Recently bought an ethernet hub TP-LINK TL-SF1005D and I'm trying to have my PC wired to one port and then have my router (Dlink RTN56U) in another so I can have a device wired but still have a wireless network for phones, tablets etc. Initially, I had the router connected to the hub and it was working fine but my wired laptop couldn't get a connection (invalid IP address or something). Now I have my wired laptop working but the router can be connected to but has no internet access. I'm not that knowledgeable when it comes to this sort of thing if anyone could give me some help. Thanks!
