Possibly related, with satellite some LNBs suffer from a temperature-
dependent frequency shift. I had signal loss on sunny days, which Sky
didn't believe, and they switched decoders twice before i convinced
the tech to change the LNB. He conceded that it was "quite warm".
Better-quality LNBs have a PLL to avoid this.

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?
