Hi guys, I'm using stock TM riger modem

Past few days have been experiencing very frequent DC (more than 15 times per hour) and very slow speed (0.5 Mbps via speed test). Area Sri Petaling

My SNR margin and Line attenuation are both in the very bad category.

Called up TM and they helped to reset connection and port, but the problem continues.

Anyone else encounter this problem and any way to solve it? Thanks.
