Dear sir,

I'm using the TD-W8968 Router for internet sharing from a USB Data Modem at home.
The USB Data cards i tested are 1. Huawei E353 3G 21.1 Mbps and 2. Huawei E392 4G LTE

The tp-link w8968 router connects and works well with both the modems
but the problem i'm facing is of internet speed.

When i connect the USB Data cards to the the laptop directly i get a 6 - 7+ Mbps internet speeds
but when i connect the data card to router i'm only getting 1 - 1.5 Mbps internet speed over wifi any channel.

i also tested with some other high speed 3G data cards (Huawei and ZTE) and got same speed results

also there is a BUG in the latest firmware while creating a port forwarding configuration.
Although the setting gets saved but it does not show in the list on the webpage.

Please help
