Let me explain the situation: I have wireless router, that connects to DSL modem, that later goes to ISP(by f-connector if it matters). Then I have two problems with it:
1) Wireless router gives the ip addresses like 82.197.xx.xxx and also(!) the default gateway of 82.x.x.x. The thing I don't understand - why is it so, when the local IP of router is 192.168.0.254, so my home network must be within this address pool. For some reason it gives addresses that belong and go straight to ISP. Internet works fine, but why is it so?
2) Second question is more serious - I have gone to internet from my house using several devices for my life here(4-5 devices maybe), but few days ago I tried to connect my friend's iPhone to the internet and it seems that router doesn't want to give address to it. I mean the device can find the network, you click "connect", type password and then nothing, no IP address is given to device. I tried the same with my friend's laptop - no address again. So can it be that the ISP give only limited number of IPs tied to MAC addresses and doesn't use NAT/PAT? If so - how can I forget some devices to use new ones?
Answering expected questions:
Yes, the IP addresses on different devices are different, seems like no NAT/PAT here.
Yes, other laptops can't get the IP address EVEN through Ethernet cable.
The router is in AP configuration mode.
Router is TP-LINK TL-WR702N
