New - RAX120v1 and RAX120v2 Firmware Version 1.2.9.52 Released

This came in via Auto update today on my v2. This is for v1's as well. Installed the update using auto update, then power cycled OFF then back ON then factory reset and setup from scratch. Mines in...

    So I tested my RAX120v2. 
    1. Connected behind a Orbi 970 with a 10Gb LAN Port.

    2. Connected behind a SXR30 Pro with NG GS-108 1Gb 8-port switch in between.

    1 6ft CAT6 UTP cable connecting the RAX120 to it's source device while in AP mode.

    1Gb Windows 10x64 PC

     

    First test is with RAX in AP mode connected with it's MG port to the Orbi 970 10Gb LAN port and 1 wired PC connected to the RAX120v2 LAN port in back. RAX was first set up in router mode and it's Internet port section there set to the 5GB Internet port and applied. Then AP mode was configured for static IP and the configuration applied:

    Wired PC connected to LAN 4 port.

     

    Second test is with the RAX in AP mode with it's INTERNET port connected to the NG GS-108 swithch connected behind Orbi SXR30 router and 1 wired PC connected to the RAX120v2 LAN port in back. RAX was first set up in router mode and it's Internet port section there set to the Main Internet port and applied. Then AP mode was configured for static IP and the configuration applied:

    Wired PC connected to LAN 4 port.

     

     

    Third test is with the RAX in AP mode with it's INTERNET port connected to the NG GS-108 switch connected behind Orbi SXR30 router and 1 wired PC connected to the RAX120v2 MG Port:

    Wired PC connected to the MG port.

     

     

    Throughout all testing configurations above, I never saw any speed results below 900Mbps for the DOWN and 50Mpbs for the UP while the RAX120 was in AP mode.

I would compare the electrical power parameters of output line drivers for LAN ports and this Multi-Gig after 30-40 meters of the copper cable during throughput load on the oscilloscope...

    It doesn't mean anything without electrical input sensivity measurement of your Gigabit Switch input ports and RAX120's raw electrical output level of Multi-Gig port.The short distance between RAX120 and Gigabit switch is below 30 meters of cable I suppose, what can additionally mask the problem. Test Uplink on long wire. Be like engineer in electronics with raw physical data arguments and power of signal, not just rundom test data on your particular config without testbed physical parameters. You proved that your config doesn't discover this bug, but my config still does. That's all. Your good suggestion to try out other switch port in the outgoing router as workarounded was correct, but not resolved the real cause of the problem. The same gigabit switch works flawlessly with all other than Multi-Gig RAX120 ports. Try to find the real cause, not mask it. I would like to the see signal power and SNR parameters more after 30-40 meters of cable's distance from Multi-Gig and LAN ports.

    It works for you, doesn't respond to my question, why is it not working for me.

    If You eat burger and fell good after it, is less interesting case than the other one, who eated it and had stomachache or even died after it 😉

    Something you'll need to look into and see since your the only one that seems to be exhibiting this issue. Need to rule out all your equipement and cables. All cabling types and kinds have been suggested. FW is working as well as the RAX120 hardware in it self testing in normal home invironment and configuration. If you feel the need to dive into it more, thats up to you. Make contact with NG support and let them know what your experiencing.

     

    Good Luck.

    Thank You for our fruitful discussion. My 3com switch 3C1670800B must have too weak input drivers required for RAX120 Multi-Gig output port (uplink), but for RAX120's LAN and Internet ports are enough. I've replaced switch to 3com 3C16792C and problem is not visible. Hardware parameters of output are the cause of problem for 3C1670800B. This is not a router problem.

    You might try some other branded switches as well. NG would be recommended. Apparently what your using isn't working. 

     

    Those model switches you have, the one model you posted reports to be only a 100Mbps switch which would NOT be recommended at all. Would be a bottleneck on a 1000Mpbs ethernet connection which the RAX supports. 

     

    The other model seems to be a 1000Mpbs supporting switch. However these 3com branded switches maybe of older generation and have no idea how they are designed and may not be really compatible with NG routers let alone the MG port speeds. I recommend keeping same brand of router with same brand of switch. 

     

    Though the MG port supports speed down to 1000Mpbs, I'd try and install a MG supporting switch on this port to ensure it's working fully at 5Gb regardless if you have that need of a speed or not. NG GS110MX should be reviewed. 

     

    If your only using 1Gb Switches, then configure the RAX for the 1Gb Internet port while in AP Mode. Theres no need or sense in using the MG port for it's main connection to the host router if the speed is only 1Gb. 

     

    Also use of CAT6A STP cabling should be used, short or in long lengths if that's what's needed.
