Hi
i did not understand well what you trying to do
when you say connection is not good what sympots appearing?
wireless or wired?
If you want to use your own router best is to go at SH and tick modem mode
This will disable the router mode of the SH and wireless
Plug the cable to lan 4

then connect your own router there to lan 4 of SH and use your own router wireless
for access in modem mode is 192.168.100.1 and router mode is 192.168.0.1
If you reset SH you loose previous settings
