No internet output

No internet output

I have a nighthawk X6 router.  If I connect with a LAN to the internet modem I get good wifi and internet.  If I connect the internet modem to a Netgear FS105 and then connect a LAN to the router I get no internet.  The wifi connection to the router works fine.  Also if I connect a computer to the FS105 with a LAN I get internet.  I tried the wifi connection with two different laptops and got the same result?  Suggestions?

Too bad it has to work that way.  Looks like I will have to run two cables from the basement to the router which will be on the second floor.  One for input to the router and one back to the switch.  But, thanks again.

   Connect what with what, exactly?  A "LAN" is a Local-Area Network".
Do you mean "with an Ethernet cable"?  What, exactly is your "the
internet modem"?  If you're talking about a wired connection, then what
does "wifi" have to do with it?

   Still confusing, but, generally, one would connect only the router
(WAN/Internet port) to an "Internet modem" (whatever that really is),
and a switch like an FS105 would be connected to a LAN port on the
router.

   What, exactly, are you trying to connect to the Internet?  (Wired
computers, wireless computers, ...)  Are there not enough LAN ports on
the R7900 for all of your wired devices?

   An FS105 is a 10/100MHz switch, which makes it slower than the
10/100/1000MHz (gigabit) LAN ports on your R7900.  (Unlike, say, a
GS105 or similar gigabit switch.)  If you have more than one old/slow
wired device, then it might make some sense to connect those to the
FS105 (and one of its ports to an R7900 LAN port).

> Suggestions?

   Do more description and less analysis.  Do not invent and/or misuse
technical terms ("LAN"), when a simple description ("cable") would be
clearer.  Provide an accurate, detailed description of your equipment,
and your actual goal, rather than ask why some arbitrary/goofy
arangement of equipment is not working as expected.  A typical cable has
two ends; when describing a cable, say where both ends go.  A router may
have many ports of different kinds (LAN, WAN/Internet).  "connect a LAN
to the router" conveys much less useful information than, say, "connect
my Windows laptop Ethernet port with a cable to a LAN port on the
R7900".

Re: No internet output

OK.  Sorry for the loose terms.  I have an FS105 switch connected to an fiber optic modem ( where the internet comes into my house) via an ethernet cable.  Also connected to the FS105 via separate ethernet cables are a desktop computer and the Nighthawk X6 AC3000 router.  I have very good internet conectivity on the desktop. I had wifi signal connection from the laptop to the router but no wifi internet service .   Now I must state that after messing around for about an hour and getting no internet through the wifi I made my first post.  Well, lo and behold, it somehow is now working. Is it possible that the "slow" characteristics of the FS105 made it take so long for the router to recognize the internet signal? The reason I have the FS105 between the modem and the router is that my desktop computer, printer, smart TV are all in the basement and I want the router on the second floor to get good wifi coverage outside the house and to a shop a couple hundred feet from the house where one of my laptops will be located.   I'm guessing I should have gotten the GS105 instead. Thanks again.

   Is the (unspecified) "fiber optic modem" also a router?  If not, then
connecting a switch to it might be very unwise.  If so, then you may
have problems in some cases from cascading the two routers.

> [...] Is it possible that the "slow" characteristics of the FS105 made

   Probably not, but any change in the wiring could confuse some
devices, especially when two routers are involved.

> I'm guessing I should have gotten the GS105 instead.

   It would be more appropriate for the devices with gigabit ports.

   If the "fiber optic modem" is also a router, then it might make some
sense to configure the R7900 as a wireless access point.  That would put
everything on one big LAN, which would eliminate any two-router
problems.  Visit http://netgear.com/support , put in your model number,
and look for Documentation.  Get the User Manual.  Look for "Use the
Router as a Wireless Access Point".

This is in my opinion, the best approach for your big houre.

Updates.  The modem is not a router.  Another interesting thing I discovered.  If the ethernet cable from the FS105 to the router is pluged into one of the four output ports of the router  I can get internet wifi but if I plug it into the yellow Internet port I get nothing.  If I connect the modem directly to the routers yellow port via an ethernet cable everything works fine.

Re: No internet output

All your systems must resde on the LAN/WLAN side of your router. Direct conections to the "Internet" as you have done using the switch on the Internet or WAN side are in general limited, the ISP only assing one (or very few) public IP addresses - to use on a single router typically.

 

The data path must be:

 

FTTH---Modem---WAN-port---Router---WiFiLAN-ports---Switch---otherSystems

   In that case (as already explained), you should connect only one
thing, normally your router, to it.

   You lost me on that wiring description, but the key point is that (as
your ISP has configured its stuff) your modem can be connected to only
one device which has an IP address (directly, or through a switch).  If
you connect multiple devices to it, then at most one of them can work
(and even one would be questionable).

   That should do it.  It's that, or else put a router near the modem,
and a wireless access point in the remote location.  A second cable
probably costs less.  (But, if the basement router had enough gigabit
Ethernet LAN ports, then you could discard the FS105.)  As usual, many
things are possible.
