Point to point wireless connectivity

Can I use Cisco AP 1240 for a point to point connectivity of 2 sites having a distance of approx 2 km

If it is outdoor use the following
AIR-BR1310G-A-K9 Aironet 1310 Outdoor AP/Br w/ Integrated Antenna, FCC Config
The integrated antenna will be sufficient for 2 KM Range

Point to point wireless connection

I want to connect an Ipod Touch to an XP Laptop and run VNC remote control sessions.
Can the Touch connect to a computer in peer to peer (point to point) configuration or will it only connect to a network via an an access point?

Hi, Leo :
I don't think it is a duplicate posts ,because my configruration is different , mine is WPA2 with AES-CCM. still has the drop issue.
and I provide more infomation .
thank you .

Is there any way I can control which specific access point I connect (and stay connected) to from amongst a set of access points with the same SSID?

I'm working from a boat in a harbor in which the ISP has deployed numerous access points around the periphery. All the access points share the same SSID and each is configured to use either channel 1, 6 or 11. From my location, there are over a dozen of these access points "visible" (based on the the output of WiFi Scanner) with a range of RSSI and S/N values that vary over time.
The ISP has told me that the quality of my connection should be "perfectly fine" for any access point with an RSSI value better than -75, but I know from experience that my connection quality is miserable (i.e. < 50Kbps download) for almost all of these, including those with RSSI values better than -75. There is at least one exception, however, which gives me on the order of 2Mbps download, which is "great" in this context.
I've tried using a more powerful USB antenna plugged into my MacBook Air (mid 2011), but as far as I can tell, it really doesn't make much difference. Neither does my location within the boat. The overriding factor seems to be which access point I happen to connect up to.
I should point out that the closest access points are about 75 yards away, with many of them being several hundred yards away or more. I'm guessing that even though the signal strength of some of the distant access points is causing them to get "chosen" some times, the results are unacceptable due to the distance.
I'm hoping that I can determine, through experimentation, which access point(s) provide(s) acceptable performance and then configure my Mac to limit my connection to those points through whatever mechanism I need to use (e.g. channel, MAC id, etc.).

Establishing a wireless connection with a client computer is left to the access point for various reasons. One reason that your Mac may not connect to the strongest access point is that it may have reached a limit of the number of clients it can serve, leaving it unable to accept a connection with another. The limit may not be very large.
Suppose that happens, and your Mac establishes a connection with a more distant access point having a weaker signal. Then, suppose a client drops off the network. Doesn't this mean your Mac will switch to the stronger access point? Not necessarily. The throughput delivered to and from your Mac would have to drop below a threshold specified in the AP for it to drop the client, leaving your Mac free to connect with another one. The reason for this is to prevent rapid switching from one AP to another in an area in which two signals are of approximately equal quality. If that were to occur the frequent and repetitive handshaking between the two devices would slow throughput to zero.
In an environment in which several access points are broadcasting the same SSID, Apple provides no insight as to how it determines which access point to choose. This is the reason I suspect this "choice" is a function of the router, or access point. The connection originates with it, not the Mac.
Now, what would solve your dilemma would be to determine a way to control the access point with which your Mac connects, by specifying the access point's unique MAC address for example. In this happy circumstance, you could maintain an editable "whitelist" or "blacklist" of the harbor's access points and be able to choose which among them you prefer.
I do not believe OS X maintains such a record of MAC addresses though, only those of the routers it uses. If I am correct about that, such a solution is unlikely to exist. Don't let that discourage you from searching for one though... I would concentrate on something like "selecting access point by specific MAC address".
I did find this patent application though:
Roaming Network Stations Using A Mac Address Identifier To Select New Access Point
Perhaps it's a start

Point to point wireless using 1310 and 1231 on each site

Hi,
I have an implementation right now with wireless point to point bridging connection. I installed a 1310 with 24 dBi external antenna on one site and a 1231 AP/bridge with 24 dBi antenna on the other site. Has anyone of you tried this set-up. I have no problem with the connection and pinging is ok. However when I tested the throughput I only got 2Mbps in which the distance between the two sites is only 2 kms. I am hoping to have a throughput about 20 Mbps and up.

