"Switch over to safari" to make it work. Not something one hears everyday.

[@SPXLabs]

It was either that or use edge lol. Idk why but with openSpeedTest, Omada, and Alta Labs, I’ve been having issues with Firefox. Hoping my issues were fixed in the newest versions of Firefox but idk.

[@ryanwoods4691]

Very interesting, I think TP-Link needs to come up with a solution pretty quickly given that internet connections over 1gbps are becoming more common. Great video, and great production quality as always!

[@SPXLabs]

Seems very strange that something like this would be an issue out of the box. At least they have a “fix” available now even if it’s less than ideal

[@ThiagoGuedesC]

Hey, I was the one of the people commenting about the low speeds on the other video. Glad the new fw worked for you, it didn’t for me and some others. I’m still battling tplink support without resolution, fist they said this wasn’t even possible, and now they are saying the modem is not compatible with flow control. I find it hard to believe, 802.3x has been around for decades. We will see, but I’m quite disappointed with the overall support experience.

[@SPXLabs]

I'm actually pretty surprised that it doesn't fix it. At the very least you know how video evidence of it working and can back up your claim. It's unfortunate too because it clearly can go the extra mile.

[@robmorgan8392]

thanks i thought at first it was just me but this video did help me alot upgrading the firmware. i dont understand why this had to be done..

[@SPXLabs]

Evidently this is a thing in enterprise hardware according to some Cisco folks. But it seems backwards to me. I’m no network pro so what do I know

[@akshaysathe5225]

Helpful

[@jfkastner]

Interesting ...

[@ShinyTechThings]

You gotta test at 4:43AM its the most secure time to test.

[@SPXLabs]

lol oddly specific

[@alexandrpyankov430]

No! Most secure is 4:20!

[@SimonLally1975]

That seems a little odd. I seem to get the same thing when I put open speed test docker on my unRAID server and I get full speed down (9.6-9.8Gbps) and only half speed up (5.5Gbps) it has gone faster but I made some changes and can't remember what I did. But i think it was the MTU to 9000 (6x1500) between devices i.e. just 10Gbps links and the rest staying at 1500 MTU. I currently run Mikrotik crs309 and it is fast enough for my at MTU 1500 so I leave it at that. But like I said before soon will be a move to tp-link which will be a full setup of approx. £1500 - £2000 but I am waiting for full fibre (1Gbps / 1Gbps Up/Down) till the move as everything works for my needs currently. But my main take is get open speed test on the unRAID server to do internal testing to find the bottleneck :)

[@SPXLabs]

Unfortunately I can’t modify the external MTU. But in the Omada controller it doesn’t let you set an MTU greater than 1500 on the WAN SFP+ port. How are you testing WAN speed to your unraid server? That would be cool to do.

[@jfkastner]

@@SPXLabs Don't think it's a packet size issue (or MTU/MSS) - IF you believe the TP website they say "64 Byte Packet Forwarding Rate ~ 1080 Mbps" (= 1.900k pps) and later "1,518 Byte Packet forwarding rate ~ 9970 Mbps" (= 820k pps) Unless your traffic is totally fragmented - then wireshark etc would give you some answers

[@SPXLabs]

I don’t think it’s MTU either but sometimes it can be.

[@markb4071]

did the firmware fail through the controller as you tried to update manually, rather than waiting for the device view to show new fw ( or in the app go to fw update and upgrading from there?

[@SPXLabs]

The controller did not show new firmware nor did it allow me to manually update it.

[@markb4071]

@@SPXLabs thanks. I only asked as when I tried to update a switch that way it failed. But after a reboot or two it gave the red dot of update available in the web gui (and it showed without the reboots in the app)

[@SPXLabs]

Oh word. I can’t say the same lol

[@jfkastner]

One Cisco I worked on needed to have Bandwidth Control turned on - always - to achieve full speeds e.g. if you had real 500 Mbps up/down at the Modem/ONT you needed to set the Cisco Bandwidth control limits to 800 Mbps up & down

[@SPXLabs]

That’s so weird

[@jfkastner]

@@SPXLabs IDK - the Firmware has some Bandwidth detection-regulation Algorithm and I guess that needed some help to get going ... worked wonderfully afterwards

[@SPXLabs]

Hear me out. What if, we just didn’t manage it at all and no capped it

[@jfkastner]

@@SPXLabs Test Whatever the 8411 defaults to - BUT then you should factory-reset everything, since some previous owner/tester might have screwed with those settings before

[@SerialkillerinTraining]

Hello Sir, have they sent you anything revolving around Omada Pro? what the heck is the difference between omada and omada pro?

[@SPXLabs]

Never heard of it. I’m not cool like that :(

I just saw it show up on the website and they are silver. Might wanna hit them up ;)

Try hard refreshing your browser I guess

Looks like v1.1.1 beta firmware adds flow control setting in controller mode. Hopefully a stable firmware upgrade will come in the summer of 2024.

[@SPXLabs]

Yeah that would be great.

@@SPXLabs just got the ER8411 and it looks like it's missing the ability to do multilayer. TP-Link calls it Multi-Net NAT. Instead of using the RoaS (ER8411 being the stick), I have a 100Gb L3 switch that does all the inter-vlan and routing.
