1310 Bridge RG-59 coax cables.

Hello all, hope everyone is well.
The RG-59 coax cables that come with the 1310 bridge are only 1 foot long. Does anyone know where I could get longer cables as the power injector is quite a distance away because there are no close power sockets. Instead of installing new power sockets near to the bridge, we wanted to simply run longer coax cables.
Hope someone can help!

This cable is standard CATV (cable/dish antenna cable) type RG-6 that is commonly available at any radio or entertainment store - It is exactly the same cable that is used to go from the cable TV receiver to the television - Raw cable and connectors are available from places like Home Depot, Lowes, Walmart etc.

Aironet 1310, power injector and poe cable

Hello,
Can the power injector delivered with aironet 1310 be supplied by a PoE RJ45 cable rather than the traditionnel DC adapter?
The problem is, i thought Aironet 1310 was PoE. Which means it can be power supplied by a rj45 cable.
But, when i openned my brand new 1310 box, i realized that 1st, it needs that Power Injector to work and that 2nd, Power injector needs a power supply...
Usually when i buy a PoE access point, I just plug in my PoE rj45 cable and its power supplied :)
Anyway, i hope there's an issue for this because where the 1310 should be placed, there's only a PoE rj45 cable arriving.
Thanks in advance,
lachapelle

Hi lachapelle,
Sadly the 1310 cannot be powered by PoE ,but, the Power Injector can be up to 100 meters away from the unit.
Dual coaxial cable to run from the power injector to the 1300. See attached notes:
Cisco Aironet 1300 Series
Cisco Aironet 1300 Series Access Point/Bridge Power Injector
The Cisco Aironet 1300 Series Outdoor Access Point/Bridge Power Injector,converts the standard 10/100 BaseT Ethernet interface that is suitable for weather protected areas to a dual F-Type connector interface for coax cables that are more suitable for harsh outdoor environments. The Power Injector also provides power to the outdoor unit over the same cables with a power discover feature and surge protection. To support longer cable runs from your wireless network switch or router, the Power Injector LR is designed to accommodate up to a 100 meter coaxial cable run plus 100 meters of indoor cat5 cable?enabling total cable runs up to 200 meters. The Cisco Aironet 1300 Series Outdoor Access Point/Bridge ships with the Power Injector LR2 and an AC power supply.

Ethernet Ports
The access point/bridge dual-coax Ethernet ports consists of a pair of 75-ohm F-type connectors, linking the unit to your 100BASE-T Ethernet LAN through the power injector. The dual-coax cables are used to send and receive Ethernet data and to supply inline 48-VDC power from the power injector to the access point/bridge.
Power
The access point/bridge receives inline power from the Cisco Aironet Power Injector (hereafter called the power injector). Dual-coax cables are used to provide Ethernet data and power from the power injector to the access point/bridge. The power injector is an external unit designed for operation in a sheltered environment, such as inside a building or vehicle. The power injector also functions as an Ethernet repeater by connecting to a Category 5 LAN backbone and using the dual-coax cable interface to the access point/bridge.

Lower than expected 1310 bridge performance

Hi All,
We have recently installed an wireless WAN link over 7 km (aproximate 4.5 milles) distance. The towers are sufficent for fresnel and earth bulge and obstacles requirements.
We have used Cisco Aironet 1310 bridges (one configured as root bridge, the other as non-root bridge). The antennas are 24 dBi from Hyperlink, connected by RP-TNC to N pigtails, also provided by Hyperlink. According the Cisco utilities, the antennas has more than enough gain for the distance, climatic and topographic conditions.
The alignement of the antennas was made visually (using binoculars) on one side, on the other with precision instruments.
To select the frequency (the automatic selection works awfuly bad, it establish connection one of three times) we use the Carrier Busy Test on the network interface / Radio 802.11G menu, where we are able to pick the frequency with zero percent (0%) utilization most of the time.
The problems we experiment are the following:
- The latency times are very variable. From 1 ms, to 207 ms, to other values. We have used other wireless equipment with more stable performance.
- There are lost packets frequently, even with the slightest network traffic (2 PC's with terminal service sessions). Supousedly, the link is of 54 Mbps speed, but the quality is very low.
- At the moment, we are losing connection every couple of minutes. After that the non-root configured bridge stays down and the only way to reestablish connection is by reseting the 1310.
- I see that the speed changes every time I refresh the IE utility.
I still havent configured any security, because the awful way the link works.
What could be the reason for such bad performance?
Best Regards,
Igor Sotelo.

