Increasing CIsco 1200 AP Throughput

Hi,
I'm having a problem achieving good performance on a Cisco 1200 AP [802.11b] which supports about 15 clients. It's been configured to allow only 11MB & 5.5MB access with static WEP & w/o SSID broadcast. But somehow the performance is way below satisfactory & it took about half an hour just to copy a 500MB file between 2 computers. Is there anything that i may had missed out during the configuration? Please advice, Thanks!

Check the 1200 error counters (under radio interface Detailed stats) and see if CRC errors are increasing in huge amounts. If yes, this could be a cause for the slow down. You might be experiencing interference. Did you do a site survey (including scanning the surrounding for interference) before installing the AP.

Cisco 1200 as bridge

Hi everyone
I am about to use Cisco 1200 series AP as bridge , but I have seen and I have compared it with Cisco 1300 and 1400 outdoor models , and I saw that 1200 is mainly for indoor (LW).
Now the question is :
1. Can I use it as outdoor bridge for Point to Point linking ?
2. What will be maximum distance with reflector grid antennas (and patch antennas)?
3. If in practice , is it stabile ?
Thank you

Again I stress I can only go by what I'd install in the UK so it may not be applicable wherever you are! Also, I always try and avoid mixing vendors equipment if at all possible so I would use either one of two Cisco antenna, I've also listed antenna cables, use the shortest you can:
AIR-ANT1949 Yagi mast mount 2MB at 29.49 km.
AIR-ANT3338 Solid Dish 2MB at 42.62 km.
AIR-CAB020LL-R 6m antenna cable 1.3db loss
AIR-CAB050LL-R 15m antenna cable 3.4db loss
AIR-CAB100ULL-R 30m antenna cable 4.4db loss
Ranges and throughputs are Cisco's, you may find the biggest problem is clear line of sight over that sort of distance.
For more information check the antenna guide here:

You can have this one free of charge : ) just don't forget to award points if it's of use : )

The maximum cable distance from antenna and Cisco 1200 series.

Hello all!
I?m using the Cisco 1200 Access Points Series with two 2.2dBi dipole antennas. I have read the installation guide for that Access Points and that can be installed with the antennas in separated places. But this guide didn't mention the maximum distance for the antenna cable...
Somebody here can say me this maximum distance?
Had somebody here made this kind of antenna installation with cable?
Thanks.

Oh Yeah!, I absolutely agree on "shorter is way better"
Given any chance / choice at all, I'd try to keep the cable length under 25 feet. If the option is available for a NEMA cabinet to get the cable shorter, I'd probably do that too.
Since it's good practice to use a chunk of fiber optic cabling between the external stuff and the inside network, you may as well put the AP as close to the antennas as possible and convert the copper to fiber for the long haul.
You get some lightning protection (at least you won't smoke all of the systems sitting on your LAN) and better signal strength (and probably signal quality too).
For something like a 200' run, if forced to do it (we're talking "gun to the head" forced here), I'd probably be looking for something like Andrew LDF4-50 1/2" Heliax with probably a weeeeee bit O' amp tossed in for good measure.
That would also imply that the system would also have to be re-certified, because of the non-standard components ...and a pretty good budget to boot.
Sometimes you gotta do what you gotta do.

Increasing the File Copy Throughput

How do I increase the file copy throughput (within and between the Azure VMs)?
I have read the article about increasing the number of ServicePointManager.DefaultConnectionLimit but couldn't find how/where I can make this change.
http://blogs.microsoft.co.il/applisec/2012/01/04/windows-azure-benchmarks-part-1-blobs-read-throughput/
Currently, when I make copy the file between the VMs or Drives within a VM, the transfer speed is only 10-20 MB/s and I think it should be much higher than this especially when I am copying between the drives in a VM.

HI;
Please create a new VM from a different storage account in a different geographic location and cross check.
in case if the issue still persists we will need to further investigate it and you would have to open up a Technical Ticket with our Windows Azure Technical Support team.

Cisco 1200 Access Points as Bridges - Won't work

I could use some help. I have a pair of Cisco 1200 AP's that I'm trying to use as bridges.
I have selected one as a Root Bridge, the other as Non-Root. The non-root shows the wireless interface down and the log reveals 'no association'.
I have verified NO security, identical SSID's, broadcast SSID, no encryption, no WEP, they are sitting 10 feet apart, same channels, etc. etc.
Can a 1200 access point serve as a bridge?

I went to Security > SSID Manager and selected the only SSID as the infrastructure SSID and it did nothing. If there is another place to toggle 'Infrastructure SSID' on and off other than by assigning one, I'm unaware of it.
Any other ideas?
Thanks.

Cisco 1200 on long distances

I need to know (if anyone have in practice). What will be maximal distance in ideal conditions with Cisco 1200 series AP for outdoor point-to-point connections in WGB mode with high gain directional antennas ?

Console into the AP and post the log. This will help understand the issue better.

Cisco 1200 empty .csv file

I have flashed the cisco 1200 ap using the upgrade utility. Everything checks out ok but the .csv file is empty.Did i miss something here?
Details
Model:AIR-AP1232AG-S-K9
Autonomous IOS:12.3(7)JA2
Lightweight IOS:
c1200-rcvk9w8-tar.123-11JX1

The MIC is a Machine Installed Certificate. The AP has the certificate already installed, there is no need to
generate a self-signed certificate. That is why the .csv file is empty. You will not have to put any certificate information on WLC/WCS for this AP.

