connection question

i got a tmobile modem-gateway monday and tried to connect it up to the c3700 modem router unit and i did not have any luck, i did unplug the modem from comcast so all it was doing was the wifi and ethernet or so i thought. this unit has 2 ports so i connected 1 to the tmobile modem and the other 1 to my network switch, but i just did not have any luck with anything i had on the network switch, all my cameras went off line and my roku and my pcs. i tred tuning off the radio and turning it back on and still all my network was down.

 

so i have a linksys router and that has the yellow port that goes to a modem and it has 4 ports for devices. so i hooked my network switch to that on port 1 and and the tmobile modem to the yellow ethernet port so after redoing all the ip addresses i got the cameras and roku and pcs to be seen. and got online again.

 

so can someone help me figure out how to connect the c3700 to the tmobile modem and be able to see my network or is that modem/router not able to do that? if not then i think the linksys will have to do the job, but now i can't see my cameras when i'm away from home. i have them ported but maybe someone here has the tmobile 5g modem and can tell me how to get the cameras past that device . thanks bp

  • so as i started this thread i ented c3700 n600   that should take care of the model and i said netgear modem/router.

    and i said i tred to connect the tmobile gateway wich is the same name netgear calls their modems and people on this site complained that i calle it a router they said it was a modem so it seems everyone has ther own name for these and it is all the same you call it what you want i will call it a gateway. they said a stand alone device that connect to the internet was a gateway and the device that you connect your devices to was a router. i went down this road a few times

     

    i gave enought information for someone to help.

    i said i got the tmobile modem and disconneted the c3700 modem from the cable company and took a cat5 cable and plugget it into port 1 on the netgear and prot 1 on the tmobile modem. but my personal devices would not connect eother ethernet or wifi to the netgear modem. they would connect the the tmobile modem via wifi but not thru ethernet.

     

    but now it does not matter as some other forum has this same issue and as it turns out the tmobile modem is just a glorified hot spot and not a real modem. because it uses wifi to connect to it system. it just happens to be it uses 5g.

     

    so on the tmobile forums they are all complaining about not being able to do the exact same think i was here asking help for. so it may be awhile before this happens or it maynot ever happen. so now people like me that have a smart type home if they use the hotspot will not be able to contact there home devices thru the tmobile modem, unless tmobile changes the system.

     

    thanks

       A maker and model number is not "in depth".  Which part of "actual"
    did you find confusing?

       Knowing approximately nothing about your devices, what you did, what
    happened when you did it, what you want to accomplish, or anything else
    useful, makes it tough to provide specific advice.

       Thanks for that detailed description.

       Why?  Is there some actual problem which you're trying to solve?  Or
    some actual goal?

       Thanks for that detailed description.

     

       "no luck" is not a useful problem description.  It does not say what
    you did.  It does not say what happened when you did it.  As usual,
    showing actual actions (commands) with their actual results (error
    messages, LED indicators, ...) can be more helpful than vague
    descriptions or interpretations.

       If you want to try to use the C3700 as a wireless access point, then
    you might see, for example:

     

          https://community.netgear.com/t5/x/x/m-p/1463500

     

       That's written for a Netgear C6300-as-WAP, but the steps are about the
    same for any other router (any make/model) which lacks a one-step WAP
    option.  (I'd expect a C3700 to be very similar, but with fewer LAN
    Ethernet ports, less useful.)

       Regarding "can't", see "not a useful problem description [...]",
    above.

     

    > [...] i have them ported [...]


       For the non-psychics in your audience, you might reveal what that
    means to you, and where you did it.  Some clues as the the IP addresses
    of all this junk might be interesting, too.

     

    > the tmobile 5g modem [...]

     

       How is that related to your (unspecified) "a tmobile modem-gateway"?
    "modem" and "gateway" are spelled differently for a reason.

     

       If "ported" meant that you configured port forwarding on some router
    or other, and then you add some other router, it's just possible that
    you'd need to do something different to keep your port forwarding
    working.  IP networking is often more complex than connecting a bunch of
    extension cords together.
