Small Info:
Router Model Linksys E4200
Firmware Version DD-WRT v24-sp2 (03/25/13) big - build 21061
Kernel Version Linux 2.6.24.111 #14325 Mon Mar 25 03:31:23 CET 2013 mips


I have two servers and those getting 13x http video streams and distributing them to the users. Ihave also 25x internal streams.Total traffic is under 100 Mbit/sec. Every stream almost 2Mbit/sec and at the same time I am uploading them to maximum 6 users at the same time (peak time). Therefore the traffic is really low.

I am living random disconnects and connects. Sometimes ocuuring this in 24 hours a few times. Sometimes I am not living any disconnects for 48 hours. After this problem I changed the download/upload server to another and plugged new cat6 cables. But nothing changed. Those servers connecting direct to router.

before the thinking the device change I am suspicioning from the firmware. I am living these types disconnects also with internal networks. (sometimes internal and external stream disconnecting at the same seconds.) What would you like to suggest me at this point?

This appears to be Broadcom b53 driver bug that is yet to be resolved. To check for error messages, on DD-WRT, try to go to Administration, commands run this:

dmesg | grep eth0

Default logging level does not provide much information however. You might want to flash Kong 22000++ or Advanced Tomato for better connection rates and for hardware NAT support.

First of all many thanks for your help. This disconnects are really annoying. Because my customers dropped from IPTV system.

I executed this command according to your advice:
Code:
eth0: Broadcom BCM47XX 10/100/1000 Mbps Ethernet Controller 5.100.138.9
roboswitch: Probing device eth0: found a 53115!
device eth0 entered promiscuous mode


Meanwhile I have another e4200 which works on Tomato shibby. I installed on "tomato-K26USB-1.28.RT-MIPSR2-136-Mega-VPN" What do you think is would help this disconnects or should I install another firmware. What is Advanced Tomate? Is there any temporary fix to reduce this problem? Because my system installed on another city and far away from my location? Every disconnects makes me really annoying.

Advanced Tomato is basically the same as Tomato by Shibby, except with fancier GUI.

To remedy your problem, you could try to flash your router with a newer build like dd-wrt.v24-29739_NEWD-2_K2.6_mega-nv60k.bin or Shibby/Advanced Tomato for Hardware NAT support.
