| + | ==== Support status of the gigabit switch ==== | ||
| + | |||
| + | For a very long time, the gigabit switch did not work properly in OpenWrt for some versions of the SoC (see [[# | ||
| + | |||
| + | As of March 2020, this is now fixed in [[https:// | ||
| + | |||
| + | ==== Hardware differences with RB951Ui-2HnD ==== | ||
| Sister product: [[http:// | Sister product: [[http:// | ||
| The RB951**G**-2HnD differs from its sister board RB951**Ui**-2HnD in that it has 5 * GigE instead of 5 * FE ports. The 5 GigE ports are provided via an AR8327 GigE switch chip that is also used in larger routers such as the RB2011-UiAS-2HnD-IN. The 5 FE ports on the RB951Ui-2HnD are inside the AR9344 SOC, they are unused/ | The RB951**G**-2HnD differs from its sister board RB951**Ui**-2HnD in that it has 5 * GigE instead of 5 * FE ports.

| - | On the downside, as of 11/2015, the OpenWrt support for the internal GigE port on the AR9344 connecting to the AR8327 is the problem why an additional patch to OpenWrt is required that is not needed for the RB951Ui-2HnD. | ||

| + | If after installing on a rev 2 device the switch seems to drop packets, you may be able to work around this by holding the reset button during power-on. This delays booting giving the switch more time to initialize. This issue is not noticed during a PXE boot, only after an install to flash. | ||
| + | |||
| + | === Kernel module === | ||
| + | A kernel module for OpenWRT 18.03.1 wich embeds the fixup code exists: https:// | ||
| + | |||
| + | The source code is available here: https:// | ||
| + | This kernel module permits to use the original (not patched) kernel from OpenWRT. | ||
| + | The module can be transfered with the serial port of the router (soldering needed!). | ||
