I have map request tryout errors all the time its some crap modem wants from cmts but dont get but in the end it doesnt matter as long as your connection works. Errors you wanna worry about are things like T3 or T4 timeout errors.
reply to DelmarPip Map Request Retry Timeout is not issue with signal or noise at all, those are T4 or T3 time out errors you are talking about. Map Request Retry Timeout B603 is just some info that the modem wants from cmts thats simply not available or simply cmts dont care about it, its not signal issue. As far as that other thing z00.0 mimo not sure about that one.
However, the Map Request Retry Timeout B603 I have occuring every hour once and its just something one can disregard as far as I have learned.
