Please excuse what might be a novice question. I am wondering if I can daisy chain routers and still use dd-wrt effectively, i.e. connect a dd-wrt compatible wi-fi router to my existing router.
The reason I am thinking of this, is that my existing router is an LTE/4G router using a SIM (I lived on a boat, and now I'm back on land the available speed in my area is relatively poor - 10 Mbps).
There are some LTE/4G models supported by openWRT but 2 are Chinese hardware that a friend advised me against (suggesting the hardware might not support the full feature set), one is a dongle and one is a D-link router I am considering.
I would rather use dd-wrt but can find no supported LTE/4G router. Searching on the forums, there are suggestions to use an LTE dongle and plug into a dd-wrt compatible router. I am guessing I would get better connection and speed from my current 4G/LTE TP-Link router though and so would like to keep using it if possible.
Hence wondering if I can install dd-wrt on a suitable router, connect it (LAN to WAN socket?) by ethernet to my current LTE/4G router, and have all my home devices then connect to this inner/dd-wrt router.
I am unsure if daisy chaining the routers like this would work, and if putting dd-wrt on the inner router and not the outward facing/internet connected router would limit the usefulness or functionality of the dd-wrt install?
I did make an effort to look on the forums for this into but relevant sounding posts quickly got technical in a way I didn't fully understand!
You can daisy chain without a problem be sure that your primary LTE router has a different IP subnet from your DDWRT router.
There are drawbacks but for normal use it is no problem
Thanks EGC. I have got a small travel router to experiment with and am trying to make a logical map of the network and going over my subnetting theory.
I'm not sure if I should have:
LTE router 192.168.1.1 /24 ==Ethernet LAN to WAN sockets== dd-wrt router 192.168.2.1 /24
255.255.255.0 ====================================== 255.255.255.0
or
LTE router 192.168.1.1 /24 ==Ethernet LAN to WAN sockets== dd-wrt router 192.168.1.129 /25
255.255.255.0 ====================================== 255.255.255.128
The first would put them on different networks, but the second would put the dd-wrt router on a subnet, which I would then connect all my devices to? I should set static addresses for both routers, disable DHCP on the outer/LTE router and allow dynamic DHCP on the inner/dd-wrt router?
I feel this is basic stuff but am still learning networks!
Thanks egc. Lots of useful info in that link. And better, more precise ways to describe things too! e.g. "a gateway router that is downstream of a primary gateway router".
