Cisco 871W wireless drops
I have a Cisco 871W that periodically will drop its signal. Any tips on how to configure this for maximum reliability? I set it to use chanel 2462.
I set it to use chanel 2462.
Sure, take this line away.
The problem could be the fact that you've specified to the WAP what channel to use. Now if you have a neighbor wifi using this same channel ...
Another thing: The 870W has two antennas. How many have you installed?

Help converting Cisco 871W Wireless configuration to Cisco 881W
I am in the process of trying to convert my Wireless setings over from our existing 871W to the new 881W routers. I have found some documentation http://www.cisco.com/en/US/solutions/collateral/ns340/ns517/ns430/ns855/white_paper_c11-492842.html but after reading it seems a) a bit confusing and b) doesn't cover how to handle multiple SSID's on different VLAN's.
My existing 871 configuration looks like this:

Can anyone lend a hand on how my 881W configuration might look like? You can't create multiple bridge groups and route IP (you can only do that over bridge group 1). I need to make sure that I can have two logically separated wireless networks (one for corporate and one for home) and that they get the right IP addresses from their right VLAN's.
Any input would be greatly appreciated.

Cisco 871W Wireless Performance
I have a newly configured 871W router that is giving me terrible performance via wifi. Via ethernet I am getting normal 100Mbit speeds. The router is configured for 54Mbit/sec, my computer thinks it is connected at 54Mbit/sec (see attached photo).

endAlso if I setup another router on the same frequencies I get perfect performance.
Another 871W or something else.
If it's another router model, I think you need to look at this. I have a strange feeling you're hitting the limit of the hardware. Not the wireless capabilities, but the router itself. -
Linksys access point is better than cisco's wireless router !?
I bought a Linksys WAP54G yesterday to
see whether my 871w is faulty. (Constant signal drops).
While I was testing, I noticed that WAP54G has a better signal strength than the 871w. What's interesting is, Linksys WAP54G only has a max power output of 15.5dbm, while the Cisco 871w has the max output of 17 dbm.
I used the netstumbler to measure the signal strength. Linksys WAP54G can constantly stay at -60dbm, while the Cisco 871w (with the max power configured) goes up and down (between -70 and -60 dbm).
They are both configured to use the same channel. I find this strange as to why a higher power output has a much lower efficiency compare to a lower power output.
Any ideas?Do you see this happening with all the 870 ISRs? I am suspecting a hardware issue. Can you check with a different ISR and see if you are observing the same behaviour ?

Cisco 871W - VLAN-Interface = 'Up/Down'
Hi,
I have configured our company's Cisco 871W per suggested configs found on the cisco web site, however, VLAN1, VLAN10 and VLAN20 interfaces won't come up (e.g. up/down) and it's preventing communication. Guess I'm expecting this to behave like a multi-layer swt/rtr (i.e. 3560). Can anyone help me on this?

Cisco Enterprise Wireless iPad Mini iOS 7.1.1
Hi,
I am experiencing issues with iPad Mini running iOS version 7.1.1 connecting to a Cisco Enterprise Wireless Network consisting of a Wireless LAN Controller.
The Wireless LAN Controller is running 7.6.120.0. All laptops, printers, iPad 2 & 3 models, iPhones, tablets, and other wireless devices work fine and do NOT experience connection drops. However, iPad Mini running iOS verion 7.1.1 experiences randomly Wi-Fi connection drops. Sometimes when this happens the iPad Minis will reconnect back to Wi-Fi, but most of the time, they do not reconnect.
I have been working with Cisco TAC but they cannot find any reason for disconnect.
I have changed the channel on the Wireless Access Points to Channel 6 and the SSID is open.
I also have 1 iPad Mini running iOS version 6.1.3 that works fine and does not experience these issues.
I also run a FileMaker 13 Database on these iPads using FileMaker Go 13. The FileMaker database is set to never disconnect on idle nor to never re-authenticate. But yet the iPads will disconnect from Wi-Fi which interrupts the connection between FileMaker Go and FileMaker Server.Try double -licking the Home button to bring up the recent apps display. Swipe up on the image of the App Store to terminate it. Restart the App Store to see if you get the proper operation.

