Networking conundrum, please help

[Master Disaster]

OK, I apologise in advance but this is going to be a long a complicated one.

 

So a few months ago my parents adopted a 10 year old and as part of the adoption process it was mandated that my mum needed to have parental controls setup on her network so stop the child from accessing social media. After looking at the parental controls on her router I decided that they weren't suitable for the job. There is no client access control feature, parental controls are either on or off for everybody (its a really stupid design) which means that when enabled she can no longer access facebook (which she uses to keep in contact with friends who live abroad).

 

I suggested she buy a wireless access point which I could use to setup a separate WiFi network with parental controls enabled and the child can use the second network while my mum uses the first. After speaking to a family member she was given a cable router from my uncle which he bought, realised it was for cable not dsl and never returned it so I spent about 2 hours on Sunday fitting the second router for her.

 

So the setup goes...

 

Phone line > DSL Filter > Sky Router @ 192.168.1.1 (with DSL modem) > Cable router @ 192.168.0.1 (I will explain the gateway address choices later)

 

After fitting the cable router it became apparent that the new router had much more involved parental controls with client specific access and it also supports 5Ghz WiFi as well as G/N/AB WiFi, he old router only supports 2Ghz & G/N and it will only work at N as long as there are no G devices connected so I decided to fix another issue she has had for a long time which is WiFi blackspots in her house.

 

Originally the old router was using 192.168.0.1 so I swapped the old router over to 192,168.1.1 and disabled the WiFi entirely then set her new router to 192.168.0.1, I then changed the SSID to exactly match her old SSID and changed the password to exactly match her old setup too. By doing this all her existing WiFi devices connected right up to the new network with no issues. WiFi network is now sorted and the blackspots are gone.

 

The problem arises from her cabled devices. She has a NAS which she uses to store all her work documents as well as movies and music which she streams over the network to her laptop, android box and TV. She also has a network switch which splits one cable into 2 to connect up her TV and android box (this was done so we only needed to run one cable around her room instead of 2).

 

While setting the new router up I connected all her wired devices over to the new router and I thought this was OK however it turns out the new router only supports 100Mbps over ethernet and now when she tries to stream anything it is constantly buffering.

 

To fix this issue I decided to simply plug all her wired devices back into the old router and this is where my problems start.

 

Turns out that wired devices connected to the old router are not accessible to anything connected to the new router (which is obvious now that I think about it) so I'm stuck in a catch 22, either I connect everything to the new router and the ports aren't fast enough to stream movies or I connect to the old router and nothing can see them.

 

My initial thought was to set the old router as DMZ in the new router but this isn't possible because the issue isn't down to port forwarding (again obvious once you think about it).

 

There might be some really obvious solution I'm just not seeing but how can I get this setup so all wired devices are connected to the old router but still accessible to devices connected to the new router?

 

Help!!!!

Try using a gigabit switch from the cable router to get a gigabit network for the wired devices. Transfers between wifi and wired will be same as before.

You could also try having the routers on the same subnet, just disable dhcp and dns serving on the new one and set the ip to be on the same subnet. Remember to use an ip that wont be in use by other devices. The filtering may not work with this setup though, depends on how its implemented. 

Other possibility is to have the new router as the dhcp server, but you would need to be able to change the gateway address it serves to match the old routers ip. I assume this would be a more "pro" feature so it may not exist on regular routers.
