RAX120 slow wireless download speed (24Mbps) with High Internet Speed (325Mbps)
On Xfinity Internet Service. Using a Netgear CM1200 cable modem Nighthawk RAX120 Using Nighthawk App, Wired and Wireless connections Nighthawk App reports 326Mbps; Speedtest.Net app on wired co...
The RAX120 is new enough you should either be within your 90 days of free support or your 1 year warranty to get it replaced. If the new one functions with the appropriate speeds, you might have gotten a bad device.
New Router:
Won't connect directly to cable modem and get Internet (will work on this later).
But set up as in bridge mode, cabled to RAX120 ethernet Port
So: Computer->New Modem Wireless -> cabled to RAX120 Ethernet
Speedtest (Mbps): 47.85, 244.57, 58.21, 52.83
Reconnect to RAX120 wireless
Speedtest: 19.08, 15.25, 16.76, 24.87
BTW, Upload speeds are consistently higher via new wireless router in bridge mode than connecting to wireless RAX120.
New Router: 21-35Mbps
RAX120: 11-21Mbps
I am making progress. I kept thinking "what could be the reason to throttle bandwidth?"
a) Wireless signal quality - nope, hardwire connection is similarly throttled though a higher speed
b) Wireless client capability - nope, multiple clients behave exactly the same, different router provided higher speeds
c) QOS - should be NOPE, because it's turned off, but I am suspecting this is not true. (and maybe QOS has a different setting for hardwired connection which would account for the increased but not full speed access).
I turned QOS back on and removed all rules, then added rules for specific mac addresses to make them Highest priority. Suddenly those computers have access to the full >300Mbps of my ISP connection.
In general, the admin area of QOS rules list is, at best, beta quality. You can't edit a rule, though it looks like you can. But editing a rule results in a duplicate rule and if focused on Mac Addressed, it won't let you edit/add a rule for a mac address that already has a rule. Deleting the rule causes the list of Mac Address devices to include two devices for the same Mac Address. It's all very confusing and clearly not working correctly. See attached image as an example when trying to create a QOS rule for a mac addresss.
I'm going to continue to see if setting these rules and then turning QOS back off keeps highbandwidth - in which case QOS on/off switch isn't working correctly.
After further experimentation and several resets/reboots using latest firmware in beta V1.0.1.100
QOS on 2.4ghz = horrible performance - 1.4Mbps
QOS off 2.4 = average performance - ~24Mbps
Using an older computer with wireless card that supports 2.4 only, so could be bandlimited at the client
QOS on 5ghz = excellent performance - nearly full bandwidth of ISP, ~160-300Mbps
QOS off 5 = average performance - ~24Mbps
Using a new HP Laptop and an iPad Pro 10in (gen 6)
So something appears to be throttling bandwidth when QOS is off for 5ghz
I have no idea what is happening with QOS on for 2.4ghz. But for now I can at least rely on the 5ghz.
With default set of rules
Following as I'm having similar issues with my RAX120, and have since the purchase date just over 90 days ago. On the latest (1.0.1.100) firmware.
We have gigabit internet with Comcast. Direct modem speed test is > 920mbps. Speed test on (awful) Nighthawk app is similar.
Assuming we're talking the same language... When my QOS is enabled (WMM on 2.4 and ghz anyway), I get ~30mbps / 400mpbs wireless, respectively. Wired network speeds slow, especially on my TVs (a new LG OLED and Samsung QLED), which hardwired become unusable for streaming. Disabling QOS (WMM) limits the wifi speeds to a crawl, but now the TVs show 96mbps download speed on a Netflix speed test. (I assume the TVs have 10/100 network cards?)
Enabling WMM brings the wifi speeds back up, but kills the wired speed.Enabling upload QOS doesn't seem to work, as the interface takes around 2 minutes to reboot, but the box remains unchecked.
I tried browsing / utilizing the "hidden" QOS menu but I don't understand what QOS Fasttrack VS service options are.
We have AX disabled and traffic meter disabled.My whole house is wired, and I'm extremely dissapointed in the flaky performance of this router. On the plus side... every wireless device on every floor receives a good signal.
