Aironet 1260 and external Antenna

I know you can put a minimum of 3 AIR-ANT-2422 antenna on the 1261 AP but my question is, can you mix and match antenna?
Currently there is an AIR-ANT-24120 used on an older 1200 model. Upgrading to a 1261. The 24120 is 12db and 2422 is 2.4db.
Environment is Manufacturing floor with 30' ceilings, worried about coverage. Can the 24120 work on the 1261 or am I stuck with the 2422s?
Thanks

You can't mix-and-match these two. AIR-ANT-24120 is a 12 dBi antenna. The 1260 will not support anything higher than 6 dBi because this model simply doesn't have enough power to do so.
The 1260, 3500e and 3600e doesn't have enough power because in the past people kept complaining that the 1250 needed 20.0w PoE power. Now the the 1250 doesn't have any limitation about the maximum (maybe it does but I haven't seen or heard of it) gain support. So Cisco cranked down the power requirement of the new WAPs and balanced it to the antenna gain.

Nokia 3315 with cradle and external antenna(car an...

I have an old 3315 and I use it on a boat with an external antenna to get a better calling range.
My old 3315 is now having repair problems and I want to buy (on eBay) a more modern phone but still use the cradle and external antenna. A problem with the 3315 is that they are becoming uncommon and the ones that are available have been well used and often have tech problems now.
I see that the 3310 has a similar shape and no doubt the cradle fits it also. I have the antenna on a long piece of coax cable and pull it up the mast on the sailboat to improve the reception.
Can anyone give me some help with this? The more modern I go the more features I get (eg mp3 player,radio reception) however I still want to retain the existing external antenna setup as it is great for camping and boating to stay in touch.
Thanks
Peter

Also, what is the length of the cable, and what is the model No of the cradle?
I have a 3310 and can test how well it works with your setup.

Two TNC connectors on Aironet 1310 for external antennas

Hi All,
I have been checking the "Cisco Systems Aironet 1310 Intallation" manuals, and have noticed that the external antenna model has connectors for two antennas.
My question is if this device could be used as repetitor (logically splitting the signal between the two antennas)?
I will appreciate any comments.
Best Regards,
Igor Sotelo.

Although you can't fit two antenna to service two connections you might be able to get it to work with a single omni on the "relay" station so it can "see" both the remote stations. I've used this setup before and sometimes you can route traffic end to end, sometimes not. A certain solution would be 2 x 1310 at the central point connected with a cross lead. That way you are running two separate bridge connections and everything will work just fine, needs another bridge though : (

Problem on Cisco AP 1240AG and External Antenna

Hi all :
I am setting and configure the Cisco AP 1240AG with 5GHz External Antenna extension. The whole product is called iWap. The problem now is that the wireless signal amplitude only can reach 3 bars instaed of ful 5 bars.
Please help below few questions I have for this setup and configuration :
1. What is the default or original frequency of antenna of Cisco AP1240AG? Can a 5GHz antenna work with the AP 1240AG whereby it is run with 802.11a and 802.11g?
2. If 5GHz antenna can work with 802.11a or 802.11g, what is the setting or configuration needed to be done at the Cisco 1240AG? Or, no setting or configuration needed because it will automatically work by default?
Many Thanks in advance and best regards,
tangsuan

1240 is the product "line," 1242 is the specific model. The come in both G and AG variants. The link below is a picture of an AG variant (with both an 2.4 Ghz "A" radio and a 5 Ghz "G" radio). The two antenna ports on the top in the blow image are for the 5 Ghz radio, and there should be some blue text indicating as much.

If you don't have the two antenna ports on top, and just have two near the ethernet and console ports, then you have a "G" model, which only have a 2.4 Ghz radio. See my pic below. G model on the left, AG on the right.

Bridge and external Antennas

I am trying to setup 2 1240ap in a bridge mode using external antennas. I am wonder how you line up the antennas to obtain the best signal. I know the 1300 series has software that allows you to see a signal as you line up the antennas, but I don't think the 1240 series has that feature. Any help would be greatly appreciated

There's a couple things.
You could hook up a laptop at the receiving end and attach a directional antenna to the wireless card. Then use something like netstumbler to position everything where you want it.
I guess you could also use a laser pointer. Mount it on the top of the antenna in question, and target the receiving antenna. Obviously, have the minion you're using on the other side face AWAY from the laser pointer. ;)

Car Cradle for Charging and External Antenna Compatible with Tour

Is there a car kit that allows easy charging and connection to external antenna for the Tour? I had Comfort Cradles by Bury for my last two BlackBerrys, but I just was disappointed to learn that Bury does not have or even plan one for the Tour. Any suggestions? If I had known this before, I probably would have stayed with my 8830. Thanks.

To answer my own query - I just spoke to someone at Smoothtalker and was informed that Smoothtalker will be releasing a charging cradle, with external antenna conttection, for the "Tour" in "about a month."
I still would be interested in hearing from anyone else with any information concerning this.
Thank you,.

