confused by rax120 options
ok so got my new rax120 and im confused by some setup options. In wireless section there is enable or disable AX and if enabled it says it enables OFDMA however below that it has enable OFDMA for...
If you enable 160 only the device that is compatible will connect to that WiFi channel so it's best to let it run on 80. It will be more than enough.
as for the OFDMA, I've mine on on both channels testing away with a load of only ac devices and not a problem so far.
Try it and see how it goes, enable both 2.4 and 5.
ive selected 2.4 as ht40 and have the 20/40 coexistence tab ticked and ht80 selected for 5.
Ok. As for 5g Chanel is there a reason to use the upper channel like 153? I read somewhere that some features need DFS Chanel to function? Also if I use ht80 which I guess I'm going to have to is that giving me (for my pc) the 80+80 so I'm at least taking advantage of that and didn't just make my router a wifi5 router.
When you use AX 5Ghz and AX is enabled then just select ht80 which is going to be good. You don't require 160.
DFS is good if you have a congested area ie neighbouring channels or you use an extender like an EX8000 where it requires a high DFS to allow the 1733 backhaul link. Over here in the U.K. we have a small penalty when using DFS and I use channel 100 as I've an EX8000 extender. The only downside is if it detects Radar it kicks you off the DFS channels.
all AX functions are at work and don't require a DFS channel. Have a play and try out stuff. If you have a phone look for WIFI SweetSpot which will show your connection rate, don't confuse this with your internet speed. Just play with the router and try it out and see what works for you.
Ok getting it more dialed in. So I've also found in the 2.4g Chanel there doesn't seem to be anything near Chanel 9 (using analyzer) so I set to channel 9 and then test with and without coexistence. With I only get about a 290mbs rating and without I get 576. So why would I want this? I'm in a regular suburb neighborhood house so I don't believe I'm interfering with others.
40mhz can cause more interference to others and you. If performance drops on the 40mhz it could be interference but 500 Mbps connection is pretty fast and so it then just boils down to your internet speed, here in the U.K. we don't have the greatest speeds, I'm 58 down and 11 up.
in saying all that I tend to use the 5ghz for stuff like shield tv, iPad and MacBook and leave the 2.4 for other devices like my echos.ive also left my channel selection on 2.4 to auto where as other routers I pick the best channel.
