Cisco Wireless :: Enabling QoS On 871W?

Aug 9, 2011

I bought an 871w second hand with 124-24T IOS on it.  I would like to enable QoS.  When I use Cisco Configuration Professional to manage the router I click on QoS and it says it is not available.  I know that the router itself is QoS capable.
 
This is my first time dealing with a router such as this and I wonder what I need to do to enable QoS.

Cisco Wireless :: Two Types Of Wi-Fi Authentication On 871w?

Sep 23, 2012

I have a small wireless network, which consists of three AP1121G with c1100-k9w7-mx.123-8.JEB1 ios and one 871w with c870-advipservicesk9-mz.124-24.T1.  I've configured two different ssid's with individual authorisation types - ssid_1 with eap, ssid_2 with wpa. All three ap's works as it should be, but 871w authorises only eap connections, and all other types are rejected

Cisco Wireless :: How To Configure Wi-Fi On 871w Router

May 12, 2013

I'm trying to configure WiFi on my Cisco 871w router withouth any knowledge in this area. And it's a tough one, couldn't do it just with google, hope this is the place where I can get it done right step by step if possible. Everything else works fine. I'm going to post my messy show run below. Everything I did on dot11Radio will need to be cleared I suppose.

Cisco Wireless :: Clients Losing Connection On 871W

Nov 5, 2012

I have a problem with myself a few other clients randomly disconnecting from my 871W. It appears that I am still associated but Windows 7 shows "Limited Access". I appear to be assosciated to the AP and I still have my ip address but I can't ping the 192.168.1.1 gateway (871W). I have also set my power plan to allow for Maximum Performance which I thought disabled PSP but the log is still showing errors.As a final note, after I reconnected by ip address (192.168.1.107) doesn't show up in "sh ip dhcp bindings" but I'm working.To correct the situation, I have to disconnect and the reconnect to the AP and then I am good for another day or close to it. Below are the log errors, config and a sh ver. [code]

Cisco Wireless :: 871W Unable To Ping / Contact Another User On Same Subnet

Jul 28, 2012

I have an 871 set up at home with 2 VLANs, both of these vlans present a strange behavior where an user is unable to ping/contact another user on the same subnet, however if users are on different subnet it seems to work [code]
 
According to the troubleshooting that I have done, the issue seems to be with the broadcast traffic, ARP request/reply do not reach another host on the same subnet (wireless to wireless or wired to wireless) however if the wireless device iniciates the connection  to wired,  it works fine.
 
I have tried to enable proxy arp on the different VLANs and BVI and different combinations but no sucess in order to get traffic across 2 wireless devices on the same subnet or a connection that is iniciated for a wired client to a wireless one.
 
I tried enabling and disabling dot11 arp-cache but no luck.

Cisco Wireless :: 871w Ethernet And Wireless On Single Vlan

Jan 16, 2013

I'm trying to setup a cisco 871w router in a very simple configuration using only 1 vlan. I have the FastEthernet interfaces setup such that when you plug in a client computer into one, everything works as expected. I'm now trying to set up the wireless portion. From what I've read on the internet, I managed to bring up the Dot11Radio0 interface and the BVI interface. It's a little confusing to me, but it looks like I need the BVI to bridge the wireless interface to the vlan? I'm not sure how it works...

Anyway the problem is that I can connect to my wireless network, but after authenticating, there is no ip address being assigned to the client. I don't think I'm bridging the interface correctly or something. Windows 7 gives me a yellow exclamation icon on the wireless tray icon saying "no internet access".
 
Here's my config:
 
enable
config t  
hostname [name]
 interface FastEthernet 4

Cisco WAN :: 871W Won't Route Between LAN And WAN

Jan 4, 2013

I am a bit green with IOS and have exhausted everything I can think of with this. The router passes the WAN test in CCP?Undoubtedly there are probably a few things in the config that are either redundant or totally unnecessary, but I have been trying a few things to solve this with very little success.I have no security stuff in here because I have triewd to keep the config as simple as possible to start with. I will add that after I get the routing working.
 
Here is my most recent config:

Cisco WAN :: 871w Cannot Ping Website On Internet

Jan 15, 2013

I have a cisco 871w router that I'm trying to incorporate into an existing network. I have FastEthernet4 (WAN port) plugged into an ISP device, which I don't have access to. I have the address set to use dhcp, which is successfully recognized and I see that the interface gets a valid ip address that I can ping with other computers on the same network.
 
Problems: I am logged into the router via the serial port and I cannot ping websites on the internet. I am able to ping sites that are hosted inside the WAN, but when I try "google.com" for instance, I see it sending out packets, but none are received. It resolves the hostname from the local DNS server, but there are no packets received.
 
I type into the console to set up the router. I'm missing a lot of stuff. This is what I've been able to piece together using google and the software manuals:
 
enable
config t  
hostname [hostname]
interface FastEthernet 4

[Code].....

Cisco WAN :: 871W Significantly Drops Speed On WAN Int When ZBF Is On

Jan 16, 2011

As soon as I add the interfaces of the router to security zones it significantly drops speed on WAN interface, below 1  Mbs. I noted this because I wasn't able to watch youtube. Moreover the bandwidth test from speedtest.net hangs and doesn't come to a result. Here below is the diagnostic example while doing that test. The question is what is going on? I have two iPhones and three computers in my network, that's it. My ISP bandwidth is 10 Mbs, so is this the router hardware limitations, or kind of malfunction or some misconfiguration down here? What could be done here ?

Cisco WAN :: Cannot Access Internet - Ping PC With 871W

Jul 23, 2012

I am new to Cisco and am studying for my CCENT certification. At the moment, I am attempting to correctly configure a Cisco 871W lab router. Since I have undertaken this task, I have run into nothing but problems. First off it was finding that the previous owner had left a password on it, having to purchase a new USB to DB9 adapter to pass the "break" sequence to the router, and then resetting the router in ROM Monitor mode.
 
