Slow WLAN Box 2 speed

PaddyG

Hi all,

My home set-up is the following: 500 Mbps speed with Internet Box 4 in the basement connected via Cat 6A cable to 2 WLAN Box 2’s on the ground floor and 1st floor. The wireless speed with the ground floor WLAN box is fine, close to 500 Mbps. However, the 1st floor wireless speed is only 100 Mbps or less. If I connect my PC directly to the 1st floor ethernet, it returns to 500 Mbps but if I connect the PC with ethernet through the WLAN Box, it goes back to 100 Mbps. So, there is no issue with the ethernet speed at the wall, but the WLAN Box seems to slow it down, whether it is wired or wireless.

Any ideas? Thanks.

@PaddyG Could please switch the two Wlan Boxes, if it is a problem with the Wlan Box, the first floor Box should also do the same when installed in the ground floor.

Hi, thanks for the suggestion. Of all the “easy” troubleshooting I could have done, this is the one I forgot completely. I switched the 2 WLAN Boxes and the 1st floor speed didn’t change and even the ground floor speed dropped to < 100 Mbps.

Try reducing the transmission power to 50%. Looks like the clients are connecting to the wrong WLAN-Box.

PaddyG

I don’t think that’s the problem, according to the network topology, it’s connecting to the correct box. How do you reduce the transmission power anyway?

It could be a problem with the cables. Maybe the crimping or the cable itself is faulty.

PaddyG

Nope, tried different cables and still the same. As I said, if I connect my PC directly to the wall

Ethernet port, the speed is fine. It’s only if it goes through the box, either wired or wireless.

@PaddyG In that case, I’d call the hotline 0800 800800 and insist to speak with the 2nd level support, as this is quite strange an they can check the system remotely.

The fact that it drops to exactly 100Mbps makes me think that it gets limited to fast ethernet speeds. It can only happen if the differential leads in the cable are not all properly connected. Either that or it connects to an access point that is further away.

I don’t believe it’s an issue with the WLAN-Boxes, but this is also something to verify.