When you configure the AP radio, you must consider the type of clients that are present in the wireless network. If the AP has an 802.11g radio and the WLAN has only 802.11g clients, you can set one or more data rates to Basic and all other data rates to Enabled However, if you have a mixed environment of both 802.11b and 802.11g clients in a WLAN network, you must ensure that only the rates that 802.11b supports are set to Basic (or Require in GUI). If data rates that the 802.11b radio does not support (such as 12 Mbps) are set to Basic on the AP radio, the 802.11b clients are not able to associate to the AP.
Alternatively, you can configure the AP radio to select data rates on the basis of range or throughput. When you configure the AP radio to select data rates for range, the AP sets the lowest data rate to Basic and the other rates to Enabled. In this way, the AP can cover a wider area. However, the data rate comes down as the distance from the AP to the client increases. If you configure the AP radio for throughput, the AP sets all data rates to Basic. This configuration ensures a consistent throughput throughout the coverage area.

Which outdoor access points to connect two buildings (500ft distance)?

Hello,
We have a client that needs to wirelessly connect two buildings at their location, around 500ft over a parking lot. There are no significant line-of-sight obstructions. Which outdoor access points would be most suitable for this, and what is the maximum speed we can expect from such a connection?
Thanks
Tim

You can configure point-to-point wireless bridging.
Wireless Bridges Point-to-Point Link Configuration Example
http://www.cisco.com/en/US/customer/tech/tk722/tk809/technologies_configuration_example09186a008058f53e.shtml
Next, you can use either indoor access point or outdoor/mesh access point. I'd recommend indoor. Since it's going to be point-to-point, no need to get an AP that can support 802.11n because it's not supported. This brings your choices down to a Cisco 1242 (dual radios).
In regards to antennaes, AIR-ANT2410Y is a contender. Have a look at the complete portfolio for more information.

3502p AccessPoint support MESH and Point-to-Point Wireless Bridging with Outdoor Antennas??

I need to know if 3502p with outdoor antennas supports Point-to-Point Wireless Bridging??

The 3502p is only used for arenas and or stadiums. These are different units than the 3500's and 3600's. So no they can't be.
You can use Cisco Aironet 1400 Series Wireless Bridge for a wireless link between two buildings (1km) to extend your LAN. For more detail you can go through the below link.

Firewall necessary for Point to Point internet connections?

Firewall necessary for Point to Point internet connections? We have multiple point to point t1 connections to our sites and was wondering if a firewall should be in place to filter traffic. We are also implenting a microwave t1 from a service provider and was wondering if firewalls would be needed for just this or the wired as well. According to the microwave company no firewalls are needed. Do i really want to leave security in the hands of the ISP?

Matt,
If you are buying private line T1 service from a carrier that connects 2 of your sites you would not use a firewall. Your traffic is never mixed with any other traffic. If your data is very sensitive, or if you have to comply with Payment Card Industry standards then you might want to encrypt your data, but a firewall would still not be necessary.
If you have a T1 connecting you to the Internet for Web browsing etc then you very much do need a firewall.

Define access point to connect?

A couple of applications on my phone, particularly Ovi Maps keep doing this and it's getting REALLY annoying.
Start using the application, it comes up with the following:
"Network connection required.Define access point to connect?
Then it'll give me a selection from a list of my networks various protocols.
It will regularly ask me again and again while the app is running, often coming up in front of other applications i am using at the time!
How can I stop this?
I don't want to have to define anything for specific applications. I want my phone to connect in one of two ways without my input:
1. If I am within range of a Wifi connection it knows, connect via that.
2. If not, connect via 'O2 Active'
Is there a way I can set this so my phone just does the above and never asks again?

It is the Assisted GPS positioning method access found in Menu > Settings > Application Settings > Positioning > Positioning server use which keeps asking for a Network access point not OVI Maps application itself which may be set "Offline" or "Online".
If you have not set "Save location info" = No - in Camera > Options > Settings - you may get the same response.

Point-to-point SSL connection

Hi all
In my project, I need to use SSL, however, there is a server at the middle that connects to the Internet and I want to make a point-to-point SSL connection with the Internet client through that middle server. The following is the network configuration of the system.
Server A is the server that proccesses the data and it has no internet connection.
Server B is connected with Server A with a leased line and it has internet connection, so that client with Internet access can connect to it.
Client uses the Internet and connects to Server A through Server B.
Now I want to know if it is possible that Client can make a point-to-point SSL connection to Server A because I don't want my data to be decrypted by Server B.
Thank you !
Edmond

(My remarks might be entirely beside the point. Nevertheless.)
Here a Web Service seems appropiate; Sun has its SDK, IBM offers things also, etcetera.
The advantage of a web service, is that inside the message envelope several parts can have different encryption. Just for these kind of indirect tunneling web services are meant. In fact "web" is just a buzz word, communication by email is just an option too.
However I hope, that someone else might have a more direct solution.

