firmware m5 ตัวนี้สูงสุดแล้วเหรอครับ

เหอะๆๆ มันมาใหม่อีกแล้วครับ

AirOS V5.2.1-'a2 Released - 6/10/2010

- Show static routes in Main page, when operating in Bridge mode
- Station list is empty on IE browser
- Sometimes after FW update or reboot on AP, Station cannot associate with AP anymore (security ON)

V5.2.1-'a:

Official change log:

- Multicast enhancement on AP problems for multicast traffic (RSTP/OSPF doesn't pass wireless link)
- Multicast protocols traffic suppose to be sent as unicast to be retransmitted
- Multicast traffic floods entire office network
- Multicast packets in AP WDS - AP WDS setup are transmitted with 3 addresses
- IGMP proxy improvements
- CCR: Increase maximum allowed DHCP server lease time to 48h
- CCR: Allow more than 128 associations with security off
- AirControl Agent: Restore console reporting after wireless association is restored
- AirControl Agent: Report association time
- AirControl Agent: Odd behaviour with discovery response

MAJOR fixes:

- Wireless stability fixes
- WPA group key handshake failure
- AP is using the lowest TX rate (6Mbps), when communicating to legacy Stations and using WEP/WPA-TKIP/WPA2-TKIP security
- Incorrect data rates when operating in AP-WDS/AP-WDS and HT40 mode
- Incorrect frame type or subtype received from unauthenticated station (6)
- PPPoE client isn't restoring session after lost wireless link connection
- "MAC Address" change in Station-Router mode results WPA failure
- Devices behind STA-WDS in PtMP network, sometimes becomes unreachable
- Fix: SNMP: Report correct IF-MIB interface speed OID values
- Updated Australia regulatory rules according ACMA
- AP scans only upper or lower channels in HT40 mode
- AP(WDS) HT40 can connect AP(WDS) HT20
- GUI improvements
- GUI: Fixed rates uses SGI(400ns) rate table
