NZNOG-People, I have just finished migrating all of the mailing lists held at The University of Waikato from one server to another. I don't have any reason to believe that anything's gone wrong, but please bear with me for today if it turns out that something has. - Donald Neal -- Donald Neal | Q: How many Aucklanders does it take to change Systems Programmer/Analyst | a light bulb?

Wow thanks for all the responses. In reply to Neil Fenemor: I can definitely see how thermal things like that and the way heat moves could effect things, the building we link to isn't too far away but the route as the crow flies is directly over the city and therefore a lot of asphalt and whatnot so I can see how that would cause problems. I imagine there's not a lot a lot that can be done to prevent/circumvent that other than changing to a different connection method. Irt Mark Foster & others regarding heat: This definitely sounds like something I'll have to look at further, I know the trango unit does have some kind of internal thermometer (probably for this very reason) so I'll look into a way of graphing the output from that. What kind of temperatures would be classed as too high? 40-50deg? Irt Dave, I'll reply off list. Cheers all, Michael Btw hopefully the weather keeps up, would be nice to see a warm end to winter :) ________________________________________ From: Ben Deller - Airnet NZ [mailto:ben(a)team.airnet.net.nz] Sent: Tuesday, 1 August 2006 4:22 p.m. To: Michael Davies Subject: RE: [nznog] Wireless link adversly affected by the sun?

Hi there, As the subject suggests, I've been noticing an interesting problem with our internet. We're lucky enough to be on the receiving end of a wireless net connection running through Trango broadband hardware, fairly conventional wireless tech. However I've noticed through monitoring the connection with smokeping to various places around the country that the connection quality seems to decrease dramatically through the middle of the day, but not every day. At first I thought that this was simply related to congestion somewhere, but from following the weather a bit I've started noticing that it gets worse on the nice sunny days. For example: Today, a balmy 17 degrees in Dunedin and beautifully sunny all day. Packet loss and jitter begins to increase at about 9am and peaks about 1pm with 60% loss, then at 2pm as if flicking a switch it returns to nearly 0% loss. From looking at the graphs over time, this does happen quite often but not every day and the loss today is definitely the worst I've seen it (but also the warmest/sunniest day we've had in Dunedin for quite a while). Has anyone seen or heard of this happening before? Would there be any way to prevent this - supposing that the sun is the culprit - short of installing a Mr. Burns type sun shield? Regards, Michael

Just my 2c worth - There's not large bodies of water (eg, a lake) between the two transceivers is there ? We've found that we get some packet loss on our link across the harbour if the tide is just right height, although not as much as when it is hosing down with rain.. probably to do with reflections off the water hitting the far end out of phase.. And nice sunny days tend to produce nice calm flat reflective lakes.

Whoops, meant to reply to this one too in my previous message. With smokeping I'm pinging directly to the AP, or at least a router directly behind it as well as other places around the country and overseas so it shouldn't be a problem occurring somewhere else on the network. I'll attach a graph showing the pings/loss from today. Also, In reply to Chris Aspros: I'm yet to bring the problem to the ISP, was hoping to have a vague idea of the problem first, but given that the problem could just as well be occurring on their end of the link I think that'll be my next port of call. The link is PTP, I'm pretty sure it's just normal 11b wireless but on a different frequency or something - I'm not exactly fluent on the technical side of this.

What sort of antenna do you have? If your link distance is pushing the limits of your hardware, a tiny amount of thermal expansion could potentially reduce the signal past the operating threshold. Unlikely, but possible. Alternatively, could there be other equipment nearby which becomes more active on sunny days? Some sort of secondary effect?