Single point of Connection?

Hi Experts,
Major advantage of XI and other middleware technologies is ..
XI is a single point of connection.

Hey
it is possible to handle parallel messages in IE.but i guess you are looking for message processing in general.
see all the messages are processed in the order they arrived ,you have the option of prioritizing the messages in IE meaning you can give a higher priority to some important messages but this prioritizing is not possible at the adapter engine level,so adapter will pick the messages in the order they arrived,now when they enter IE and you have set the priority for them then they are processed based upon that,if no priority has been set they are processed in the order they were received
Thanx

I get wireless connection but my internet does not work on my ipad 2

I get wireless connection but my internet does not work on my ipad 2

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Wireless connection not working after installed newest Lenovo ThinkVantage System Update programs

Hi, everyone!
I've installed some newest programs through Lenovo ThinkVantage System Update and just after that my wireless connection has stopped working. Here are the installed programs:
ThinkPad UltraNav Driver for Windows 32-bit version 15.0.24.0;
ThinkPad Power Management Driver version 1.60;
ThinkPad Modem Adapter version 7.80.8.0;
ThinkPad Hotkey Features Integration Package Setup version 3.11.0001;
Inter Wireless WiFi Link for Window XP version 13.02.0000;
ThinkVantage Access Connections for Windows XP version 5.62;
ThinkPad Power Manager version 1.88;
Lenovo ThinkVantage Toolbox (32-bit) version 6.0.5514.61.
I've got a Lenovo T61 with Windows XP SP3.
Also in Device Manager, there are now the two "Other devices" bellow with a yellow question point and a yellow exclamation point by side:
Bluetooth Hands-free Audio;
Bluetooth LAN Access Server Driver.
Does anyone have any idea what can be done to have these issues solved?
P.S.: when I click Fn+F5 it shows only the Bluetooth Radio.

Hello and welcome,
I've seen something like this on XP machines after updates a couple of times now - my T61, a friend's T400, and his daughter's T61. I guess that makes 3
_Maybe_ your situation is the same.
The fix in all 3 cases was to go to device manager and uninstall the wifi driver. Then scan for hardware changes and let it reinstall the driver. Something about how Access Connections or some other networking mangement thingy was hooking the drivers I guess.
On both of the friend's machines, the wired networking was also b0rked. Same fix there.

PhotoSmart 310a doesn't print using wireless connection

First... I have to say that if I had known what a HUGE pain in the butt this printer was I would never have bought it. On top of that, the thing apparently doesn't have an option to "hard wire" connect it to my computer... which the guy at the store didn't bother to point out. On top of that HP's customer service is, apparently, non-existent, as attempts to reach by phone are useless.
They can't even seem to get the model number on the machine where you can find it... so the instructions on "how to find your model number" are useless.
That said... here is my problem... which if I can't fix, I'm simply returning this and getting something else.
I have my printer all set up. Wireless is set up. ePrint is set up. Test pages print fine.
I have actually been successful printing with it ONE time.... so I know that it can do it.
It does give me a "low signal" message - however it seems to have no problem printing using the email option, or downloading from the web for the "reports." It scans and my laptop "sees" the scanned image, which is transmitted over the wireless network. If it is truly a low signal problem it seems like it would have issues with other functions regarding the internet.
BUT... when I send something from my laptop (MacBook OSX 10.5.8) to the printer it says...
.. connecting
.. idle
.. priinting (%)
.. then the print job disappears from the queue in the dialog box ... yet nothing actually prints out.
.. it then say's "Printer Ready" - I guess ready for another print job that it won't perform.
.. It does NOT give any kind of error code... say it's "paused" or anything like that. It's as if it THINKS it is printing... but it does not. It makes no sound like it's trying to print either. Paper is loaded in fine and it will print test pages with no problem and doesn't indicate any problems on those other than "low signal"
... When I use the "printer utility" to print a test page - also goes wireless - it prints just fine.
I've tried to use this printer only 4 times now for various jobs... and each time has been an ordeal lasting from 30 minutes to several hours. I've managed to get it to print on one occasion... though I can not remember how I did it.
It has NO problem printing from an email... so I guess I could just always do it that way... but it involves several extra steps to do so and I'm not even sure it would work for every type of print job I need.
It works fine scanning
It works fine photocoping
It works fine printing from ePrint (email)
It just DOES not print via the wireless connection
I don't understand how a company can make something this sophisticated and not have it give you an ERROR CODE when it fails to complete a function... and frankly, I'm fed up with this thing. It's a big, oversized, shiny paperweight and I've wasted way too much of my time trying to figure it out. This is one last ditch effort.
Can anyone help? THANKS so much if you can!
Sue

