| [wired] What is an "uplink" port (BEFSR41v2)?
The Router that I got from a thrift store, and which seems to be working great, a Linky BEFSR41 Version2, has a WAN port, 4 LAN ports, and also an additional "Uplink" port.
Can someone tell me how the uplink port works, why it is there, and if I can use all the other ports at the same time with it?
Also, a second question:
How secure am I with this router? I ask because this is such a common router that I worry that many have found ways to get around the firewall and can use exploits on it...
TIA, Very Much!

somewhere | Uplink port is actually connected internally to port 1 or 4 (don't remember) with internal crossover cable. So you cannot use Uplink port and port 1 (or 4) at the same time. You can find it in the manual. |

I don't have a manual, I guess I will have to see if there is one online or something. Still, is it a way to link to other Switches/Hubs? I am assuming that maybe it changes what type of cable I use too? |

1 edit | An "uplink port" is used to "daisy chain" switches and bridges. It is simply a port which is wired to act as a crossover cable, so that you don't have to have a crossover cable to go from a standard port on one switch to a standard port on a second switch.
Lets see if I can say that another way. There are two ways to wire an RJ-45 connector. One is called "straight thru" and is used to connect a computer or other similar equipment to a normal port on a hub or switch. The other is called "cross over" and is used to connect a hub/switch to a hub/switch using the normal ports on both devices. The need for a cross over cable is eliminated by the uplink port. The uplink port is used to "daisy chain" switches and hubs. It exists simply to make your life easier.

| Thanks, thought that might be the case. What I am disappointed is that it takes away one of my 4 LAN ports if I use it.
I wonder why it was eliminated on the Ver3 (current version) BEFSR41 router device. Could it be that it is automatic on the new one? Is such a thing possible?

Lots of devices are starting to turn up with autonegotiated port arrangements. It is quite likely that it has been eliminated for the reason you suggest. You could test the theory with a cross over cable and a straight thru cable.
I don't know whether it will take away one port or not. The easiest way to check it out is to see if you can use both the uplink port and the one beside it at the same time.
Usually if the uplink port ties up a normal port the link light for that port should light up when there is something in the uplink port.

Yep... Current Data sheet says "Autmatically detects straight or cross-over cables". Which implies that any port can act as an uplink port automatically.

| I have the linky befsr41 ver2. If you use the uplink port, you can not use lan port 1. I have never had a problem with anyone getting thru the router to my systems, that I know of. Just make sure you change the default password and disable remote admin., so no can change the router settings from the wan port.
Hope that helps. |
