Have struggled with 6 pair of ENH500 all day today and cannot get them to cooperate. I have over 6 years’ experience with them and have been finding lately that when set up in WDS bridge mode, most times #1 will see #2 but #2 will not see #1 or vice-versa. Makes no sense.. In this case we require 4 units to see each other. That is not happening no matter how they are configured. Updated the newest BIOS, reset, started over at least 5 times. WDS does not work as bridge, Access point/client station cannot not work in this environment as the access point must be at the end of a line where one of the ENH500’s cannot see that access point.