Mac mini: WiFi Board Manufacturer and External Antenna Capability

I recently purchased a new Mac mini and plan to run Linux Red Hat Fedora Core 4 on it (erasing OS-X, as it will be a dedicated Linux ap). My particular application requires that I run WiFi. I don't know if Fedora Core 4 running on a Mac mini supports the particular WiFi manuafacturer's internal WiFi card that Apple is using in the current Mac mini.
2 Questions:
1. Does anyone know the name of the Manufacturer, and perhaps the Model Number, of the internal WiFi board in the current Mac mini?
2. Has anyone opened up a Mac mini to see if the internal WiFi card has a standard SMA type connector to the antenna cable so I can utilize an external gain antenna for longer range WiFi?
Thanks, in advance, for any help on this!

Yes, but I don't think that will do the trick. My application involves supporting a gateway for the ICOM D-STAR digital voice and data Ham radio repeater system. The computer (running Fedora) must have 2 Ethernet ports (note: a USB interface supplying a second ethernet connection is unacceptable due to latency concerns). The only way to do this is to use the Mac mini's single (only!) Ethernet port to interface to the ICOM gear. Since you can not add a second Ehternet port to the Mac mini (unless you use a USB adaptor which has unacceptable latency for this ICOM app), you must therefore use the Mac mini's internal WiFi board to connect to the Internet. The problem is that I don't think Linux Fedora 4 supports any drivers for the Airport Extreme card.
I saw on the Internet late yesterday a blurb saying that all of the Macs use the Broadcom WiFi card, and it has not released its drivers. Apparently, there are a few preliminary drivers for the Airport Extreme card on Fedora 5 (in the very early experimental stage), but these are preliminary and based on soemone's reverse engineering, which is always suspect, at best.
However, I don't know if Apple has possdibly switched vendors for the internal WiFi board in the latest Mac mini, since they now have a new unified board that supports both BT and WiFi on the same board/chip. My fingers are crossed that maybe they are NOT using Broadcom on the latest Intel Mac mini?

The 1310's either have an external antenna connector or an integrated antenna. They don't have both.
The part number AIR-BR1310G-x-K9-R requires and external antenna. AIR-BR1310G-x-K9 has the integrated antenna.

Make SSID Hidden Aironet 1260

We have three Access Points, two Cisco Aironet 1260 and one 1240AG. Originally, the SSID was hidden on all three AP's and users had to go to Other Networks and type in the SSID and password to access the WAN. About a few months ago, the network started broadcasting to the public. I am trying to make the SSID hidden again, any suggestions? I have tried going to the Security tab, choosing the SSID Manager and setting single guest mode to none but it has not helped. Any suggestions? I have researched this a lot. If you are confused on my situation ask me questions.
Michael

Amjad,
The SSID is based on the company I work for so I think it is safe to rule out other people with the same SSID. We are in a building with a few companies.
I did not get a chance to try your method yet because the AP's are hanging from the ceiling and I think I need to download something to change the CLI. I manage at the AP configs off of their IP addresses all the time.
I got the SSID to remain hidden now which forces me to connect to it through other networks and knowing the SSID in advance. This what I was trying to figure out. Here's what I changed.
On the http AP interface I clicked Security, SSIA Manager, then I went down to Client Authentication Key Management and changed WPA to WPAv2.
I had the encryption set to WPA2 on two of the AP's but the third one is an older model and only can do WPA. Hopefully, I finally fixed this.

When I use a GSI external antenna for WiFi I first get a message that "Firefox is already running but not responding etc", and then Firefox crashes. Can anyone help please?

Because of weak WiFi signal I need to use an external antenna (GSI USB wireless WIFI long range network adapter). My computer can see the signal clearly and shows that I am connected to the right network. But when I try to launch Firefox I get a message that "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system." When I click "OK" Firefox tries to load websites but gives up and reports "Problem Loading". It looks like Firefox is having trouble "seeing" the signal from the external antenna. What do I need to do please?

Try Ubuntu support, I don't think your problem is with Firefox - it will use the connection that the Operating System "makes". I'm a real noob with Ubuntu myself, and don't think I can help you figure out the problem.

