Re: [WISPA] 5.8GHz Link Loss
Guys, I think you have a classic case of multipath fading. The things to check are: 1. Is there enough fade margin to achieve the desired availability (99.98% - 99.998%)? 2. Is the first Fresnel Zone blocked 40% at K = 4/3? 3. Is the reflection point as close to one end as possible? Is it blocked? If you send me the following I will do a path analysis for you. Antenna gain at both ends, dBi Cable loss at both ends, dB Tx power output, dBm Rx sensitivity at BER = 10-6 Antenna height at both ends, AMSL in feet Path length in miles Mike -Original Message- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Marlon K.

[WISPA] [Board Approved] 60 miles in 3 days! Everyone Deserves a Lifetime!
Before I get started with my cause and reason for sending this email I want to apologize if this email is deemed inappropriate for this list. I feel like over the years of being a member of WISPA and this list I have come to appreciate each of you as a type of online family member so I hope I do not offend or waste any of your time. I asked the WISPA board for permission before sending this email and I truly appreciate their consideration and thoughtfulness in allowing me to post this completely unrelated list topic. I also wanted to give each of you a chance to join in this cause as many of you or friends and family unfortunately may have been touch personally by this disease. My wife and her best friend Kim walked the Susan G. Komen Breast Cancer 3-day 60 mile walk in 2002 when Kim was diagnosed with breast cancer and fighting the disease. She was in remission for almost 5 years when she was diagnosed again. Kimberly Teems Marques lost her life in May of 2008 at the age of 42. Last October my wife Gayle and 5 other friends and family walked the Tampa Breast Cancer 3-day again, in her memory as Team Kimpossible. I spent the weekend in Tampa cheering them on the entire way. The event was so inspirational in it's cause, magnitude, and the walkers' sheer passion that I felt compelled to participate as a walker this year. Aside from the challenge of walking 60 miles in 3-days, each walker is required to raise $2300 in order to walk. I have been funneling most of my contacts to my wife's fund raising efforts since she is much more connected to this than I am, and as a result, I am going to be struggling to raise my $2300. What I don't raise of the $2300 comes out of my pocket. The motivation for doing this is far greater than the risk of not raising all the funds so I am not giving up! J Some of you may be touched and motivated to make a monetary donation to our effort. If so, there is a link in the signature of my email and every $1 is greatly appreciated. Many of you have websites and or your own audience via Social Network sites. Helping us spread the word and cause via those outlets would also be greatly appreciated. We are trying to attract sponsors for fundraising events, raffle prizes etc and as you well know, the more traffic we can show, the better our justification for sponsorship. More information on how to help us on Facebook or your website can be found via the http://continuekimsfight.com http://continuekimsfight.com site. See the right hand column link for Spread the Word. Thank you all very much for your time. If you respond to this email, to prevent any further off-topic emails to the list, please reply to me directly. I feel I am stretching the list etiquette as it is sending this.

Re: [WISPA] 5.8GHz Link Loss
Has the link changed completely? Or does it come and go with time of day? Are both ends of the link at the same height? If so, the reflection point will be roughly half the path. If not, the reflection point will be closer to the lower antenna. Has anything changed in the terrain at the reflection point? Are these paths urban or rural? Could there be some new growth at the reflection point? If the phenomenon has not passed, it may not be tropospheric ducting. Although ducting can persist for a day or so, if it's still degraded, probably not. If the path is over an urban are it may be Rayleigh fading, or Rician fading if the path is over trees and such. Did someone else show up and start shooting across your path, especially at mid path? There is a wealth of knowledge on this list, but we still need some more info.

No, nothing new. This has been an ongoing issue for years. Does not last all day and does not happen every day. Can start as early as 8pm but usually after midnight. Usually gone before or just after sunrise. (Has occurred during daylight on rare occasions - I'm going to have to start a log just for this event!). Seems to be predominant in the summer. I see it happening to short links (PtMP) also, just doesn't get bad enough to drop. My gut feeling has always been that it's temperature/pressure change related.

[WISPA] Mikrotik Redirect

This script will occasionally redirect the clients web browser to a notice page that lets them know there account is past due and offer a payment page. If they refresh they should be able to continue browsing. This is intended to be multipurpose, informative to the user in case they forgot to pay, offer a quick way to get caught up and be a tad annoying until paid.

Well, I can tell you why this is happening. Remember that each image, each CSS/Javascript include, etc, are all seperate HTTP requests, so if you are interrupting every fifth request, you are also going to end up blocking every fifth include (for reference, my twitter page has 54 src attributes in it, so your rule would break a random 20% of twitter for me). So far as how you would accomplish that, perhaps 1.2.3.4 needs to respond with some javascript to pop up a new window, or force redirection of the existing window. There is no simple way that I can see to be able to do what you are trying to do with just Mikrotik rules. -- Josh Cheney josh.che...@gmail.com http://www.joshcheney.com WISPA Wants You!

Re: [WISPA] Mikrotik Redirect
I used to do what you did, but it resulted in many errors on the page as you encountered. Using the web proxy works better but still won't solve your problem completely. This will redirect all 'deadbeats' to the web proxy, which will then only allow them to your website. /ip firewall address-list add address=192.168.1.5 comment=deadbeat customer who needs to pay! disabled=no list=deadbeats /ip firewall nat add action=redirect chain=dstnat disabled=no dst-port=80 protocol=tcp src-address-list=deadbeats to-ports=8080 /ip proxy set enabled=yes port=8080 /ip proxy access add action=allow comment=your servers name here disabled=no dst-host=www.whatever.com add action=allow comment=your servers ip here disabled=no dst-address=1.2.3.4/24 add action=deny comment=url to redirect them to disabled=no redirect-to=www.whatever.com/pay_your_bill.html Josh Cheney wrote: sa...@michianawireless.com wrote: Really did not work as planned.
