USB WiFi Stick

I designed a router board, to use it in combination with the USB MT7610u stick
It was the smallest solution for Gigalan and Dualband.
From the tests everything was perfect, now MT7610U is no longer in production.

I bought all the dualband sticks that I found, but none are recognized.
Don't exist drivers, or I don't understand which driver does it require.

Can someone help me ?

RTL is a dead end, if you want to run them in AP mode.

yes, need AP
RTL is realtek ?
And only realtek made USB radio chip ?

Maybe exist MT7612U but is too big as board.


No, considering the ones you got linked to, were MediaTek and Atheros.

Try scrolling to the bottom on that list.

|Chipset|Interface|Standard|MIMO|2.4|5|6|Linux In-Kernel Driver|AP Mode|Monitor Mode|

But on this list, this information are also good for OpenWRT ?

Realtek RTL8811cu says AP is ok

Mediatek and Atheros should be OK ...

Well, apparently they're not very trustworthy ?

I have ordered AR9271 from amazon.
If work well there are smaller version on china:

thanks for the moment

Hi, is this working well ?

I haven't tried it yet.
I'll try it next week.
I believe this model is not AC

ar9721 is 802.11n and 2.4 GHz only, while the ath9k_htc isn't bad, it's unsuitable as AP (not reliable, weird connection stalls, 4 (or 8?) connected clients at most). It doesn't make sense to buy an almost 10 year old device today.

Thanks showed my error.
I need dual band, very small, AP for one client only.
I have not found any alternative to the MT7610

Hi gioreva,

The mt7610u chipset is definitely still in production. I use an adapter with a mt7610u chipset with my OpenWRT setup. I'm going to repost the link provided earlier in this thread:

That is the Main Menu. If you go to menu item 2 and scroll down to the section on the mt7610u chipset, you will find several adapters based on the mt7610u.

It might help if you explain in more detail what you mean by "very small". The Linksys AE6000 is very small. I have one. It works well and it is very small. It is only slightly bigger than a nano size adapter.

The mt7610u adapter that I use with my OpenWRT setup is the ALFA AWUS036ACHM. The size does not matter in my case because it comes with an extension cable so I can place it where I want. This adapter has astounding range.

If your use case could work with an extension cable, then you might even look at an adapter based on the new mt7921au chipset (WiFi 6e). The driver is in 22.03... 7921u, however the firmware is in the driver 7921e so you either have to also install 7921e or manually install the firmware. There is a bug posted requesting the firmware be moved to common so this will likely be fixed at some point.


This my board. Green is usb MT7610U

I'm sure.
The chip is no longer in production.
I have asked many China chip suppliers.

I found a last stock of 50Kpcs
But they are very expensive, I can't stock for many years.

Check on Amazon
Linksys AE6000 out of stock

AliExpress 25/40 USD

It may no longer be in production by the Chinese copycats but it is in production. That doesn't matter if you can't get chips so our discussion on whether it is in production does not currently matter. Mediatek is still producing chipsets as far back as the rt5370 single band chipset. They have retired the re3070 and rt5372 within the last year. Being a fabless company has some downsides. I saw where Mediatek signed a contract recently with Intel for using Intel fabs to produce Mediatek chips so maybe we will see a more consistent supply of chipsets from Mediatek going forward.

Interesting board you have there.

Board for this device:

Then, maybe, if I stock for one year, I will find chip?
So many complex chip can be cloned?
I think only simple chip.

If you don't answer here I open a new post.

New build, last OpenWRT version.
USB radio MT7610U

The Windows PC connects correctly, everything works well.
Smartphone Android connects but without the internet.
DHC from ETH provides correct IP on the phone.
Even setting the phone with static IP/gateway/DNS, it does not reach the Internet.
