[closed] networking via hub & speed issues

EDIT: silly me! Confused bits and bites! Got new problems though with a newly bought switch. Opening another thread for that one ...

Hello everyone

My setup is the following:

* Arch Desktop connected to wired network.
* Debian (testing) Laptop connected to the same network within the same segment

* They are connected via a hub

Issue: When I'm transferring data via ssh/scp/rsync the speed is only up to 1Mb/s.

Arch machine:

#  ethtool eth0
Settings for eth0:
	Supported ports: [ TP MII ]
	Supported link modes:   10baseT/Half 10baseT/Full 
	                        100baseT/Half 100baseT/Full 
	                        1000baseT/Half 1000baseT/Full 
	Supported pause frame use: No
	Supports auto-negotiation: Yes
	Advertised link modes:  Not reported
	Advertised pause frame use: No
	Advertised auto-negotiation: No
	Speed: 10Mb/s
	Duplex: Half
	Port: MII
	PHYAD: 0
	Transceiver: internal
	Auto-negotiation: off
	Supports Wake-on: pumbg
	Wake-on: g
	Current message level: 0x00000033 (51)
			       drv probe ifdown ifup
	Link detected: yes

Debian machine:

# ethtool eth0
Settings for eth0:
	Supported ports: [ TP ]
	Supported link modes:   10baseT/Half 10baseT/Full 
	                        100baseT/Half 100baseT/Full 
	                        1000baseT/Full 
	Supported pause frame use: No
	Supports auto-negotiation: Yes
	Advertised link modes:  10baseT/Half 10baseT/Full 
	                        100baseT/Half 100baseT/Full 
	                        1000baseT/Full 
	Advertised pause frame use: No
	Advertised auto-negotiation: Yes
	Speed: 10Mb/s
	Duplex: Half
	Port: Twisted Pair
	PHYAD: 1
	Transceiver: internal
	Auto-negotiation: on
	MDI-X: off
	Supports Wake-on: pumbg
	Wake-on: d
	Current message level: 0x00000001 (1)
			       drv
	Link detected: yes

Hub: etherperfect 505st (pdf)
So it should support 10M ...

ssh via wlan (passing by the router): Gives me more or less the same connection speed as via hub.

So my thinking right now is that maybe it's because its a hub and not a switch? Then again I don't know nuts about networking ... So before just buying and trying I thought I could ask

Thanks in advance!