Hi All,
I have noticed that when the switches have VLAN configured, the latency is very variable. In this particular case, the switches does not have this configuration. I haven't configured VLAN's on the wireless bridges either.
I will test the link without any switches, it's an good idea. Perhaps there is "something" with the wired network.
Other than that the specifics are:
- I have used Belden RG-6 1530A cable that has even higher grade than the Belden 9077 recommended by the manuals.
- The extension of the cables is around 40 meters (120 foot).
- We have installed another wireless link in the place, that uses the same frequency, but different polarity. Also we try to separate the channels at least 7 frequencies.
- The other system is omnidireccional in nature, and it doesn't have excessive gain.
- On the place where the equipment of both systems coexist, the physical separation between the antennas of the two systems is around 9 foots (3 meters).
The error messages we get are:
- On the root bridge:
Mar 1 00:00:57.238 Information Interface Dot11Radio0, Deauthenticating Station 0017.0ec6.a590 Reason: Previous authentication no longer valid

When we make a reload on any of the bridges the link reestablishes for some time. With this message on the root bridge:

I will appreciate any additional help.

Good morning,
When (1) bridge had abnormally higher retires than say the other bridge(s) this can be due to a few things. Check the config of the bridge for any odd configurations like packet shaping. Perhaps one bridge is allowing larger packets and these packets arent making it and have to be resent.
Check the phyiscal bridge solution. Is everything tight and weather proof tight. Is the antenna is good shape. Are the cables exposed in anyway.
Also what PERCENTAGE of retries are you seeing ?

Can I connect a second router to the coax cable.

In my house Verizon fios goes into a box and a coax cable comes out and splits in one direction towards a set top box and in another direction to an Actiontec M1424WR router. An eithernet cable connects the router to a computer. All is well. This works fine.
Now I want to install another computer next to the TV. It sits a long way from the Actiontec, wireless is flakey and i dread the idea of pulling a long cat5 cable through my attic to connect the computer to the Actiontec?
Will it work if I put a splitter on the end of the coax in the room with the tv, run one wire to the stb, and the other to a new router?
Solved!
Go to Solution.

Not a second router ... you want to go to your favorite online retailer (like Amazon.com) and purchase an ActionTEC ECB2200 (also called an HME2200) MoCA Ethernet Adapter. Plug and play and you're all set -- it will automatically link up over the Coax to your ActionTEC router and provide a LAN connection at the second location for you.
You can search the forums for the ECB2200 / HME2200 and you'll find numerous discussions on this device.
I use this in my home network setup and it works great.

My FIOS TV only uses the Coax cable not the HDMI cable

I can only get my STB to use the coax cable to my TV, I want it to use the HDMI cable for a better HD picture, but I do not see a way to get the STB to use the HDMI cable as the primary output. How do I tell my STB to use the HDMI cable instead of the coax? My STB is Model:QIP7100-P2.

What digital coax cable do I need for my sb 5.1 digital (pic attach

http://www.marctv.de/media/soundblaster5rear.jpg
This is my SB Li've! 5. from the back. The black whole is labeled "or digital" .
I have my Z-680 ( 5. Surround Speakers with DD Decoder) attached with 3 x 3.5 mm to have real 5. Sound in EAX Games.
But I want to connect the soundcard with my decoder via the digital coax cable because I do not play anymore.
So what cable do I need to connect my sb 5. digital to my z-680 via coax?
I need a detailed discription so that I can buy one.
And yes, I know that I only have stereo sound when I am not listinbg to a dvd.
But please give me the answer. I could not find it anywhere on the cl homepage.
Is it a 3.5 mm mono to coax? Or what is it's

Yes it's a mono 3.5mm >> RCA adapter (or a stereo 3.5mm >> 2xRCA cable). You need to use the orange socket labelled 'DIGITAL OUT'.

1310 Bridge loses connection

I work at a college campus where we have a couple of 1310 bridges between our main campus and a group of apartment buildings that we own 3 blocks down the road. One 1310 bridge is in our bell tower and the other is in one of the apartments. The other apartments have 1240 AG access points. The problem I am having is that periodically the remote apartments will loose their network connection. Originally I thought it was a problem with the remote bridge because rebooting the bridge at the remote apartment would bring the connection back up. I recently discovered that I could bring the remote location back up by rebooting the bridge in the belltower. At first we could go a couple of weeks before the link would go down now it seems to be happening much more frequently.
Any help in troubleshooting this would be appreciated.
Thanks.
Jeff

You might want to post carrier busy test results for both ends as well as signal strength readings for both ends. If memory serves you'll need commands like (check my syntax):
dot11 dot11 0 carrier busy (assuming 802.11g)
and
show dot11 ass X.X.X (X.X.X = remote end mac)

Aironet 1310 Bridges keep losing connection

There was a similar thread about this last year and I tried what was listed in there to no avail. I have 2 Aironet 1310 bridges, one as a route bridge and the second as a non-route with clients. These worked great for nearly a year, we had no problems keeping the connection up. They were not connected for the last few months but nothing was changed on the configuration, when I put them back up they reconnected just fine and worked for about an hour, not they randomly disconnect with the same message in the log entries below. Is there something wrong with them now? The are using the same antennas as before and are in the same exact locations.

