Router will not get dynamic IP (WAN?) when connected to bridged modem

[skywere]

I have put my modem that i received from my ISP in bridge mode, the LAN cable leads to a switch that has 8 ports on it, 3 go to pc's and 1 goes to my router.

All the pc's work fine and have no trouble connecting to the internet, but the router doesn't work at all, before i put my modem into bridge mode the router worked fine but now it won't, it's sending a wifi signal and i can connect to it from my laptop, i searched google for a bit and i found that i should look at my WAN, i looked again but it's empty, no address etc.
Restoring to factory settings, leaving off for some time and power cycling doesn't work.
The router is a TP-LINK TL-WR1043ND. (white one if you search it on google)
Feel free to ask for more info, i really want it fixed.

I hope at least anyone here can help me, thanks for reading

How is your router connected to the switch, through the router's WAN port?

Also, I feel like it would make more sense to have the modem plugged into the router WAN port, and then connect one of the router's LAN ports to the switch.

So it would go:
modem
|
router -------wireless devices
|
switch -------wired devices

The router is connected through the WAN port yes, I also tried to directly connect the router to the modem which didn't work either.
Everything worked flawlessly before but when i changed my modem to bridge mode the router just gave up.
I also tried and changed it back and then the router works again, but i really prefer it if i could put it in bridge mode.

Wait, just realized your router four gigabit LAN ports. Any particular reason you need the switch?

I forgot to mention 2 consoles that i have on LAN cables, seems useless but the switch wasn't expensive and it seemed worth the try to speed things up on them.

Why do you need the router in bridges mode? The purpose of a wireless bridge is to connect devices to a wirless network. You current setup has no need for a bridge.

Once the modem is in bridged mode it won't handle the authentication values to the ISP, now your router has to do that as well. Usually the authentication data is preset on the modem by the ISP so you'll need to call them and see if they'll configure/give you the parameters for your router.

It's the modem i want to have in bridge mode, the problem is that the router can't access the internet with the modem in bridge mode.
The reason that i want bridge mode on my modem is because i got an IP ban from Twitch's entire site and bridging my modem was the only way i could find to change my IP address.
The reason i got the IP ban is because I spammed too many people with a referral code to CSGO gambling sites.
I learned my lesson but i highly doubt Twitch will show me mercy.

Ill keep this in mind if nobody has another solution, thanks

If what u need is to change your Public IP address, it might be easier to request an IP change from your ISP than to get them give u the authentication data.

@skywere have you confirmed that putting the modem/router in bridge mode actually allows you to circumvent your twitch ban? Because although it may change the local IP addresses within your LAN, your external facing IP address (the one that twitch likely banned) is assigned to you by your ISP, and I don't think changing things up within your local network will change it.

@RaDiKal_ I recently changed my router/modem from my ISP to bridge mode (I already had my own router I wanted to use), and getting the authentication info from my ISP was trivial. I just sent them an email and they replied with the username/password I needed to enter into my router WAN settings. Although asking for a new IP address from the ISP may be the true answer to the OP's problem

As soon as i put my modem that my ISP provided in bridge mode i can access Twitch again, only problem is the Router.
