PECHS Exchange

In the past few days, my DS margin drops to 0 and then changes to an abnormal value of 2147483647. My friend has the same issue and we both desync/disconnect a lot.

I think that this might be the issue from the exchange because at times, my DS margin increases to 21 and while for some hours, it says between 12-20 but the abnormality happens at random times.

I'm using Shrio Modem.