I am not at the remote location any more, but the route bridge had a signal of -78 dB and a SNR of -22 dB. The non-route has -77dB for signal and a SNR of -22 dB. The location has line of sight, over water with nothing in the way.
Since I last posted I changed the fragmentation and RTS thresholds back to default from 4000 and it has been up for 24 hours now. I am hoping that it has made the difference.

1310 Bridge-Building to Building advice.

I am looking at implementing building to building wireless using Cisco 1310 bridges. This would be a backup link between the 2 buildings. The primary link is 3 T-1's. There are about 250 users connecting back here for application and internet. I am assuming that since the speed over the wireless is more than the existing T-1's that there shouldn't be a problem with latency. Am I missing anything with my thinking?
Thanks

Hey there,
If you use a BR1310 to cover 3 T1s you should be fine.
The BR1310 can get up to 54mbs (28mbs in reality due the the nature of half duplex devices such as these bridges).So even with less than ideal signal quality and strength you should have no problem getting that kind of throughput.Ideal links get in the low to mid 20s.
Hope this helps.

Aaron

Representing coax cable in Multisim

I am trying to simulate a 50 ft coax cable connected to a signal generator on the left-hand side and a 50 ohm load on the right-hand side. How would I build this using Multisim?

Hi,
The best option for you is to model the coax line as a 50ohm lossless transmission line and just calculate the delay it will introduce in second. You can use the following formula:
delay time = length of the cable/ TEM velocity (3*10^8m/s)
If you want to include losses you have to calculate the RLCG parameters of the coax cable and include them in the component Lossy Transmission Line.
You can learn more about this here.
I attached a design file that includes these components, always make sure that your load is the same as the transmission line characteristic impedance (matched) to avoid reflection.
Hope this helps,

EAP-TLS auth between 2 1310 bridges

Hello,
Am working on getting EAP-TLS auth working between a root and non-root 1310 bridge. I've had success getting LEAP working but EAP-TLS is kicking my butt.
I have an ACS 4.1 server acting as the Radius server and the auth is failing there with the code "EAP-TLS or PEAP authentication failed during SSL handshake". I think I'm missing something related to the certs but don't know where.
I can post config snippets if that will help but if someone knows of any examples configuring a 1310 or similar bridge with EAP-TLS that would be fantastic.
TIA,
BR

Hi Bastien,
it is actually what i did.
The point here i have 2 CA involved, with no relation between them.
So I did the operation twice for each CA :
-> making a certificate signing request, sent it to the CA, signed to by the CA and then imported/binded into the ACS
-> I have added the root CA of each CA into the ACS as well.
The point is when a computer, try to connect, it try to verify ACS server identity. And the ACS server only seems to present the certificate signed from CA1.
So when a computer with certificate machine CA2, try to connect, it doesn't trust the ACS server has the ACS sent its certificate signed by CA1.
I don't know how to allow the ACS to present the right signed certificated depending on the cleint that try to connect.
Then another conf I do not understand is the option:
EAP: Used for EAP protocols that use SSL/TLS tunneling --> in local cetificate, when you add a local certificate to the ACS
I do not undestand what does this option stand for ?
Then I culd see into Cisco do :
"For TLS related EAP protocols, a single local certificate is used to authenticate the server for all the TLS related protocol"
Doest it means that the ACS can use only one single certificate for All the TLS protocol configured in the ACS, to authenticate itself to the client?
Or does the ACS can use a diferent local certificate from each dedicated eap-tls protocol?
thx

1 coax cable - 2 different routers through splitter - 2 different IP addresses -- Possible?

Hello,
I currently have a verizon fios internet connection shared with my family through phones/laptops/desktops/etc. I am also starting a home business which requires constant internet usage and because of this I want a seperate line.
The wiring in my house is a bit weird so I was recommended by a friend to try an alternative method.
So, I'm wondering if the following is possible:
Currently, there is 1 coax running from the basement verizon box up to the second floor to a router. What I would essentially do is have a coax splitter at the second floor which feeds in to the two routers and each having their own verizon account associated with them. One router would have its own IP address for the family and one would be for my business with its own IP address. Seeing how coax has many frequencies, this should be possible but the billing department told me that I would need a second coax cable for a second router. This kind of ruins things completely.
So, I may have just explained it wrong to the representitive on the phone so I'm wondering if this is possible.
TL;DR Is it possible to have 1 coax cable which has a splitter which then feeds into two routers on two different verizon accounts with two different IP addresses.
Thank You.

