There is a real solution to the problem of downloading and disconnection Using Bt in the intranet! (Source to btchina Forum)

I used the ADSL modem route to access the Internet. It was plagued by the cause of the disconnection when I used the BT download for the first time. In particular, the NAT port ing was enabled. At that time, the IP address of the ping modem was intermittent, the Internet industry cannot be opened, but it is no problem to use the Internet Express. At that time, I thought there was a problem with the built-in modem routing, so I searched the network, finally, I found a complete solution on a forum.
This solution applies to the Viking ghost film (for example, the Asus aam6000ev series sent by most telecom companies, I, Viking ghost tablets from Shida, and I use aam6000ev/G3 FROM CHINA TELECOM ).
Here I want to talk about the cause of this disconnection: in the default configuration, the IP Session of the modem is set to 192, that is, up to 192 IP sessions are allowed, in addition, this ipsession should contain all sessions, such as the NAT session and the session between the host and the ADSL cat. When bt is mounted, the probability of disconnection increases. One feature of Bt is to establish a large number of connections at the same time, which is an important factor for the IP session to reach the limit. In the bridge mode, there is usually only one PC connection and one PC connection, rarely reaching 192. If a route is enabled and multiple computers are connected, the number of connections will be doubled. In particular, the number of connections to BT will increase significantly when the port ing of NAT is used, even if the traffic is not large, it is easy to make the ip session of the adsl modem reach the maximum value, causing the ADSL cat to fail to respond. therefore, you must increase the maximum IP session value.
Well, the operation is essential, as shown below:
1. Use telnet to log on to the ADSL modem:
Enter Telnet 192.168.1.1 in the command.
192.168.1.1 is the IP address of the ADSL Modem. If you haven't changed it, this is the IP address.

2. Enter the user name
Password login

3. Enter the following command)
(A) $ modify nbsize maxipsess 500 (set this number based on your needs. I set it to the maximum value of 500 and aam6000ev/G3, and there will be no more ), however, modem production will increase a lot)

(B) $ commit

(C) $ reboot
After the three steps of ABC are completed, the modification will be completed after the ADSL restart is completed.

View the maximum value of an IP session:
$ Get nbsize
Max IP session: 192 (if this value is the one you modified, it indicates that you have succeeded) http port: 61580
Telnet port: 61581

The Nat session can be seen through the following command:
$ Get Nat status
Or:
$ Get Nat rule status (number of Session connections under port ing)

In fact, if the quality of a modem is good, the maximum number of IP Sessions of the modem is 1000 by default.
After I modified the IP Session, the average speed for downloading with BT was about KB. When the three files were downloaded together, the disconnection basically disappeared. Well, I wish you a pleasant surfing !!
