Slow speed with RAX 80 on Wifi

[Chorgey]

I have a 300Mbps speed package with Comcast. When I plug the desktop directly into the CM1150V, I get download speeds of 325.9 Mbps, Upload is 8.7 and 16ms for ping.

When I connect the desktop to the RAX80, the download speed drastically drops to 9.1 Mbps, Upload is 12 Mbps and 17ms for ping.

If I run the desktop wireless, the speeds are 8.9 Mbps download, 7.7 Mbps upload and 18ms ping

Firmware version is 1.0.2.76_1.0.35

I had several support tickets opened and I've only had this for a little over a week.

We have two iPhones (6SE) and they are getting speeds of ~270 Mbps

When I run the Netgear app and run a speedtest, its averaging around 356 Mbps

Why does the desktop (directly connected to the modem) get the correct speed and when it is connected to the router, the speed drops but other devices are fine?

I just wanted to update on the situation. I needed a BIOS update and after downloading/installing, I am getting the speeds that I should be getting.

a couple things you can try.

1. factory reset and manually reinstall the router. The rax devices are pretty new and after firmware upgrades, respond very favorably to resetting and reinstalling. 

2. Make sure if you reset/reinstall, leave access control, parental controls, traffic monitoring, qos disabled. They're not recommended >250mbps. 

3. Check your cables. it wouldn't be the first time a cable caused an issue

4. Try a different pc. Like the cables it wouldn't be the first time a pc/laptop was having issues with its wired port

5. try enabling ipv6.

Thank you for the information, I'm going to work on it this weekend.

Mine is slow too...

You needed a BIOS update? Do you mean firmware for the router, an iOS update, or something elsewhere? What firmware are you running? I am on V1.0.2.76_1.0.35

Can you also let me know:

• what channel you selected? 
• Do you have AX on or off?
• Do you use QoS?
• did you enable IPv6?
• are you in 5GHz 4800Mbps, 2400Mbps, or 1200Mbps mode?

Thanks!

You needed a BIOS update?

Yes

Do you mean firmware for the router, an iOS update, or something elsewhere?

I have a Dell Desktop, after going to their website, I ran a system check and it shown that my BIOS was out of date, I downloaded and installed it.

What firmware are you running? I am on V1.0.2.76_1.0.35

I am also on Firmware Version V1.0.2.76_1.0.35

Can you also let me know:

• what channel you selected?  On 2.4Ghz, I am on Channel 11 and on 5G I am on Channel 161
• Do you have AX on or off?  ON
• Do you use QoS?  OFF
• did you enable IPv6?  NO
• are you in 5GHz 4800Mbps, 2400Mbps, or 1200Mbps mode?  2400Mbps

also, in Advanced>Wireless Settings for both 2.4 and 5G, I have...

Fragmentation Length 2300

CTS/RTS Threshold 2301

and in ADVANCED > Setup > WAN Setup...

In the MTU Size field, I entered a value of 1472

as suggested by support.

Don't forget to Power Cycle..

>> remove the router from the main power supply.
>>remove the modem from the main power supply.
>>wait for 2 min
>> power ON your modem.
>>once the modem is stable then power ON your router.

Hope it helps... this was driving me up a wall for a little over a week.
