I have an TP LINK TL WR703N V1 running with a wifi link to my home demotica system

The unit is running on;
OpenWrt Attitude Adjustment 12.09 / LuCI 0.11.1 Release (0.11.1)
Kernel version     3.3.8

Connected to the USB port i have a gateway reading values and transmitting it to the home demotica system

I have a steady wifi (ip) connection between my system and the modem; i can contact the 703n with web client, putty and winSCP without any hick up.

It seems to me that the usb connections is not stable; cause after every reboot it works good for 1 to 2 minutes, than it looses the connection and created different connections;

If i look at the active connections i see a list like this (running up to 160 active connections)

IPV4    TCP    192.168.2.75:1001    192.168.2.100:43120    40.00 B (1 Pkts.)
IPV4    TCP    192.168.2.75:1001    192.168.2.100:55140    40.00 B (1 Pkts.)
IPV4    TCP    192.168.2.75:1001    192.168.2.100:51613    40.00 B (1 Pkts.)
IPV4    TCP    192.168.2.75:1001    192.168.2.100:44263    40.00 B (1 Pkts.)

So what can it be?

Pls advice

@nebbia88
followed link and found route;

thanks

second question;

i have to connect hub after rebooting

during reboot it does not find hub

third question

in start up file tp link is given

echo "1001:raw:15:/dev/ttyUSB0:9600,NONE,1STOPBIT,8DATABITS" > /etc/ser2net.conf
ser2net

can i create 2nd usb data entry at hub by using

echo "1001:raw:15:/dev/ttyUSB0:9600,NONE,1STOPBIT,8DATABITS" > /etc/ser2net.conf
echo "1002:raw:15:/dev/ttyUSB1:9600,NONE,1STOPBIT,8DATABITS" > /etc/ser2net.conf
ser2net

and port 1001 goes to usb 1 and port 1001 goes to usb2

is that correct?

pls advice
huib

Have you built and flashed a new version of the 703N firmware which fixes the USB disconnect problem?  Or used a version from trunk?

Your second echo to ser2net.conf will overwrite the first.  Use ">>" to append; ">" creates the file.

There has been a report that the usb-disconnect patch has been backported to AA, but the dates on the built files in AA had not changed as of yesterday.

You may have the problem of not knowing which ttyUSB# is assigned to which device.

You should be able to install it with sysupgrade.  Make sure you also download all the packages you need immediately with opkg.  Trunk is a moving target, and later downloads might be out of sync.

Otherwise you can build your own, and may need to if trunk+packages is too big.  Self-built is smaller.

@lizby
Have tried to upgrade, have learned a lot but was not succesfull
was able to restore the original settings and back up

a night to remember

could you be so kind to provide a list of which packages to update and to which version
i can find the installed packages in through the web acces, so if i can update the one needed it would beperfect

rgds
huib

so, what did you do (step by step) and what failed?

On your current machine, try "opkg list_installed" to see what you have installed at present.

Normally i work with the web acces.
This time i copied the file using winscp in to the /tmp folder

Than by using putty i used sysupdate as per wiki
Reboot and waited 5 to 10 minutes,  power off on and the following stps as per wiki

Reboot and no acces through web acces

After a couple of hours i used the original firmware file used the same route and restored acces throuhh
The web acces 

I would like to update the usb part to have the usb 1.1  working

How do i update, by using the web acces the file as fiscribed in post no 2

on trunk snapshot there is no GUI preinstalled.

if you want luci you have to configure internet access and install it:

http://wiki.openwrt.org/doc/howto/luci.essentials

Have now installed other usb hub and now it is running for about 6 hours, so post no 2 was succesfull
So basic question solved
Thanks
Huib
For other question will make new item
