sun's effect on wireless

Does any one know if the heat of the sun can affect a wireless network?
We're using Netgear gear.

Ours keeps going off in the day (during this fine weather) but is fine at
night, early morning and early evening.

Are you operating this equipment from a flat rock in the middle of the
desert?

Excessive heat can affect any electronic equipment, but it's unlikely to be
the cause of your problems.

What exactly happens when your service "goes off"? Do you lose wireless
connectivity to the router, or are you simply unable to access the internet?
Without more specific information, possibilities include excessive internet
traffic and radio interference.

Heat can definitely cause adverse affects but only if your equipment is
exposed to heat. Other possibilities come to mind, such as maybe during
the day someone else nearby is using a wireless device that kills your
signal... do you have some potent flourescent lights maybe?

Yes, it can.

Two possibilities come to mind:

The trivial idea is to look at connectors, antennas etc., everything
exposed to direct sunlight. Maybe some contact inside a connector breaks
up due to the thermal size changes when heated/cooled.

The other possibility is existing, although only seldom. Is this a long
distance link, maybe spanning a valley?
We have had problems with a real long distance link crossing the River
Rhein valley. In summer the air was heated and stared to rise in bubbles
from the valley. These bubbles are definetely of a different density and
lead to refractions and reflections which can severely influence a
microwave link. Afterwards we found out that this is a well known
phenomenom on links over valley and troughs, where the air is not
exchanged horizontally, but can only rise vertically, i.e. on a windless
day.

Yes this is a long distance affair, altogether covering over ten mile with
Hop Stations, and it certainly goes through the countryside, with valleys
and hills (they tend to go hand in hand don't they!). So you may be on to it
there.

Any known solutions?

We are going a few miles across countryside. We lose wireless connectivity
to the router.
We can rule out excessive internet traffic.
We point the network in four different directions from the top of a church
tower, and there are problems in more than one direction.

This is taking place over several miles in different directions and so is
unlikely to be another wireless device.

Someone else suggested looking at all connections for evidence of
contraction/expansion problems. If your equipment is in weather-proof
enclosures (outdoor equipment should be), are you getting condensation
problems on humid days? What about wind - is your antenna moving slightly?

As of this writing you have several suggestions:
(1) Direct sunlight induced thermal effects on equipment.
These can affect electronics, cabling/connectors, and
even focus - if mounts (including buildings/towers)
shift even slightly for any reason (including thermal).
(2) Heat-induced refraction layers. Sources can include not
only the rolling countryside effects mentioned but also
such heat sources as large paved areas (not necessarily
blacktop), factories, railroad roundhouses and railyards,
and any number of like scenarios.

You might also consider carefully that there are some radio-
frequency operations that might present interference during
daylight hours. Lowpower radio transmitters are one example;
in an urban area it's possible that crowds of people on
cellphones (and using other wireless gear) might present
a problem. And atmospheric thermal refraction effects that
might redirect any number of distant transmissions at one
or more of your antennas are another example.

When I use my microwave oven, my wireless does not work.
