Hi guys,

I'm currently using this configuration

========
Model    Hewlett-Packard HP ENVY 6 Notebook PC  + TPLINK TL-WN722N
Version    OpenWrt Designated Driver 50104 / LuCI Master (git-17.085.52855-65a089d)
Kernel      4.4.14
========

So the main purpose for using this kind of setup is    --->  VPN.
It's using ethernet port to connect with ISP, and sharing encrypted traffic over the WiFi with USB TPLINK.

it seems that I'm so much limited by 2.4 Hz bandwidth, as a result I was trying to look for 5Hz WiFi-USB which is supported by OpenWrt.....Unfortunately I cant find it.

I need ur advice here, guys!

#1. Does anyone successfully use 5Hz WiFi with Openwrt? Is it possible? If so, with which model?

#2. I could also connect  end-client with ethernet , but the problem is that the only ETH port on Openwrt
          is busy with ISP cable....and I have no idea how to configure this setup.
          Is it possible?

Hey there.

I can give you some details about number two.

Currently your HP device has eth0 connected to your ISP for both, hardware and software.

For the software part, you can use eth0.2 instead of eth0, which means you're using vlan 2 wan. Use caution, adjusting this setting will make your HP device stop using the ISP uplink. That's intended and will be solved by adjusting the hardware. But make sure you can physically access your HP device and use a local keyboard for configuration and potentially reveting this.

For the hardware part, you need vlan aware switch, like e.g. the D-Link DGS-1100-08. Make one port "tagged vlans 1 and 2", one port "untagged vlan 2" and all the other ports "untagged vlan 1". Now connect the ethernet port of your HP device to that "tagged" vlan ports and your ISP router to the "untagged vlan 2" port of the switch.

That's basically the same configuration a SoHo router with integrated switch has. I do run this setting myself, except that I don't use an old laptop but a BananaPi M1. But there's no difference to wiring, I too have a router with only one ethernet port being connected to an external vlan switch.

So yes, it is possible.

As far as I know, there aren't any USB 802.11ac adapters with open drivers for OpenWrt or Linux in general.  A dual band a/b/g/n adapter with Ralink chip will work.  The bandwidth of 802.11ac exceeds USB2 anyway though.  Does this PC have a PCIe slot for a wifi adapter, and will the BIOS let you use any adapter?

USB to Ethernet adapters exist.  You can also press almost any old router that runs OpenWrt into service as a managed switch.

Hi there guys,

At first, I want to say big thanks for your answers and advices. I really appreciate this!

I have TL-SF1005D, could it do the same job? IF so, how could I configure those VLANs you mentioned above? I cant find any web interface or configuration page...

Hey there.

You need a switch that can handle vlans and is managable. The TP-Link SF1005D is not one of them.
I know there's the TL-SG105E, but since they cannot reassign vlan ID 1 but always map vlan ID 1 tagged on all ports, I'd recommend to not use TP-Links.

The cheapest ones I know are the D-Link DGS-1100-xx.

Having a switch that has no configuration page, or has at least no configuration page mentioned in its documentation, most likely cannot handle vlans and cannot be managed.

Do you think all TP-LINK have this problem with VLAN ID?
I'm going to purchase one, and while comparing the DLINK you mentioned and this TPLINK - http://www.tp-link.com/us/products/deta … 2008.html,

I found that TPLINK  is more configurable, so could you please confirm that this model will NOT work with your kind of setup.

Thanks!

I can't tell you anything about the SG2008. I only tried a SG108E a couple of years ago.

Both, the TP-Link SG108E as well as the D-Link 1100/08 are both around 35€, the TP-Link SG2008 is nearly twice the price. So I'd expect it to be somehow better in a certain way.
But to be honest, I didn't look in that particular price range. I even didn't look into any price range at all, I just got my TP-Link SG108 when it was on sale for less then 30€. So I decided to take it. What could possible go wrong.
Despite the 108E not being that configurable I kept it nevertheless, because I figured it wasn't the sellers foult of not having me informed about the capabilities of that device but mine of not having done enough research and reading.

Being able to SSH into the router, which is possible for the 2008 according to its documentation, seems like a nice feature. So maybe go for it and try.

Stephan.
