OK so I have AT&T U-verse and I also have a DD WRT router connected to it in order to obtain a different IP every time I log on to a different user account on my computer. this method is a required method in order for me to conduct my business because it gives me a different WAN IP every time.

I have been having problems connecting to the Internet, because of it. this is the second time this occurs, . The first time it occurred, a AT&T technician came over and diagnosed the problem as the DD WRT router being the problem.

He said, The DD WRT router bridged to the AT&T U-verse router needed to be properly sub netted because if not it would eventually run out of IP's...

I think this eventually happened again and I don't know how to go about fixing the problem (i.e. Subnetting. Can anyone please help me?

He also told me I needed to buy a switch to object the DD WRT to instead of directly to the at&t router/modem....

I'm just lost I'm trying to search online to get this fixed.

Currently I disconnected the dd wrt router and I'm just running through the Uverse router with the static IP. I'm also not able to connect with my windows computers for longer than 10 seconds until the connection doesn't work.

For some reason the connection is fine on my iPhone, which is where am on now.

Ok so this link

 

http://www.dslreports.com/forum/r29392345-Finally-solved-my-internet-stability-problem-with-DD-WRT

 

seems.... like it might help and I've followed it's directions.

 

I will report back with my findings. 

 

 

 

Also as an update- I am only having problems connecting to the internet VIA my business computer I am able to connect VIA other computers but my speeds are down, super down ---my speedtest.NET confirms I Have 15Mbps download and 5Mbps upload whereas it was almost triple this before???

 

My business currently is struggling I need to get this fixed because I must use the same computer and I can't access the internet from it with ipv6 addresses as I have been before this!

ok guys so it seems after using this command under Administration > Commands > Firewall
iptables -I INPUT -p udp --sport 67 --dport 68 -j ACCEPT

 

In my DD_WRT router Everything "seems to be working btter" my download speeds have gotten better since, they are at 33Mbps now as opposed to 15Mbps and my computer is connecting without any problems.

 

I still realyl don't understand what was happening or why it was happening but apparently it fixed the problem instead of having to "subnet" the two routers?
