Model: EAP225-Outdoor  
Hardware Version: V1
Firmware Version: 1.6.1 Build 20191022 Rel. 41405

Hi there,

 

I bought four EAP225-Outdoor(EU) devices. One of them is connected via LAN to my FritzBox 6591 Router.
My internet connection is 1Gbit Download and 50Mbit Upload. I can reach this speed without problems via LAN cable that is connected to my FritzBox.

The other three EAP225-Outdoor(EU) devices are connected via Mesh network. 2Ghz and 5Ghz networks are actived.
The devices have direct intevisibility (nothing between them like walls or other stuff) to each other and the distance is maximum 20 meters.

When I connect my PC or smartphone via 5Ghz to one of the EAP225-Outdoor(EU) I have a maximum bandwith of about 105Mbit download (sometimes 120Mbit) and 50 Mbit upload.

As the EAP225-Outdoor(EU) supports 867 Mbit maximum I expected to have at least like 500-700Mbit, because of the good connection.

I'm pretty sure I configured sth wrong, perhaps somebody has an idea what to do here?

Cheers

Thomas

Hi @Thomas83,

 

Just to clarify, are you saying that when a wireless client (like your mobile) is outside, connected to one of the outdoor wirelessly meshed AP's (which are uplinked to the hardwired root node through the 5.8GHz radio) you're seeing roughly 105-102Mbit/sec DL on you mobile?

 

Unfortunately, this is normal.  I just made a similar observation myself.  I get up to 150 Mbit on my wirelessly MESH'ed EAP225-Outdoor -- it's uplinked to an Ethernet connected EAP225V3.  I have Gigabit fiber internet (both directions are gigabit).  But I only have one wireless MESH AP, which is why mobile is a bit faster -- less chatter than you have with 4 outdoor AP's.

 

The problem is that the "goodput" is only ~50-60% of the air link speed for each hop.  What I believe you describes is two hops -- like I have.  STA to Outdoor AP, Outdoor AP to hardwired AP.

 

so even if all air links were 866MBit/sec.  That would be:

 

866 * 0.5 =  433 (in practice I get more like ~450 max) for the first hop.

And then 433 * 0.5 = 216.5 (in practice I get more like ~150 max) for the second hop.

 

Because all of the MESH clients (AP's and their Wifi connected STA's) chatter on the same frequency, there's a lot of overhead back and forth which limits the throughput.  And the negotiated air link rates are rarely 866.
