mess up with the setting need help

[salvanost]

hello, i'm using gargoyle set by my friend last year, now i cannot contact my friend by some circumstances, so i change the setting by myself

here my old setting
Modem(bridge) -> (via WAN slot)Wireless router (PPPoE) -> DCHP

DCHP 192.168.2.2- 192.168.2.254
set the router IP into 192.168.2.1

due the WAN slot router not responding, caused by rain storm yesterday

i change my setting on wireless router
from ethernet LAN modem -> WAN wireless router
into ethernet LAN modem -> LAN 1-4 wireless router
this way i still could using my wireless router wifi by modified some setting
then i change the network setting into
modem(PPPoE) -> (via LAN slot 1-4) wireless router (static IP) -> DCHP

DCHP 192.168.2.2- 192.168.2.254
set the router IP into 192.168.2.1

while using static ip
192.168.1.10
gateway 192.168.1.1
not all client could connect into the wifi

then i'm using default static IP from gargoyle (i forget the detail)
10.0.0.10
gateway 127.0.0.1
all client could connect to the wifi, but more problem occured

the problems:
0. all connected clients could connect into my modem setting (192.168.1.1)
1. i cannot access and monitor my wireless router via 192.168.2.1
2. looks like DHCP not working properly, all connected client, got IP 192.168.1.2-192.168.1.254
my old QOS bandwitdh monitoring using DHCP 192.168.2.2 - 192.168.2.254
so all client get louse bandwith

what should i do so
1. i could access my wireless router again
2. i could using DHCP setting from wireless router so my old QOS still working properly

any recommended wireless router i can buy without looking for specific version? especially tp-link?
looks like impossible to buy old version TP-Link TL-WR1043ND here...

how about TP-Link TL-WR941ND?

No need to do so much complex setup, just reconfigure your VLAN configurations and change one of the LAN port to WAN

Yes, you will need to use SSH/SCP to change this..
