I googled this, and searched through these forums, and found a few solutions, but nothing worked so far.
Here is the problem. I have a DIR-615 in the basement hooked directly to the modem. I have one PC hardwired to it in the basement and another output to a plugin in the living room upstairs. That plugin is hooked up to a DLink EBR-2310, so I can hook up components in the living room. I am not using the Lan input on that one, just 1, 2, 3, and 4.
When I plug that router in, it disables the wireless from the 615, but the internet still feeds through to the PC, and the components upstairs have internet. One solution I read about was to disable dhcp on the 2310, but when I tried that I lost internet connection through the upstairs router and it still disabled my wireless. If I hook up one component upstairs directly, there is no issue, but I have 3 things to hookup. I've read that you should be able to use a second router as a hub, and it kind of works for everything hardwired, but then I lose my wireless (laptop, IPhone, Wii). I have three extra routers and I'd rather not have to buy a separate hub.
Just to be clear on when my wireless goes down, I can connect with the router wirelessly on my laptop, but it doesn't give me internet access. When I disconnect the 2310, I have to reset the 615 for the wireless connection to have internet again.
I had some initial problems with wireless on my 615 when I first got it, and uploaded new firmware which fixed it. I was having this same problem before I uploaded the new firmware too.
Thanks in advance for any suggestions.