Hello all.
I have just set up a new cisco DPQ3925 wireless router that Optus sent me to be able to access the higher speed internet I have signed up for.
I have a 4th gen apple extreme that I want to use to extend the wifi but when I try to update the settings via the airport utility I get a message that says it cannot do so, and to check it is in range and the wifi is set up correctly. I'm not experienced with these things but I can't think what I have done wrong.
Is anybody able to help me please.You cannot use the AE to extend wireless from a non apple router such as your cisco modem router.. they are not compatible..
You need to tie to the two devices together either with ethernet or something like EOP adapters.. They are about $120 and you can price match in officeworks. -
Is there a fix for the MBP wireless dropping issue?
I began to experience the Macbook Pro dropping wireless connectivity on my very 1st Apple in 2008. At the end of the day my machine was replaced with a new Macbook Pro mid 2010. It appeared to be working just fine until about 2-3 months ago when I started dropping my wireless printer connection. I searched the internet hoping for a driver update from HP or something from Apple and each time I found something, the problem still existed. I even thought that by upgrading to Lion would resolve any issues that I have with my MBP wireless connectivity issue. After upgrading to buying a new router, new printer and upgrading to Lion; the wireless dropping issue still remains unresolved! I know there are several hundred in not thousands of people who are having the same problem so what are we supposed to do?
When my 1st MBP was replaced in 2010 I had to stop working because I was diagnosed with "Failed Back Surgical Syndrome" and was in the process of applying for disability. Something in the back of my mind said that I needed to purchase Apple Care for this new replacement however I had used all of my savings & retirement to sustain life for me and my family that there was nothing for Apple Care. If it weren't for my church and family I am not sure what I would do during the 18 months of no income while waiting for a decision only to receive an appeal until I findly stood in front of an Administrative Law Judge who heard my case and granted me disability. Besides there was no way I could ask anyone for money to purchase a warranty for a top of the line laptop while the country was falling off an economical cliff.
I broke down and called Apple Support and was told that I qualified for technical assistance regarding the upgrade to Lion a few weeks ago. The tech on the phone had me run some disk utility tests and had me repair permissions which she said could be the cause of the problem. I willingly went along with her in hopes that this was indeed the fix. However, within 10 minutes of hanging up the phone my MBP began to drop it's wireless connection to my new HP printer and also the Internet. Hence my question above is what I am really looking to have answered! What is the fix to this problem that so many people are having issues with? I couldn't afford to purchase Apple Care back in 2010 and I can't afford to purchase a new 2011 machine today if that truly is the fix!
I will be disabled for the remainder of my life and I have grown dependent upon my computer to stay in touch with friends and colleges from work. I worked for the IT Group at Wynn Resorts and I can say that the type of service Appple is providing it's customers is not what I learned over the past 25 years with Mr. Wynn. Why can't Apple get the simple concept that it's customers are it's life line and keeps them in business. I need help and I don't know what to do nor where to turn. It would be different if Apple acknowledged the issue and said they were working on it however they aren't. I plead to Apple to help me fix my notebook so I can stay connected to the outside world vs. couped up inside my home.
Best Regards,
Scott LeavittI am simply lookig for some help not an argument. I am not an RF specialist however have setup a few wireless networks in my tenure at Wynn Resorts. I fully agree that wireless networking is an art and a science however the powers that be in Network Land have toughted wireless networking is the easiest and quickest way to get two computers to talk with one another. As I previously said I have already turned one (1) MBP in for this problem and Apple decided to replace it because they could not fix the problem with my particular MBP. This MBP was running Leopard when the problems started
I am having a hard time believeing that there are several other devicces in my home that depend on a wireless network to operate and my MBP is the only one having an issue. I took this a step further and decided to see what would happen if I tried to connect wirelessly via Fusion. In Windows 7 I am able to print and scan to my hearts content without any issues. I am able to browse the internet as much as I want. I close Fusion and try to connect to my printer via wireless and nothing.
In order to get Apple to help do I need to get a Network Analyzer and capture packets when I have these problems? Out of the 1000 + posts is there a consolidation of which answer is the best? BTW I am accessing the internet via a wireless connection using Fusion and Windows 7.
In response to Linc's comments, I will look at the router specifications however I did not qualify that these devices are not using the wireless connection at the same time. Right now I would guess there are maybe two (2) or three (3) at the most that are actively transmitting / receiving information. -- Thanks -
I cannot get my IPad2 to print (it cannot find the printer) using a Laserjet CP1525nw color printer across a wireless network using a Cisco 1508 Wireless Controller with 49 wireless access points. HELP!!!!

