There's no way it should have to be that labor intense just to figure out why upload speeds aren't nearly what they should be when an old Verizon g1100 router can deliver equal DL/UL out of the box. Judging by how many people have this issue and that Asus isn't bothering to fix it, I'm just going to return the ax86u and be done with it. It's nothing special to warrant keeping it.

Yes, a few extra steps are necessary. Hardly labor intensive though.

I can understand not wanting to do so. But as you've seen already, it is not just an Asus issue.

For the record, all the RT-AX86Us I've deployed, including my own, do not exhibit such issues (running RMerlin firmware).

You can try something, or not. But hardly fair to lay blame when you didn't take steps to see if simple misconfiguration is (part) of the issue.
 
Yes . Doing that will fix your wireless upload issue.

If you think you missed up your router setting trying people suggestions to fix the issue , do a reset then connect asus router to the isp modem/router (for example lan1 from isp router to wan on asus router ) then when you are at the router setup wizard change operation mode to AP
I'm a dunce when it comes to routers and networking, so let me throw a specific use case at you... I use Verizon Fios. The ONT (Optical Network Terminal), which is essentially the modem for Verizon, sits outside the house. I have an ethernet cable running from the ONT to the ASUS router inside, which I plug into the WAN socket on the router.

You're saying to take the ethernet from the ONT (outside) and plug it into a LAN socket? and then switch the router into AP mode (Access Point(AP) mode / AiMesh Router in AP mode) in the "Administration>Operation Mode" Section of the router settings? Or am I still plugging the ethernet cable into the WAN socket and setting it to AP mode? Or do I have this all wrong?
 
let me correct that . I used Ac68 with dirty flashes and got the full speed.

It feels like asus is ignoring this intentionally and doing the ISP’s a favor

Wait wait wait…. if you think that asus ax routers are horrible for cutting your upload speed to exactly %50 upgrade to their new axe routers and you will get %15 of your wireless upload speed
Here's a better question, would it make sense to ditch the AX86u and just grab a AC86u? Or does the AC86u have other issues? I've only got 1 device that uses the AX signal and that's a Fire TV Cube... but it sits 10 feet from the router and was perfectly speedy with the AC connection.

The main reason for me upgrading the router was to get better 2.4ghz speeds (was getting maybe 50mbps DL max for some reason), and range (needed an extra 20ft of range to cover the entire house). The ax86u definitely fixed the range and 2.4ghz speed issues (not blazing fast but faster than I was getting in any range and covered the extra 20ft I needed). But if I can get the range and speed for the 2.4ghz connection and keep the upload speeds symmetrical with the ac86u, that may be the solution I'm looking for.

Sorry for the multiple questions.

Yes, run an ethernet cable from the LAN port of your Verizon-supplied modem to the WAN port of your asus router. at least that's what I believe was meant by IAAI for resolving this issue - or is this what you had already done in the first place?

The line coming into the router is from the Optical Network Terminal (ONT, which acts as the "modem" For Verizon fios). I'm not sure if it's a Lan or Wan port it's coming from on the ont. But I had it plugged into the Wan port on the Asus router.

I'll see what IAAI says, but imagine it can't hurt to try it.

it's okay , we are all here to help and learn from each others experiences.


what isp speed you currently paying for ?
what is your internet usage ? how many devices get connected to the router ?
are you going to save money returning/selling the ax86 ?
what is the size of the house are you trying to cover ?
do you use a nas/hard drive (Network Attached Storage) connected to the router ? if yes. are you transferring/streaming large files locally ?
are having a slow download or upload internet speeds ?
share your setup and settings with us or dm me if you are not comfortable sharing it in here.


* connect your fire tv cube to ethernet if you can, for speed and reliability concerns.

I pay Verizon for 400/400 but will upgrade to gig speed soon cause the cost is so low.

I have an unraid server that is connected via ethernet. The apps are internet accessible via reverse proxy using nginx (swag docker). Upload speed is moderately important because of that but because it's a wired connection, I usually see the speeds I'm paying for plus a bit of extra. I'm not transferring huge files like 4k or remux. 1080p for the most part with the largest file sizes around 15GB but mostly under 10GB.

Wirelessly, I have 3 streaming devices connected via wifi using the 5ghz connection. The cube gets 350DL/150UL, tivo 4k stream is at 120/120 and hisense TV running Google TV getting 220/180. This is on both the fios g1100 and Asus ax86u.

On the 2.4ghz network, I usually have 2 phones, 2 tablets, 2 chromebooks, a printer and a ring doorbell and 2 laptops. Not all at the same time, but a few at a time (probably 4 at a time along with 1 5ghz connection). Speeds on that 2.4ghz connection range from 35/20 at close range to 15/10 for longer ranges using the g1100. With the ax86u close range went up to 95/50 and long range went to 50/35. And the range was extended by about 20 to 30ft.

