# Downloads speed starts ok but after a few seconds they go down to 10kbps?

Since yesterday any file I try to download from any host start downloading ok (at >1mbps) but after a few seconds the speed start to decrease down to 10kbps.

I use a mobile modem (huawei) and I connect to a wcdma network.

What could be happening? I use kaspersky, and I checked the Network Monitor and I don't see any weird process using bandwidth.
