I want to set up a temporary openvpn router using a 10 year old i5 laptop.
I've downloaded x86 64bit squashfs image using the firmware selector and wrote it to flash drive with Rufus. OpenWrt 22.03 boots up and I can access the laptop via gigabit LAN port and download packages. But there is no WAN port.
Can anyone recommend which USB3 gigabit LAN adapters known to work with OpenWrt x86, sold in UK ?
@M10 Interesting solution. I don't have a managed switch to hand. I do have spare MT7621 and HH5a (Lantiq) routers running owrt which could be a suitable substitute? I would just need to find instructions on how to configure the VLANs etc.
As @trendy says, get the UE300. Been running one as my WAN connection on a RPi4 for a few years now without a single issue. Been rock solid. And you can get one for less than £14 from Amazon at the moment.
ok, I thought I'd try @M10 suggestion, by using a spare HH5a as a managed switch.
I'd been avoiding it for years as I prefer swconfig. After completing a crash course in DSA and VLANs (ie. studied the openwrt mini tutorial), I managed to get openwrt on the laptop working as a wired router, with the HH5a 'switch'.
When I ran a speed test, sadly the test hung while reporting 320 mbps and didn't complete. Openwrt console on the Dell Latitude e6530 intel 3rd gen laptop threw up the following error amongst other cryptic diagnostic info during the speed test.
You can get some Mini PCI-e card (with multiple ports) and install it at the WiFi slot. Also, there could be some slot like M.2 with PCI-e lanes, usable with an adapter. The firmware of the laptop, however, may accept only whitelisted devices.
The ports of the Mini PCI-e cards are with extension cables, not directly over the card. It will be far more stable than any USB if having a well supported chip. I remember that you can easily remove the optical drive of these with one click. So there will be space for several ports without drilling. I do not remember if the docking port had a separate Ethernet PHY or it was redirecting the RJ-45 port.
The interesting part is that the laptop possibly has an ExpressCard slot over the optical drive, but I never managed to get its cover loose, like the optical drive itself... The ExpressCard is about $30 for a gigabit one, there are even some with two ports.
