get when accessing it via the CP Express ("Launch Wireless Application", which is just opening another web browser to your AP) is an Enter button. This issue seems to be common so I found a thread, though for the 881W (but same process) where the fix is to update the AP's firmware.
So I downloaded ap801-rcvk9w8-tar.124-21a.JY.tar from cisco.com, set it up in my tftp server, and at the console ran the following from the router:
Router#service-module wlan-ap 0 session <enter>
This brings me to the AP.
I then type in:
InternalAP#archive download-sw /force-reload /overwrite tftp://192.168.0.71/filename.tar <enter>
It seems to go through the process of re-imaging the fw but the end result now after it is done is that I cannot access the ap at all and the hostname has been screwed up. So now when I go to the AP (via Router#service-module wlan-ap 0 session <enter>), this is what I see:
AP6400.f177.d0ee>
If I type "enable", I get no username prompt but I do get a password prompt, however my pw no longer works. Also the IP address of the AP (192.168.0.2=) is no longe rpingable.
I did save the log of the console session for the (failed??) firmware upgrade process - the only odd thing I recall was that it seemed like it was trying to enter part of the update process commands but instead the router was interpreting them as a DNS lookup or something. Kind of stupid process it seems but anyway I am quite lost. Don't know what it'ssuch a challenge to update firmware.

I have an 891W that I initially configured using CCP Express (2.5). So it has a WAN IP set, and through CCP Express I had enabled via the checkboxes the various default settings for security. This includes zone-based firewall. I then added a number of NAT entries in the setup wizard.
What never occured to me at the time was that I should have added entries that allow for remote access. So it seems I've locked myself out of accessing the router via the WAN interface even though I know it's IP. I'm sure it's just a matter of adding port exceptions for SSH and/or whatever port(s) CCP uses.
So I"m wondering what the proces woudl be. In the IOS while showing the running config., I see pages and pages of class-map stuff which at present I don't know enough about to risk editing anything directly. But maybe I don't have to? What would be the best way to, for example, enable SSH access through the firewall? I already have transport input ssh set on the interface itself so I believe it's ready to allow the connection, just that I can't get to it via WAN int. so I assume it's the firewall.

The coaxial"or any other metal cable" was using for transmission signals(before fiber optic) the coaxial need repeater every 2 or 3 Kilo meter,because the signal will be attenuation when pass through the cable,when we transmission electricity to far places ,we use transformer to rising the voltage to 10000 or 100000 volt

I am having problems connecting an 891w to a WLC, is it possible to have to separate vlans, one for the Lan ports and another for the AP module.
I do not want the AP part of the 891w in autonomous mode. The WAN port of the router will be connected to a DSL type service.
Is there a guide or something to get a 891W to connect to the WLC?
I would like to have users on a data vlan (vlan1) connecting to the network like a normal router, then the AP module to connect to the WLC via a different IP probably vlan 2
On the WLC itself i do not see any attempts in the logging.

I have an 891W with the internal AP. I want to update the AP's software but can't find anywhere to get it on Cisco's site. If I go to Download All, Routers, 800 series, 891W all I can choose is IOS, IOS ROMMON and upgrade to LWAPP. If I go to Wireless Wireless integrated service routers, 800 series, 891W I get IOS and IOS ROMMON.

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!

i have a 5500 series WLC connected to a switch through a trunk port with 2 v WLClans. the connection works fine, but sometimes it loses connectivity. it works again rebooting the wlc.
When the problem presented, i checked the cpd neighbors on switch and it didn't show the wlc, and i checked the cdp neighbors on WLC and this shows the switch in its neighbors list. i also checked the port counters on WLC and the receiver counters keep increasing, but the transmission counters remains in the same value. then i can see that only the TX side on the controller is down, if i restart the WLC the problem disappear temporarily.
Is there a misconfiguration or a wlc bug related to this behavior?
The switch is a Catalyst 3560
The WLC controller code is 6.0.188.0

Any issue creating a guest vlan to use the WIFI on an 891W router? The IOS is version 15.1. I have created discreet Vlan's and setup subinterfaces on both the WLAN_AP0 and GigaEthernet 0 interfaces with dot1q encapsulation. The client will receive an IP from the pool but cannot ping or connect beyond the default gateway.
The external interface is using Nat overload and all wired clients are successful in connecting to outside addresses. I have insert a permit any statement in the acl which affects the external port but still no success.

I have had a DIR-655 for years, and this is a treat - channeling everything from IPTV, to a fast fiber connection, transfers - no sweats.
Then I had to setup a router for a friend, and recommended the DIR-615.
Setup the router, and max it would connect with was 150mb - I changed the settings accordingly: auto channel scan channel width: auto 20/40mhz
So this "opened" up the 300mb speed - however only for 5 mins, then it falls down to 150mb.
My laptop (lenovo) connects to the dir-655 just fine at full speed, and this is also the machine I used for testing the dir-615.
It's ax Hx firmware, FW: 8.04
What I can conclude by using inssider, and xirrus wifi inspector is that it generates 2 channels - and then after 5mins of connectivity looses a channel, and then the speed drops.
I got a new router from the dealer, same issue. Then a friend of mine lent me an ancient dir-615, and interestingly enough this had the same configuration option of "Transmission rate" in the wireless settings page! Just like the dir-655. and also connects at 300mb...

But same condition with above, cheaper wireless router no problem at all. It happens only with EA4500. And there are no any parameters setting menu actually.

I have 5x Cisco 2960 and 1x Cisco 2960G. All of them are using IOS Version c2960-lanbasek9-mz.122-55.SE6.bin I'm having poor inbound speed with ALL of the Cisco 2960 (except 2960G) although the outbound speed is normal. The port is 100Mbps Full-Duplex, but the max inbound speed on a single connection is around 35Mbps. With the 2960G, I can get max 1Gbps inbound speed on a single connection.
I checked everything and still not know why the 2960 switches can't get max 100Mbps inbound.
