Hey guys, I have some trouble with my home network and I'm running out of ideas. I don't like to ask for help but here I am, a little desperate as well to be honest. :(
The network components:
Switch (10 clients, 1 server (Windows Server 2008 R2 with AD/DNS/DHCP), 1 router)
Now I bought a new Router (ASUS AC66U) for the second floor, which I configured as Accesspoint so I can use WLAN, also connected to the switch.
I flashed DD-WRT and everything seemed to work fine, but sporadically I lose Internet connectivity on my WLAN connected devices. Later I discovered, that I also lose connection on my clients when that happens.
I ran a wireshark capture on one of the clients and what happens now (reproducible) is that when I open a URL I get lots of TCP DUP ACK and TCP RETRANSMISSION packets, the site opens very slowly, if at all. Now the interesting part: When I turn off the AC66U and open up a site it instantly loads and there are maybe 1-2 retransmission packets.
I didn't run the wireshark trace on other firmwares I tried (ASUSWRT Merlin, stock firmware and TomatoUSB by Shibby) but the symptoms are the same.
In the source of the packets I see the MAC adress of the first router, which connects to my ISP and I guess there is some kind of conflict but I am by no means an expert to network related stuff.
I would greatly appreciate it if someone could guide me through the setup of DD-WRT to coexist peacefully with the other router or give me some useful hints on how to solve this problem. :)
Thanks! Please let me know if you need more information on the setup.
