How about this? http://www.controlbyweb.com/webrelay/ I've used these before and it works pretty well. If you use 2 of them together, you do not need to use a computer. - Original Message From: Chuck Profito cprof...@cv-access.com To: WISPA General List wireless@wispa.org Sent:

Thanks for all these good tips. The items below are the things we have tried so far with no success. We are using smaller channels, H-pol. Filters have not helped the problem, noise floor is actually pretty good, C/I of about 20 on most CPE.. We are going to try the two setting changes that Daniel

John Tranzeo released a new firmware update the other day that has helped my 900 system a lot. Better signal and much faster pings. I have been fighting the same problem as you for the past couple of months. Terry - Original Message - From: John Scrivner j...@scrivner.com To:

Well as far as I know, I just did a test upgrade though, it turned a useless B only tranzeo into a b/g tranzeo with 5/10/20 mhz channel widths. Regards Michael Baird Curious - on those older cards does it still listen at the default of 20 mhz channels like the older Atheros cards? Josh

Seems to me it is ethernet cable picking up EMP. I seem to lose a lot of Netgear routers lately. Seems to go right through the POE and gets the WAN port. Also Transmit side of XR2's. Always see receive side degrading after mid path lightning strikes even a mile away. Trango ethernet survives.