Ive toggled the settings on the Asus as well as I could switching things on and then off to see which settings helped most. But that upload speed via wifi on the close range is odd to me (it could be a device issue). And tbh, UL speed on those devices is less important than the wired server (which upload speeds seem to be fine wired).

I suppose my question is, does the AC86u provide the same range as the AX and not have the reduction of UL speeds over wifi. At one point the g1100 had equal DL/UL and the 2.4ghz network had more range. But it's 4 years old and figured the age was just showing.

Was hoping the ax86u wouldn't hurt the upload speeds and improve the 2.4ghz speeds a lot.

House square footage coverage... 2800 Sq ft. Router is on the middle floor of the house. The ax86u was $200 (unopened return via Amazon). I factory reset it once I got it up and running and rebooted a few times since tweaking it.

Ideally, I'd like equal DL/UL on all wireless devices and good range for the 2.4ghz network. A 1gb ethernet port for the server.

Not sure if I'm being unreasonable to think this router should allow for the equal DL/UL or not. At the end of the day, this ax86u will work fine, but if the AC86u can provide the same range and I can get equal DL/UL via wireless connection, I'd probably opt to return the ax86u and go with the AC86u... Big IF though.

Thanks for your help.

Yes that's what I meant

Old setup: OTN > Asus AX router in (Wireless router mode / AiMesh Router mode)

New setup 1 (if you really need asus AX router) OTN > ISP router or Asus AC router > Asus AX router in Access Point(AP) mode / AiMesh Router in AP mode

New setup 2 (without asus AX router) OTN > Asus ac router in (Wireless router mode / AiMesh Router mode)


I suggest one of following steps

(A) Clean

1 - Backup your router settings choose Administration under Advanced Settings > Restore/Save/Upload Setting > Save setting. http://router.asus.com/Advanced_SettingBackup_Content.asp
2 - Reset your router using (Factory default) and select (Initialize all the settings, and clear all the data log for AiProtection, Traffic Analyzer, and Web History) http://router.asus.com/Advanced_SettingBackup_Content.asp
3 - Choose one of the suggested methods above new setup 1 or 2 and connect your router to the internet.
  • setup 1 = OTN cable to > ac router wan port (once router is configured and internet is up) > new cable from ac router lan1 to ax wan > now move to step 4 configuring ax router to become AP
  • setup 2 = OTN cable to > ac router > now move to step 4 configuring ac router to become AP
4 - Connect to your router using wifi or lan and it will be ax if you chose setup number 1 or ac if you chose setup number 2 as if it's new router . http://router.asus.com/QIS_wizard.htm and choose Advanced Settings > Operation Mode > Access Point(AP) mode > Automatic IP > chose your wifi settings.

5 - Once your new ap is up, log in and change settings to your linking . ( That's another topic I will cover later on ) o_O


OR


(B) Dirty

1 - Backup your router settings choose Administration under Advanced Settings > Restore/Save/Upload Setting > Save setting. http://router.asus.com/Advanced_SettingBackup_Content.asp
2 - Choose one of the suggested methods above new setup 1 or 2 and connect your router to the internet.
  • setup 1 = OTN cable to > ac router wan port (once router is configured and internet is up) > new cable from ac router lan1 to ax wan > now move to step 3 configuring ax router to become AP
  • setup 2 = OTN cable to > ac router > now move to step 3 configuring ac router to become AP
3 - Go to your router settings page choose Administration under Advanced Settings > Operation Mode > choose Access Point(AP) mode / AiMesh Router in AP mode then > Save. http://router.asus.com/Advanced_OperationMode_Content.asp

  • Future upgrade is planned but we need to focus on the current situation.
  • AC86U can easily handle 400/400 connection . I tested ac68, ac88 and ac3100 and they handled 500/500 perfectly. I think ac86, ac88 and ac3100 will be fine dealing with 1024/1024.

  • You achieved speed and reliability by using ethernet which is best solution even if router can manage ax clients perfectly.
  • I prefer to connect devices using ethernet if I can hide the cable mess I create. :rolleyes:

Wirelessly, I have 3 streaming devices connected via wifi using the 5ghz connection. The cube gets 350DL/150UL, tivo 4k stream is at 120/120 and hisense TV running Google TV getting 220/180. This is on both the fios g1100 and Asus ax86u.

  • First I see you you are running "fios g1100" . I suggest you to return it specially if they are charging you lease fees on it.
  • If you are not paying monthly or comfortable paying for the isp router , you can use it to eliminate the slow wifi upload speed using my previous post.
  • You don't have a lot of streaming devices and you should be fine.

