Draytek and USB ethernet adapter

Anyone tried a usb to ethernet adapter on a draytek router?

Wondering if it's possible to hook up a second modem to my draytek 2860 via ethernet via usb?

It's in the loft so can't try just yet.
 
No, although I have tried an "EE Osprey" (the original one which is an Alcatel Link Y855) and that works fine using a DHCP mode. The speed isn't great but it might be handy as a backup.

I tried a different 4G modem (the original EE Buzzard - Huawei E8278) and the Draytek 2860 showed no interest in that at all so it might be limited to recognised devices. I believe that should also work using DHCP.

Both devices want to install a driver when plugged by USB into a PC.

If you do find an adaptor that works it would be interesting to know.

There is a list of 3g and 4g allowed usb devices on their website, anything not on the list will not work.
I'm aware of the list, I have an Alcatel L800.

But I'm curious if anyone has tried

I'm basically trying to be tight to avoid a dual ethernet wan router upgrade.
 
Well I stuck a USB memory stick in and it rejected it as it was not formatted fat32, so based on that the technology it can handle is old and would not extend to a ethernet adapter. So I suggest moving on or be the Guinea pig that wastes money not saves it.

My 2925 does allow the use of the wifi to connect to a phone hot spot and use that as an extra wan. That may be a route to go using a router with wifi if the 2860 also supports this which is does according to this as long as its got wifi.

 
@kommando828 gonna make you eat your words now.

Plugged in USB to ethernet adapter, picked up a device exists, plugged in a second router with live voda SIM and tadaa, it's picked up an IP.

Only slight issue is that I can't get the routing to work - there's no throughput which is weird.
I can't log in on the 192.168.1.1 address or ping either.

If the USB device is running a DHCP server and performing NAT, that makes it a router (with embedded modem), and not a simple modem.

I don't think it is?

the Draytek is picking up an IP address in the same range as the MF286D

It's basically Draytek USB -----> USB Ethernet -----> MF286D LAN1 port

If all other internet gateways are deactivated, a traceroute from a client will disclose which device is providing the route to the internet.

If I've got things the right way around, Draytek WAN4 has been configured for/as DHCP client and has obtained 192.168.1.2 by DHCP with the MF286D as 192.168.1.1 as DHCP server and routing out to the internet as a gateway.

I think a device only needs to route IP packets in order to be accurately described as a router.

I wonder if you are having the problem I had at first with my EE Osprey.

It is explained in this Draytek article:


I set the EE Osprey to work in the 192.168.100.xx range and that made it work, perhaps your second router (with the Vodafone SIM) needs a different LAN IP address range.
WAN4 is configured for DHCP client and obtained 192.168.1.2 which suggests something is working. The output says no cellular signal is established which does make me wonder how it would know that.

If the traffic on the MF286D could be dumped, it could probably be seen what IP address the device is trying to communicate on. I would probably wait a long time for a cellular connection to be made as that part should probably work regardless of what you connect to.

"The output says no cellular signal is established which does make me wonder how it would know that"
That's a general Draytek "feature":

From the linked article "Please note that the signal strength reporting is not supported in the 3.7.4.1 and support for this reporting may be added in a future firmware version."

Even with my EE Osprey the signal strength doesn't work, clearly it wouldn't with a USB to Ethernet adaptor. It did with a more basic 3G USB modem I had.

Does that link apply to the MF286D ?

My surprise was predicated on the USB to Ethernet adapter in place for which you've said "the signal strength doesn't work, clearly it wouldn't with a USB to Ethernet adapter" so we agree it would be surprising if it were to work as it needs to signal over the USB to Ethernet adapter. (It could do this by an appropriate protocol but I'm not aware of a suitable obvious such protocol.)

The MF286D works fine in the Draytek WAN port.

Ignore the 4G signal status bar, that only works with certain adapters, presumably those that present a PPP connection.

I'm trying to use the DHCP mode. Ive also got an L800 usb LTE adapter which does work fine.

I just couldn't believe the USB ethernet adapter worked in the first instance, that it was actually recognised and loaded, let alone managed to get an IP from the router.
disappointed though that it couldn't actually communicate, that I can't work out.
 
I am not eating them as its still not working ;) , try the wifi route.
Yeah, the 2862 has no WiFi. Got it originally to load balance a VDSL2 connection with it's built in modem and a 4G WAN but don't use the VDSL2 any more so might be time for an upgrade.
