The signal strength seems good in any case, and placement of the client relative to the access point seems not to make any difference. In all cases, I have 30-50dB over the noise floor.
I'm new to the Mikrotik forums, so I'm not sure what the most relevant information to provide is, but I'll start with a printout of my wireless interface:
[admin@MikroTik] > /interface wireless print Flags: X - disabled, R - running 0 R name="wlan1" mtu=1500 mac-address=4C:5E:0C:C4:EB:0B arp=enabled interface-type=Atheros AR9300 mode=ap-bridge ssid="creampuffstarship" frequency=auto band=2ghz-b/g/n channel-width=20/40mhz-ht-above scan-list=default wireless-protocol=802.11 wds-mode=disabled wds-default-bridge=none wds-ignore-ssid=no bridge-mode=enabled default-authentication=yes default-forwarding=yes default-ap-tx-limit=0 default-client-tx-limit=0 hide-ssid=no security-profile=default compression=no
Things I have tried:
1) I have attempted just b/g, thinking it was a compatibility issue of my client devices with N (no such luck)
2) I have changed frequencies - I tried several fixed frequencies, including one or two that I found to be unused in any of the networks that are visible from the router. I ultimately settled on "auto" as the safest bet, but it doesn't appear to make a difference in any case.
Any thoughts? I feel as though it has to be something silly I'm doing.
