VLANs on bridges, or bridges for VLANs?

Hello! I just started working with vlans on routeros and, guess what, I have questions! Consider this scenario: a routerboard with say, 5 eth ports. On 4 of them I want to make 3 vlans available . Should I bridge the ethernets together and then create 3 vlan interfaces on the bridge interface or cre...

Re: NetMetal 5 bandwidth-test

Could it be that the radio is overloaded, is producing noise or the standing wave level is high (http://www.radiomagonline.com/misc/0082 ... nnas/26360)?

I would try reducing power. 66dB SNR is overkill.