It is more likely a network problem, so please tell me about your network - router brand/model, encryption type (WEP, WPA, etc) and ISP type (DSL, Cable, etc).
In the mean time, you could try this quick trick; resetting the printing system:
- Sys Prefs, Print & Fax
- Right (control) click in the rectangle listing your printers and select Reset Printing System.
WARNING - this will delete ALL of your printers!
- Select the plus sign to re-add it. Look for the printer, select it and wait until the "Add" button becomes available. Click it.
Oh, and indeed this printer does have a USB port for connection directly to your computer. It does NOT have an Ethernet port for connection directly to your router.
Say thanks by clicking "Kudos" "thumbs up" in the post that helped you.

Not the average problem with wireless connection. Please help me..

I've been having wireless connection problems ever since I upgraded to Verizon FiOS from Verizon Wireless. Before upgrading to Verizon FiOS in the fall of 2012, my brother's laptop connected just fine with the connection. After upgrading to Verizon FiOS, my brother's laptop could not connect to the internet. It showed the wireless connection signal as Excellent, but I could not access the internet. Either it would be extremely slow or there would be no connection at all. Also, the router would sometimes restart itself randomly, and it was extremely annoying for me since I am hardwired with my desktop.
This was weird because my iPod Touch connected perfectly fine to the wifi. So I thought it must be the laptop. But I brought the laptop over to my cousin's house, who also happens to have Verizon FiOS, and the laptop connected perfectly fine. I called Verizon and none of the technicians knew what the problem was. We tried disabling and enabling the router, changing the channels, and anything that was on the list. They couldn't help me and I was extremely disappointed because not only am I not accessing the internet with my brother's laptop, but I am also paying for the service too. The last technician I called in 2012 decided to send me a new router. I hoped this would work, but it did not. This router, too, would completely reset itself numerous times before settling down and letting me use the internet.
I gave up after that. But in the spring of 2013, I got really fed up with the service I was receiving and I decided to call Verizon again. Again, Verizon tried to help me fix the laptop with their tools and solution guides. But nothing good came out of it, so I decided to ask for a technician to come to my apartment to fix it. We scheduled a day and I was pretty excited since I was almost positive that the connection for the laptop would be fine by then.
I was wrong. The technician came and only stayed for about 20 minutes. He said it must be the laptop or it must be that the walls are too thick in my apartment. But that can't be it since, in my cousin's house, the router is on the second floor and my brother was using his laptop on the first floor. So it couldn't be the laptop nor the house. So we came to no conclusion. He just attached a mini router to the laptop and hardwired it. I wasn't so content but I was glad my brother could finally use the internet now.
About three months pass by and I decide to get myself a new laptop. I get it and I am hoping the wireless connection works. It did, so I was almost positive that it was my brother's laptop that was the problem, not the wireless signal. I go on vacation for a few days and I connect perfectly fine at my friend's house. When I return home and try to connect to my wireless connection, it didn't work!
At this point, I am extremely frustrated. I decided to call Verizon again to replace my router because it was being extremely annoying. It kept resetting itself and I was tired of it. I replaced the router, and this is the router I currently have, but I STILL have the same problem. It resets itself on its own time and I hate it because I'm always in the middle of something. Wow, just wow. There is nothing they could do to help me fix this. I call up a technician, for the millionth time, and he tells me he can't access my router. This occurred with the previous technician who sent me the new router. He tells me his tools are not working and tells me he'll call me back the next day.
It was the next day and I did not receive any phone call. I am extremely disappointed in Verizon FiOS' service and it's customer service. I leave it alone and I just hardwire my laptop to the router. Of course this works, but what's the point of having a laptop when I have to keep it hardwired on my desk? After a day or two, I decide to check if the wireless connection works, and it did. I was surprised. But every now and then, it would shift on and off. Most of the time, the wireless connection is either EXREMELY SLOW or I get none at all, nonetheless, it still says the connection is Excellent.
Please, if there is anyone who could help or try to help me, I would most appreciate it. If there is more information that you need, ask me and I will try my best to provide it to you.

Admittedly, that IS a strange case. Unfortunately, it sounds like all possible troubleshooting has been done by the tech support agents. you mentioned that you were dissatisfied with your other service, did it have a similar problem? theres a possibility of dirty fiber or a bad ONT port, but the random rebooting of the router would almost exclusively be a bad router. question: is the router in the same location as before?