Thank You.
Do you only want the separate line so as to not have the other traffic or do you want it so that you have a different ip address?
You can get a business fios account, that will give you 5 ip addresses.
You can run a second router off your first router and give it a different subnet that is unique for your business traffic.

Configuration of a Point to MultiPoint link with Cisco Aironet 1310 bridges

Hi All,
The previous problem of which I started another conversation here:
http://forum.cisco.com/eforum/servlet/NetProf?page=netprof&forum=Wireless%20-%20Mobility&topic=General&CommCmd=MB%3Fcmd%3Ddisplay_location%26location%3D.1ddba023
somehow dissapeared. It could have been a problem of interferences.
I have another issue with other (multipoint) wireless WAN link, which I hope has a solution.
On the central node, we have an Cisco Aironet 1310 bridge configured as root-bridge. It has a panel of four vertical polarity 17 dBi panel 90? antennas, with more than enough gain (there is a 250 mWatts 802.11 b/g amplifier, before the 4-way splitter) and excellent line of sight to three remote bridges.
The three (03) remote bridges are also Aironet 1310 models, confidured as non-root-bridges.
The problem we have is that it seems that when the three remote links operate concurrently the amount of lost packets is huge. When I shutdown the radio interfaces of two bridges, the remaining bridge makes an excellent link with the central node.
It seems that some hours are more critical than others, also the links operate much worse when there is some (small) network traffic in them.
I have read the 1310 manuals, and I can't find a sample configuration for point to multi-point links.
Does someone knows what radio interface configuration should I need to use to establish better quality communication?
I mean, perhaps the 1 x root - 3 x no root configuration is not recommendable for the multipoint link configuration.
Any hints will be welcome.
Best Regards,
Igor Sotelo.

Hi All,
Thank you for the information. I configured the distance on the root bridges, but the links showed instability.
I'm using a bi-directional amplifier. It has two pieces. According to the manuals, one is installed indoors, the other outdoors. I'm not sure if the indoors piece has the transmition module or it's only the injector.
We could establish connection at 7 km (around 4 milles) distance from the central point, using 24 dBi antennas on the other side.
However, we have issues with a near located point that is only 1.2 Km (around 0.8 milles) away and has a 13 dBi integrated patch antenna. The signal strenght value we get there is in the -62 to -68 dBm range, and is noticiably (5-10 dBm) lower than the strenght we get at other points of the link. And I have trouble establishing a high quality link with that point, using OFDM modulation. I tend to think that if I remove the amplifier I'm not going to reach that point at all. The EIRP on the central iste is 34 dBm / 2.5 watts, without amplifier it would be 26 dBm / 0.4 watts.
On the opposite sites the EIRP is 33 dBm / 2 watts using CCK or 28 dBm / 0.63 watts using OFDM.
When one looks at the central site from that point, an Motorola Canopy with passive reflector (EIRP 48 dBm or around 64 watts) can be seen. It doesn't have the same direction, but the opposite site must be large distance and could interfere with my wireless network. Attached is an amplified photo of the view. It's safe to assume that the Canopy operates in the 2.4 GHz frequency range.
Once I connect the point at 1.2 Km, the multipoint link loses its quality, and soon the lost packets get too frequent.
The CCK seems to be much more interfered than OFDM, I guess because of that canopies.
Another thing I'm wondering about is if the Aironet 1310 can continuosly switch CCK-OFDM over the same point - multipoint link, without losing packets.
What other parameters should I tweak? Is there a way to avoid interferences fromt the canopy?
I would like to apply 100 mWatts local power using the radio with OFDM, but it seems that's not possible.
Best Regards,
Igor Sotelo.

Firmware crash on cisco 1310 Bridge while upgrade to higher version

Dear experts,
My cisco 1310 Bridge old firmware C1310-K9W7-tar.123-8.jea3 is crash while i try to upgarade to the higher version C1310.K9W7-tar.124.10b.jda2 via HTTP service upgrade, any advise to get back the firmware.
rgds,
woo.

It appears that you are assigning IP address properly. For some reason we are not getting a response from TFTP server. This is typically one of 2 things:
1. Firewall on the TFTP server workstation
2. Connectivity issue between AP and TFTP server
I would check firewall settings on the TFTP workstation. Are you connecting the AP to the workstation directly or through a switch? If it is through a switch, you could plugin a different workstation to the AP switchport to make sure it could reach the server as well.
