Looking at the design of the RT2600ac
The Synology RT2600ac comes with four detachable antennas. The body itself is made of plastic with matte black finish. Most of the router’s surface have ventilation slots for passive cooling. This is great as most routers nowadays run a little hot/ warm to touch.
On the front edge of the RT2600ac, you will be able to find a full-depth SD card slot on the left. It allows a normal-sized SD card to be inserted fully into the slot. This is unlike the half-depth SD card slot found previously in the Synology RT1900ac where half of the SD card sticks out of the router. On the right is where you will find the model number of the router – RT2600ac.
On the left edge of the RT2600ac is where the USB 3.0 port and (storage) eject button are located. The eject button has a LED indicator on it to display the status of (attached) storage media(s).
On the right edge of the RT2600ac are the buttons for toggling WiFi connectivity (switching on/ off WiFi) and WPS. The LED on the WiFi button will be lighted up when WiFi is enabled.
On the back edge of the RT2600ac are the power button, power port, reset button, USB 2.0 port, WAN port and LAN ports. One point to note is that the LAN-1 can be reconfigured to become WAN-2 for active-active or active-passive WAN support.
As mentioned earlier, the antennas are detachable so the stock ones can be replaced with higher gain antennas if required.
On the base of the RT2600ac are the mounting holes, (more) ventilation slots and the usual sticker with product information.
The pointed stand at the top corners of the RT2600ac (in the above picture) are no longer removable like the ones in RT1900ac. With the non-removable (pointed) stands, I am not sure how I can mount the Synology RT2600ac to vertical surfaces like walls or cabinets. There are also no mounting brackets included in the package.
Previously for the RT1900ac, there is an additional stand that can be attached to the router (via the mounting holes) to allow the router to stand upright like in the picture above. Perhaps Synology can include a stand to allow the RT2600ac to stand upright on tabletops.
Lastly, the RT2600ac is physically bigger than the RT1900ac. The RT2600ac would take up a fair bit of table space considering that it cannot be placed upright like the RT1900ac.
