Hello, I will describe my problem shortly. I own a TP-LINK Archer C7 AC1750 Wireless Dualband Router. But when I connect to internet, the router shows my WAN IP Address and Default gateway address identically, as well as the subnet mask is 255.255.255.255, which means something is wrong. Because when I use other routers to connect, the WAN IP is different to gateway (the gateway is usually x.x.0.1) and the subnet mask is 255.255.255.0 (instead of 4 255s).
I still can access to internet normally, using lastest firmware (130729 from TP Link website). Can anyone tell me why is it happening? Is something wrong with my C7's WAN port?
The WAN IP address is assigned by your ISP (usually dynamically for home users) and most IPs have a mask more like 255.255.240.0 to accommodate more users on each subnet.
Your LAN gateway will be something like 192.168.x.1 with a mask of 255.255.255.0. That is all internally controlled by you.
I have not yet used that router, take a look at your manual on doing a manual set up through the configuration pages.
What model modem do you use (and DSL or cable)?
Hello, thanks for your reply. I know that my LAN IPs and WAN IP are totally two different things. Thats why I ask about my problem. I'm running fiber and my router uses PPPOE to connect to the internet (thru an ethernet/fiber converter of course).
Funny thing is, when I change to my Linksys router everything is better (the reason it's not "fine" but just "better" is because the subnet mask is not shown), I get correct default gateway and wan address. But any TP Link router (I have a WR741ND and an Archer C7) would give me the same problem (WAN IP is identical to WAN Gateway), looks like it's something related to TP-Link's design or my ISP or maybe even both...
