network slows when using a network switch
a few weeks ago i was getting about 70 mbps on my internet. then i got a message from xfinity that i was going to start getting 100 mbps speed. well i checked my speed a few days later and i was gett...
ok i had to return that c7000 modem. comcast told me the reason i was not getting the 100 mbps was that modem is not compatible with there system for my area! when i put the c3700 online i got 55 to 60 mbps and when i put the c7000 online i got 40 to 50 mbps. so it may not be entirely the network switch, that switch may have some issues but comcast told me to put the c3700 back online as that one would be better for now. they told me to get the motorola mg7700 that i see on ebay now is better. and will work on my system and they told me it is capable of 150 mbps. so i will try for one of those modems and let you all know how that one does for me. i will get at lease 1, 4 or 5 port 10/100/1000 switch for the laptops and the cameras can stay on the 10/100 switch. thanks
What is the Mfr and model# of the external LAN switch?
Is this switch supporting of 100Mbps or 1000Mbps connection rates? If it's only 100Mbps, then this could be one problem. Most switches now days support 1000Mbps.
Try a different switch. Be sure it's 1000Mbps rated, non managed and non green ethernet featured.

now i'm sitting next to the modem and if i plug in a 100 ft. cat cable i still get 112 mbps but if i pug in any length cat cable to a network switch it drops down to 60 or so mbps.
can anyone tell me why this is so? a few weeks ago it was 75 plu mbps with the switch connected to the pc. i even reset the modems and factory reset them and still it is the same if i pug intot he back of the modem it is 112 or so mbps but with any type of network switch it drops down to 60 with the c3700 and 40 with the c7000 modem. help me figure this one out. thanks
thanks. my netgear switch is a 10/100 switch and the model is fs116. i have been told this switch is not fast enough for the 112 mbps internet speed. i was getting 70 to maybe 75 mbps before i was told they upped my speed. so now i just reconnected back up to the c7000 modem and have a 10/100/1000 switch on the way. so when i get that new switch i will see if things improved. that might be also why my cameras are a bit sluggish when i look at them with my phone or the monitoring tablet by my pc. they show great on the monitor plugged into the dvr and the nvr just like watching tv. they are sluggish on the phone and tablet using the wifi. now that i have the c7000 modem/router that may get better. and installing a faster network switch may improve that more still.
some of my cameras also connect to remote switches but they may not be throttling them down the first unit to change will be the 16 port switch to the 10/100/1000 swithc and see how it goes. thanks for the help when i get it installed i will return and let everyone know if it is working better. thanks.
Ok thanks for confirming what you have. Yes, the 100Mbps switch is not fast enough to support anything over 100Mbps.
The newer 1000Mbps will resolve this.
