Hello, I have been having problems with my swm5 lbn. It is mostly when it starts getting cold at night. Freezing temps. I lose reception. Today it worked fine til the sun went down and the temps dropped. No signal. I did the usual connection check but nothing. I then put my old lbn on and bingo it works fine again until tomorrow probably. Anyone know of an answer to this issue? The 2 lbn's I have are different manufacturers.
