great!!
(should I build a cement barrier?);
I had timeouts like this with the wireless phone
(then went out a bought an encrypted phone for this purpose);
now the microwave is causing the same issue.(silently though);
like what I had mentioned, the microwave causes this when
it's cold started, making wonder if the waves are better handled
when the metal or grate is warm as opposed to cold.
(molecules are jumping around as opposed to moving around);
in any case as long as that microwave isn't active the internet
connection seems O.K.(knock on wood);

regards;