Now, I cannot seem to configure the router correctly, and am quite stumped.
 
My ISP is Charter (cable internet), and the home network that I am using consists of a Motorola SBV5122 Digital Voice Modem, Motorola SB6120 Cable modem, and, ideally, should also include my Cisco 871W router.
 
When I connect my router to the SB6120 Cable modem, the router receives an IP address via DHCP and the WAN indicator light turns on.
 
I have a VLAN configured on the 4 switchports of the router, and it is setep to act as a DHCP server. However, when I connect my PC to rhe router via Cat5e Crossover cable, I cannot access the internet. The router gives the PC an IP address, yet all attempts to ping the PC from the router fail. Somehow, I can connect to the router via SSH though.
 
Furthermore, I can ping the 127.0.0.1 loopback address from my PC, but cannot do so from the router.
 
how to correctly configure this router to function as intended in my network situation, however, this is proving to be seemingly unsurmountable!
 
I have attached the config of my router along with both outputs and commands relating to my predicament.

Cisco Switching/Routing :: Difference Between 871W / 851 And FTP

Oct 10, 2012

I've acquired an 871W, because I'd like to use wireless, to replace my 851.  I Ft Pd the 851's configuration to my FTP server and then Ft Pd this to the 871W.  Save for the fact that this has a radio interface (currently shutdown), everything works save for FTP from the outside.  I can not even telnet to port 21 of any of the internal FT servers.  I can telnet to any other port (ssg, smtp, HTTP, https, etc.) but FTP will not pass.  What's the difference?

D-Link DIR-655 :: Enabling Wireless Causes It To Constantly Restart?

I play Diablo 3 and the lag that is created when the router restarts as well as getting booted, along with apps on my phones locking up are about to make me throw the DLink Equipment against the wall. 

FYI - the Comcast modem was just upgraded to the Xfinity Voice modem becuase I puchased two Voice lines last week. The issue was happening before the new modem was insatlled, and after. According to the Comcast Modem's status page (192.168.100.1) the modem has been online for 4 days, 6 hours, and 31 minutes. So I know the modem has not been cycling.

Cisco WAN :: Configure 871W Router For Internet Connection?

May 5, 2013

I've just started styding for CCNA. Bought a router 871W recently and spent two days straight trying to configure internet connection with no luck! I use console port to do the configs and SDM/CCP. How to do simple internet connection configs. I googled everything but it's still confusing. I can't assing any IP to FA ports 0 - 3. I used VLAN instead. But all tutorials use FA0 and when I try to assign an IP to FA0 it gives me some L2 can't be assigned or something... :/ And I'm also confused what IP address should I use for WAN. I plugged the cable from Modem to PC's LAN port and wrote down some IP addresses which I think I'll have to use to configure the router for internet connection. And here they are:

ISP IP: 76.114.54.255
SUBNET: 255.255.248.0
GATEWAY: 76.114.48.1
DHCP: 69.252.97.4
DNS: 75.75.75.75
75.75.76.76

Cisco WAN :: 871W - Router Configuration / Not In Possession Of Password

Jul 8, 2012

Recently, I purchased a Cisco 871W Router with which to practice/study for my CCENT with. Since I have made the purchase, it has given me nothing but headaches.
 
I cannot access the router to configure it, as the previous owner has a password set on it to access enable mode, which he/she has forgotten.
 
Here is the message that I receive when I attempt to log in into the router, to access enable mode. [URL]
 
Apparently there is supposed to be a one-time username and password of "Cisco", but this is not the case.
 
I have tried to do a password recovery, following this post discussion thread: [URL]

Unfortunately, this has not worked, and I am sure that I am doing something incorrectly. I am connected to the router via console cable and have tried power cycling the router and entering the break sequence, power cycling again, and then holding the space bar down for 15 seconds. The preceding has produced no results to speak of. Following, I set my terminal emulator, Tera Term, to the baud rate of 1200, power cycled the router, and held down the space bar for 20 seconds. I then immediately set the baud rate back to 9600. Nothing occurred, once again.
 
Furthermore, I have followed the password recovery instructions set forth by Cisco. [URL]
 
Nothing has come of these methods, either, and I do not see how they would work, or even apply to my situation, as Cisco seems to imply they should, as I cannot get into enable mode, let alone privileged mode or conf t mode, as the guidelines require.
 
Here is some info for troubleshooting:
 
OS: Win 7 HP 64 bit
Terminal Emulator: Tera Term
Router is not currently connected to any sort of internet connection. Only the power cord and console cable are properly connected.

D-Link DIR-655 :: Scheduled Enabling Of Wireless Seems To Reboot Router

Mar 1, 2012

A few weeks ago I noticed that at 9:00am sharp every morning my internet access dropped, and would come back up four minutes later.

The router is connected to a DSL-526B in bridge mode. My first thought was that the modem was playing up, so I factory reset it and reconfigured it.

I checked my ACLS and didn't see any rules that started or ended at 9:00 am so I just lived with it for a week or so until it got so annoying I contacted my ISP to see if they were resetting anything at 9am.

By accident, I saw that my wireless radio was being enabled aat 9:00am, as it had been for the last 2 years, when I first bought the router. But this problem has only started a few weeks ago.

So I changed the wireless schedule to see if that was really the cause for the reset, and sure enough, whatever time I changed the wireless schedule to, the router rebooted at that time.

I've also factory reset the router; twice; the first time I saved/restored my configuration, the second time I recreated all configuration from scratch.

why enabling the wireless radio resets the router, and why disabling it doesn't, and how to correct this behaviour?