Wireless client can't get an IP but can associate with the Cisco 1200 AP

Hi!
Good day to everyone.
I guess i need some help with regards to a problem of mine.
I have a Cisco 1200 AP with IOS 12.3(2), the client is MS Win XP on an IBM notebook with an onboard intel wireless client.
the RADIUS server is a MS IAS and it is integrated with MS Active directory where I authenticate.
somehow the client can associate with WPA and TKIP however it won't receive an IP add after logging into domain. I have tried clearing out the TKIP and WPA and leave authentication open and guest mode on the config. this would be successful.
I also want to ask what does the "list_name" on the methods of authentication on EAP? Is this a RADIUS server's name or the AD server's name?
Attach is the configuration I made on the AP.
Thanks in advance,
Chris

I have this same issue, it seems the AP is not supplying the group key needed to complete the authentiction...so your being authenticated, but not fully with the AP. I have a sniffer of a good connect and a bad one, its got something to do with the key (if you look at the link status, you will probably see something like this beside security
TKIP, WEP, Key Absent
The Key Absent portion is bad. Its whats stopping us from getting fully "connected" with our AP's, but i have yet to figure out why.

Cisco 1200 series upgrade failure

I might have an answer for you... or I might be COMPLETELY WRONG
If it isn't just a "failed" upgrade, as in you've tried the upgrade again and it still is happening.... I was reading something about older APs not have a Manufacturing-installed certificate (MIC) and these AP's generating a Self-signed Certificate (SSC).
The error you have is referring to SSC so I'm writing this as if you have not had to previously do this step for your other conversions.
I believe a couple of things needs to happen for SSC AP's.
1) Must enable controller to accept self-signed certificated.
Security > AAA > AP Polices > Accept Self Signed Certificate > Apply
2) Add AP to Authorization List in Security > AAA > AP Polices > Add AP To Authrorization List
Enter MAC Address of the AP
Certificate type = SSC
SHA1 Key Hash can be obtained from the controller by issueing this command:
"debug pm pki enable"
Look for the line: sshpmGetIssuerHandles: SSC Key Hash is XXXXXXXXXXXXXXXXXXXXXXXXXX
I believe you use the XXXXXXXXXXXXXXXXXXXXX as the SHA1 Key Hash.
3) If required, you may also need to add the AP MAC Address in the Mac-Filter: Security > AAA > MAC Filtering > New >
Hopefully its either a reload of the software or this SSC thing that fixes the problem....

Cisco 3945E Maximum Throughput Potential

Hi,
Am looking at purchasing a router that is capable of serving a WAN bearer at up to 1Gbps. The 3945E has had good reviews as a high throughput router but the datasheets suggests performance of 350Mbps. It also states that additional performance can be ensured by adding SPE modules. Does anyone know whether the 3945E could achieve up to 1Gbps with SPE modules?
If the 3945E can't achieve such performance, I would appreciate alternative model suggestions. The key features I am after are:
IPV4 and IPV6 support
L2tpV3 support
BGP
IP SLA
1Gb Copper Connections on-board with capability of at least 4 Ports
Regards
Mike

Have you looked at the new 4451-X ISR?
Supposedly the same pricing as the 3945E, but with 1-2gpbs+ performance.
Also with very low impact when turning on features in comparision with the older ISR routers.
I saw a presentation about it on Cisco Live Virtual.
Edit: Sigh.. replying to a necro thread. :(

Cisco 1200 Access Points

Hi,
Is it possible to setup an Aironet 1200 in Root AP mode, where it does DHCP for the Wifi clients and NAT. Where the wired interface is equipped with a public IP?

If your 1200 has two radios, yes. Otherwise it's either a root or an AP but can't be both (per radio).

Cisco 871 and throughput with QOS

Considering an 871 to carry out CBWFQ on circa 4Mbits of bandwidth allocated by a provider.
Will the platform handle that sort of throughput? Any experiences?

Thanks Paresh,
Had never encountered that guide before - certainly useful.
I still wonder whether anyone has experience of the throughput that can be achieved with QOS features enabled such as a CBWFQ applied to 4Mbps. I doubt such a figure will exist in the literature, it would probably have to be a field measurement. Has anyone got any such field measurements - especially with the 871 but also with any other SMB platform.

Make cisco 1200 assign a static IP not DHCP

I have given the airport an IP address and installed the card in my laptop. I can connect as far as the airport and it shows me as being connected, but the IP address it assigns isn't configured to go through our router.
Unfortunately the router is managed by another a company and I am unable to change the routing table....so is there anyway you can set the airport to assign a static IP or assign from a range of IP's.
I've looked through the manuals and on this site without any sucess, any help anyone can give me would be great.
Regards
Rob

Just to add some more....Since cisco's AP can't work like/as DHCP server, it can't assign static/dynamic ip addresses to the wireless clients..So in your case you need fix the router to do routing for your ip address or fix it accordingly..Tejal

Cisco 881 max throughput

Hi, I need to provide a router to connect Internet circuit and run IPsec to MPLS network. Circuit is 10Mbps.
What is the max a Cisco 881 can handle if running IPsec?
Also, if you are aware of any branch router (1941) which allows connection to future 4G LTE please let me know.