I can get the IPad2 to locate the HP CP1525nw printer without a hitch using a low budget Netgear WAG102 stand alone wireless access point on the same network.If it helps somebody, here is what you need to do.
It worked for me, but only in Multicast-Unicast mode.

In general, the Trustsec design and deployment guides address the specific support for the various features of the 'whole' Cisco TS (and other security) solution frameworks. And then a drill-down (usually the proper links are embedded) to the specifc feature, and then that feature on a given device. TS 2.1 defines the use of ISE or ACS5 as the policy server, and confiugration examples for the platforms will include and refer to them.

I have Macbook Air 13 inch- (mid 2012) with software OS X 10.8.4 (12E55) , i have problem with wireless connection which it drops always, i tried to install windows update 1.0 for (mid 2013) but it not work & gives me message that it isn't support on my system, so now please tell me what the solution to solve this wireless drop.
Back up all data before making any changes.
Step 1
Take all the applicable steps in this support article.
Step 2
If you're running OS X 10.8.4 or later, run Wireless Diagnostics and take the remedial steps suggested in the summary that appears, if any. The program also generates a large file of information about your system, which would be used by Apple Engineering in case of a support incident. Don't post the contents here.
Step 3
If you're not using a wireless keyboard or trackpad, disable Bluetooth by selecting Turn Bluetooth Off from the menu with the Bluetooth icon. If you don't have that menu, open the Bluetooth preference pane in System Preferences and check the box marked Show Bluetooth in menu bar. Test. Continue if you find that Wi-Fi is faster with Bluetooth disabled.
From that same menu, select Open Bluetooth Preferences. If the box labeled Discoverable is checked, uncheck it. Click the Advanced button, and in the sheet that opens, uncheck the top three boxes, if any are checked. Click OK. Enable Bluetooth and test again.
If the application called "Bluetooth Setup Assistant" is running, quit it.
Step 4
This step will erase all your settings in the Network preference pane. Make a note of them before you begin, and recreate them afterwards. It may be helpful to take screenshots of the preference pane.
Triple-click the line below on this page to select it:
/Library/Preferences/SystemConfiguration
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
Reset the System Management Controller.

[SOLVED] Wireless drops out
Hey there,
I have been getting weird problems with my wireless dropping in and out every say 30 secs. I recently did a global update so I am thinking something may have broken.
I also use wicd to manage my wireless connection. Also there is no problem with the wireless itself as another person using the connection is having no problem at all.
Anyone got any ideas on the matter?
Last edited by Rede (2009-12-07 12:14:47)Oh wow, is that a coincidence. My thread in this forum that says Samba disconnects my wifi, I use the same wifi driver, and also use Wicd, and when I try to connect to a Samba share, my wifi starts disconnecting and reconnecting every 10-20 seconds. These problems sound related IMO.

By the above config, we are trying to make the clients to authenticate with username created in the RADIUS which is this router and get an ip address through DHCP pool configured for the same. Will the above config does the same. Kindly let me know.
Thanking You

How to replace the certificate of Cisco 2106 wireless LAN controller for CAPWAP ?
I have interested in CAPWAP feature and I download the open capwap project to make Access Controller (AC) and Wireless Terminal Point (WTP). I had built the AC which used PC and WTP which used Atheros AP. The CAPWAP feature work well when I enabled the CAPWAP that used my own AC and WTP. When I got the Cisco 2106 wireless LAN controller (Cisco WLC), I configured the Cisco WLC to instead my own AC but I got the authorize fail in Cisco WLC side. It seem the Cisco WLC could not recognize the CAPWAP message which sent form my own WTP. I think this issue just need to synchronize the certificate between Cisco WLC and WTP.So I need to replace the Cisco WLC's certificate manually. Does anyone know how to replace the certificate manually with Cisco WLC ?
Best Regards,
AlanUnfortunately this Support Community is for Cisco Small Business & Small Business Pro product offerings. The WLC2106 is a traditional Cisco product. You can find this type of support on the Cisco NetPro Forum for all traditional Cisco products.
