Hi everyone,
I have a 411UAHR RouterBOARD + MC8705 wireless module + R52Hn MiniPCI card installed.
I use this setup for internet and networking at my home office. I use a number of devices on the network and some devices like printers and phones only support 2.4Ghz 802.11g and others like the iMacs support 5Ghz 802.11n. What I want to do is provide 5Ghz 802.11n for the iMacs while still providing 2.4Ghz for the older devices. The reason I want to do this is so that I can take advantage of the faster 5GHz 802.11n to add NAS storage for backups.
I want to configure the onboard WiFi radio to work at 2.4Ghz 802.11g and the R52Hn at 5GHz 802.11n.
The 2.4GHz WiFi and Ethernet works as expected and internet connectivity is working just fine.
However on the 5GHz WiFi the DHCP server doesn’t lease an IP to the computers and if I manually enter the IP, gateway and DNS on the computer there is still no internet connection.
Here is the configuration as done through the WebFig interface:
wlan1 = 411UAHR onboard Wifi
wlan2 = R52Hn
ppp-out1 / lte1 = MC8705
Initial Setup:
“Quick Set” →
- “Mode” = Bridge
“IP Address” = 192.168.0.1/24
“Country” = South Africa
“System” → “SNTP Client” →
- “Enabled” = true
“Mode” = unicast
“Primary NTP Server” = 41.73.38.11
“Secondary NTP Server” = 41.134.20.28
“System” → “Clock” →
- “Time Zone Name” = Africa/Johannesburg
“System” → “Users” → “admin” = {Change admin password}
Bridge Setup:
“Bridge” → “bridge1” →
- “Name” = Bridge
“Protocol Mode” = rstp
“Bridge” → “Ports” → “Add New” →
- “Interface” = ether1
“Bridge” → “Ports” → “Add New” →
- “Interface” = wlan1
“Bridge” → “Ports” → “Add New” →
- “Interface” = wlan2
DHCP Setup:
“IP” → “Pool” → “Add New” →
- “Name” = DHCP Pool
“Addresses” = 192.168.0.25-192.168.0.254
“IP” → “DHCP Server” → “Add New” →
- “Name” = DHCP Server
“Interface” = Bridge
“Address Pool” = DHCP Pool
“IP” → “DHCP Server” → “Networks” tab → “Add New” →
- “Address” = 192.168.0.0/24
“Gateway” = 192.168.0.1
“IP” → “DHCP Client” – “Add New” →
- “Interface” = lte1
NAT Setup:
“IP” → “Firewall” → “NAT” tab → “Add New” →
- “Chain” = srcnat
“Out. Interface” = lte1
“Action” = masquerade
Interface Setup:
“Interfaces” → “wlan1” Wireless (Atheros AR5212) →
- “Enabled” = true
“Name” = WiFi Onboard
“Mode” = ap bridge
“Band” = 2GHz-only-G
“Frequency” = 2462
“SSID” = Mikrotik 2.4GHz
“Wireless Protocol” = unspecified
“Interfaces” → “wlan2” Wireless (Atheros 11N) →
- “Enabled” = true
“Name” = WiFi Card
“Mode” = ap bridge
“Band” = 5GHz-only-N
“Channel Width” = 20/40MHz HT Above
“Frequency” = 5180
“SSID” = Mikrotik 5.1GHz
“HT Tx Chains” = chain0 + chain1
“HT Rx Chains” = chain0 + chain1
“Interfaces” → “ppp-out1” →
- “Enabled” = true
“Name” = PPP
“Dial On Demand” = false
“Interfaces” → “LTE” →
- “Enabled” = true
“Name” = LTE
Wireless Security Setup:
“Wireless” → “Security Profiles” → “default” →
- “Mode” = dynamic keys
“Authentication Types” = WPA PSK + WPA2 PSK
“Unicast Ciphers” = tkip
“Group Ciphers” = tkip
“WPA Pre-Shared Key” = {Enter encryption key}
“WPA2 Pre-Shared Key” = {Enter encryption key}
“Wireless” → “Connect List” → “Add New”
- “Interface” = WiFi Onboard
“Wireless” → “Connect List” → “Add New”
- “Interface” = WiFi Card
Final Setup:
“System” → “Shutdown”
{Disconnect Power}
{Reconnect Power}
