Negative Output Power and Haywire Stats in Router

This has been the scenario since yesterday. What could possibly be the problem?

Th upstream power and rate are very very high than usual, and the downstream rate is very low, it should be 2048 Kbps. The funny thing is that the output power is negative.

change to G DMT

These are my current settings. G. DMT seems to be enabled. Do you suggest any changes in these settings?

uncheck other modulation choices. keep bitswap. and try. someone reported T 413 selected today.Presume modem beetel 220bx.

I changed the settings to these -



And now the stats are -



Much better, but still not as good as before.

BTW, another question, I've been using the previous settings since more than 2 years, so why has this problem come up now, all of a sudden? Has MTNL changed some setting?

P.S. - is register.bol.net.in opening for you?

Has MTNL changed some setting?
