The current setup for this company has been extremely unstable and slow. I don't have a lot of experience in this area so I was hoping someone could give me a few pointers. Currently, both locations are using Linksys WRT54GL's flashed with DD-WRT firmware (Yes, 802.11g. All extra bells and whistles are disabled in the firmware. They were set up for WDS so other wireless clients could connect to the same access point, with varying degrees of success. Not very important). They are connected to SmartAnt 2300-2500 MHz 14 dBi directional antenna mounted on the roof (extended pretty high for perfect line of sight). I'm not sure when they got these antenna exactly but I'm told it was when WiFi was very new. The network is very small so both locations share the same subnet (192.168.1.0/24). They have gone through numerous Linksys access points over the years. The wireless settings are tweaked as best as possible, and we have found the connection to be most stable when the TX is limited to 6-9 Mbps. We have explored other options as well. An internet connection at each location + VPN is out due to very slow upstream speeds (the buildings are in an industrial area, ADSL is the only option.) The max they offer on regular business accounts is 800 kbps up. T1 lines are even slower and even more expensive. They won't offer us any other solutions such as fibre. We have considered running fibre/coax but there is too much construction activity and other property in the way. I'm looking into RouterBOARD right now, considering a RB433AH and R52H wireless card, but I'm not sure this will actually solve the problem. It's difficult to determine if the issue is with the antennas or access points (for example, after a good thunderstorm, the wireless link will be down for at least 12 hours, but will fix itself eventually. Resetting either access point will keep the link down for at least 30 minutes. Using an airgun on the access points tends to make them more reliable, even if they are clean and dust free. From the admin interface, each access point will report seeing a very good and strong signal from the other, yet they refuse to communicate until they feel like it a few hours later.) Any suggestions welcome. I'm sure you can tell cost is a bit of a factor here but it will be easy for me to justify a higher price if I'm confident it will be effective. While I'm at it, I've been reading along on the list for over a year now; thanks everyone for sharing your real world experiences :) Peter ------------------------------ Message: 2 Date: Thu, 18 Jun 2009 09:18:24 -0400 From: Jared Mauch <jared@puck.nether.net> Subject: Re: Wireless bridge To: Peter Boone <NANOG@Aquillar.com> Cc: nanog@nanog.org Message-ID: <20090618131824.GA25957@puck.nether.net> Content-Type: text/plain; charset=us-ascii On Thu, Jun 18, 2009 at 09:05:56AM -0400, Peter Boone wrote:

I've had good luck with Cisco Aironet gear running in repeater mode. I've done the cheap linksys thing as well and it just did not work as well as using some equipment that was better designed. I have actually found the non-IOS software on the aironet 350/340 to be more usable than the IOS software. You need to have your network be consistent. You also have the obvious interference challenges with any unlicensed deployment. - Jared some of the equipment i've used: http://cgi.ebay.com/5-Cisco-Aironet-350-WAPs-AP352E2R-A-K9_W0QQitemZ200351697798QQcmdZViewItemQQptZCOMP_EN_Routers?hash=item2ea5e44b86&_trksid=p3286.c0.m14&_trkparms=65%3A1|66%3A2|39%3A1|240%3A1318|301%3A1|293%3A1|294%3A50 http://cgi.ebay.com/Cisco-AIR-AP1121G-A-K9-Aironet-1100-1121-Access-Point_W0QQitemZ190313803887QQcmdZViewItemQQptZCOMP_EN_Routers?hash=item2c4f96306f&_trksid=p3286.c0.m14&_trkparms=65%3A1|66%3A2|39%3A1|240%3A1318|301%3A1|293%3A1|294%3A50 -- Jared Mauch | pgp key available via finger from jared@puck.nether.net clue++; | http://puck.nether.net/~jared/ My statements are only mine. ------------------------------ Message: 3 Date: Thu, 18 Jun 2009 09:21:56 -0400 From: Patrick Shoemaker <shoemakerp@vectordatasystems.com> Subject: Re: WISP NMS recommendations To: nanog@nanog.org Message-ID: <4A3A3F74.6060601@vectordatasystems.com> Content-Type: text/plain; charset=ISO-8859-1; format=flowed Although this would probably be better suited for one of the WISPA lists, I'll respond here anyhow since there seems to be some interest. For managing Canopy elements, Motorola Prizm is probably the way to go. First of all, you'll need it to handle element authentication for your PtMP system. It will also do configuration management, alerting, and all the usual NMS stuff. It's also *possible* to get it to work with other SNMP capable devices if you want to manage other vendors' equipment. It will work out of the box with the Canopy PtMP line, PtP devices, powerline carrier devices, and (I think) the MotoMESH line. It gives you all the info you need at a glance for each element: configuration history, RF power level plots, bandwidth utilization plots, alert history, etc. FYI if you haven't used it, Prizm is a pretty clunky and slow Java-based package. The features are nice, but configuring it can be a chore.