WAP200E and WAP200 as repeaters, external antennas, poor signal

I am having some weird things happen...
I have setup a WAP200E external w/o optional antenna and using (2) WAP200 internal units in separate buildings setup as repeaters. I have added a external
Yagi 10Dbi directional antenna to both repeaters with short cables and using the standard antenna for the internal wireless needs.
Both buildings are about 200' line of sight from the WAP200E with a angle of less then 45 degrees from the WAP200E,
I am getting a signal that continually jumps from 20% - 60% Channel keep changing etc... looks like a typically poor signal connection
I am able to access the internet from either repeater, but not reliably
Question 1: External Antenna....
I was going to install a similar external Yagi antenna on WAP200E but I was reading that the external antenna in turned on automatically when the WAP200E
senses a antenna. Cisco only certifies one particular antenna to connect to the WAP200E and that is the HGA9N which is a 9DBI omni directional antenna
I would much rather use a directional antenna, but I was reading that the WAP200E may not reconize any other antenna's, plus I cant find any way to determine if the WAP200E actually turns on the external antenna. Does anyone have any experience using the WAP200E with external antennas?
Question 2:
SSID's on repeaters
On the WAP200E and WAP200 units, It show that that repeaters can have unique SSID's I tested them using the same SSID as the A/P and also with unique SSID's Which approach would be the more reliable?
Question 3:
Freq Channels setting:
Typically I would set the channel to be fixed on all three units to keep them from hopping from channel to channel. Is my logic correct?
Is there any way to determine which channel is the best, beside trial and error?
Also, can I lock the speed to a slower setting to help improve reliability?
Question 4:
Bridging:
I was considering setting up one of the repeaters as a bridge can the WAP200E A/P handle communicating with a bridge and a repeater at the same time?
Does anyone have any experience using these as bridges? I see a few issues online regarding briging with these units
Wireless is tough enough, but flakey wireless product can make you wish had a wire
Firmware... 1.20 on the WAP200E A/P unit.. I guess I will try 1.20a but the blogs say it doesnt matter
Firmware on the WAP200 unit is unknown at the moment
Thanks in advance

Update...
After speaking with Linksys support staff, they informed me that the antenna jacks on the WAP200 are slightly different
One jack is TX & RX and the other jack is RX only...
It is not documented or labeled as such on the device.
The support person told me it was the right jack when facing the rear of the unit with the network jack facing you. but this is the way I
had it configured... so for giggles I swapped the antenna jacks and presto it works fine
Many thanks
Bob

Airport express external antenna and socket.

Hi Everyone - I'm new to this, so please excuse me if my question is naive.
I have a fault with my airport extreme card, which I believe I've narrowed down to either the external antenna or the socket it plugs into on the rear panel. I know I can replace the antenna, but can anyone help with the rear antenna socket - is it possible to replace this and, if so, where could I get one from?
I would be most grateful for any advice.

It is possible to replace the antenna board. AppleComponents.com has the parts, but you'll need to be careful to select the correct computer. Your signature states that you have a dual 2.0, but there were three different 2.0 DP machines. The part is not common amongst all of the models.
The install is not the easiest either. It will require you to remove the upper processor and a few other components. If you remove a processor, you'll need to run the thermal recalibration routine from the service discs. This is true even if you reinstall the processor in the same socket. An Apple Authorized Service Provider will have this disc, or you can locate it yourself with enough searching.

External antennas and gain settings

Cisco AIR-AP1242AG-E-K9.
In the web interface, if one goes to:
Network Interfaces/Radio0-802.11G/Setting tab
half way down the page there's a section called External Antenna Configuration and you can enter an Antenna Gain in the box.
The access point came originally with two small plastic antennas, about 6 inches long but I took these off and connected two external antennas, one is 3db, the other 6db. Should I enter 6db in the box or does the access point set the gain automatically? At the moment all antenna settings are at default.

In the case of a Dish, yes, it would absolutely impact your throughput.
It would be better to put the dish on one port and disable the other port.
The dual ports are for diversity; in an inside environment, having two antennas a small distance apart reduces the effects of "multipath" and "nulls" ... multipath is when there are several images of the same transmission (from multiple reflections), nulls occur when you combine a series of waves (like a primary wave and a near reflection) and the combined waves, added together, result a greatly diminished signal (like a "plus" 35 meeting a "minus" 35 ... the result is a null, or no signal).
For point-to-point, or point-to-multipoint diversity is generally not desired or needed.
The way the antennas are used does not permit efficient operation for coverage of more than one specific area.
Good Luck
Scott

Aironet 1250 and AIR-ANT2430V-R

Hello,
I've just installed a Aironet 1250 and AIR-ANT2430V-R antenna.
I could do with some pointers on configuring the 2.4Ghz radio interface.
Role: Access Point
Goal: Blanket office coverage
Channel width: 20Mhz or 40+ ?
External Antenna Configuration: Enable
Gain: ??db
Currently I'm seeing speeds between 1Mbps and 144Mbps, with sporadic coverage.
I was expecting Â£900+ equipment to be better than the Â£10 D-link POE WAP currently installed! =]
Thank you in advance
K

Do you have the rp-tnc connectors fastened tightly?
How are you measuring the bitrate?
Also, have you tried using a tool such as iperf to measure actual throughput and not bitrate?
If you are running 802.11n rates on the 2.4 spectrum and plan to deploy more APs on the network, you will want to stay away from channel bonding.
We do not run 802.11n on the 2.4 side, only the 5Ghz side.