On the 2.4ghz network, I usually have 2 phones, 2 tablets, 2 chromebooks, a printer and a ring doorbell and 2 laptops. Not all at the same time, but a few at a time (probably 4 at a time along with 1 5ghz connection).

And the range was extended by about 20 to 30ft.

  • Here is my suggestion , I like one router to manage all connections coming in or out .
  • Connect all devices to asus routers and disable wifi from isp router or even better set the isp router to bridge mode if possible .
  • Disable asus router smart connect and let the devices decide for themselves under one one SSID.
  • You can set up 2 SSID's one for 2.4 and 5 . If the devices can't decide correctly.

But that upload speed via wifi on the close range is odd to me (it could be a device issue). And tbh, UL speed on those devices is less important than the wired server (which upload speeds seem to be fine wired).

  • I don't know what's causing just AX/AXE lines from asus limiting wireless upload speeds, unlike AC lines. My narrowed conclusion came to hardware that they can't address even with their newest routers or revisions.
  • I installed and tested other router brands with significantly lower specs and most of them achieved the isp advertised speeds wirelessly . Asus ax/axe routers can achieve the download speeds but not the wireless upload speed.

I suppose my question is, does the AC86u provide the same range as the AX and not have the reduction of UL speeds over wifi. At one point the g1100 had equal DL/UL and the 2.4ghz network had more range. But it's 4 years old and figured the age was just showing.

  • AX86 range is great for the size of the house it's placed high at the middle. I agree.
  • AC86 range is unknown to me ,but I if I can recommend another ac asus router I will pick ac88 or ac3100 because they gave me the same coverage as ax86 when tested + their fw support is still running from asus and merlin until now.
  • I tell people not to upgrade their router to WiFi 6 if there is no need or for it and stick with WiFi 5. Save the money for WiFi 7 (BE).

Not sure if I'm being unreasonable to think this router should allow for the equal DL/UL or not. At the end of the day, this ax86u will work fine, but if the AC86u can provide the same range and I can get equal DL/UL via wireless connection, I'd probably opt to return the ax86u and go with the AC86u...

  • You are not. Do not let router sales/public relations/fan boys reps get in your mind :cool:.
  • Have you ever heard about tech support tactics, same as sales. Some bad examples will blame anyone for their product malfunctioning or even better will come back with something like it's designed to function this way and it's a feature for a made up reason. They are trained to not admit any issue and divert your conversation somewhere else, that's if you don't give up from the long process.
 
If I may suggest, while the RT-AC86U was a fine unit "in it's day", it has a fairly nasty reputation at this point in time on the hardware reliability side: look around here, you will find lots of posts regarding the radios failing, as well as the voltage regulator, etc....at least in the long term.

RT-AC88U has it's own set of problems, mostly due to the extra built-in 4 port switch (Realtek) failing.
 
For me at least, AC routers are a no go as have an above 1 GB internet plan, so I need something with above 1 GB to plug that fiber line into to distribute in the home, or else it's bandwidth going to waste... Hence, I think have to go the AX router route.
 
How many of your devices can receive Gigabit over Wi-Fi and what they are going to use that speed for?

Understood, but my point is that if there are 5 people using itnernet in the house they have more bandwidth even if client limitations prevent realizing a gig or more wirelessly - am I understanding this right?
 
I understanding this right?

No. Wi-Fi serves one client at a time, most of the time. MU-MIMO to few clients is an exception, but rarely works efficiently in home environment and with mobile clients changing position frequently. Phones/Tablets don't need much speed, desktops and laptops might use higher bandwidth. Web browsing above 100Mbps ISP is all the same. Downloads and local transfers benefit from faster network. You mostly invest in higher speedtest numbers.

If you have 500Mbps ISP and a good AC router, increasing the ISP speed to Gigabit and replacing your router with AX won't change much your family's Internet experience. No one will notice any difference in common daily tasks. Make sure you have a good story to tell when asked why you needed to spend extra $300. Your wife perhaps doesn't know MB and Mbps. She will see the same things on her screen loading in exactly the same way.

In theory - yes, but only if you have >Gigabit WAN connection. How often you expect this scenario to happen? Also, keep in mind all home routers rely heavily on NAT acceleration tricks and any application with true packets processing will bring WAN-LAN performance down to 400Mbps or less.

Lately been noticing slow fw releases for ac88 compared to ac3100 . It may be related to the extra lan ports idk

If you have too, can afford it’s price and must be asus router then get ax89x

it’s the only asus ax router I tested that delivered full upload/download speeds + great coverage.

Personally I wanted to go with the ax89x but I can’t justify the price. I will wait for it go around 300, keep an eye on its fw development cycle, issues and revisions
