Η διοργάνωση αυτή αποσκοπεί στο να συγκεντρωθούν άνθρωποι απ’ όλον τον κόσμο και να δοκιμάσουν την απόδοση διαφορετικών πρωτοκόλλων δρομολόγησης […]
Το Bullet2 είναι ένα AP/Bridge χτισμένο γύρω από το AR2316 SOC της Atheros. Ο επεξεργαστής του είναι τεχνολογίας MIPS 4Kc και χρονίζεται στα 180MHz. Επίσης διαθέτει ενσωματωμένο ασύρματο και 10/100 Ethernet MAC.Bullet2 is an AP/Bridge build around Atheros AR2316 SOC. Its CPU is based on MIPS 4Kc technology with a […]
Firmware Modification Instructions Unarj some_firmware.bin (is actually an arj archive) Modify NML.MEM image Arj NML.MEM back to some_firmware.bin Pad zeros to end of some_firmware.bin until it reaches size 0xe0000 Copy hardware version string starting at address 0xdffe0 Compile dwl_checksum.c: gcc -o dwl_checksum dwl_checksum.c Calculate 32bit checksum: dwl_checksum < some_firmware.bin Copy […]
With this modification you will be able to control the power output of any device that uses GL2422MP miniPCI wireless card in a range from -13 to 17dbm on AP mode and -11 to 19dbm on the other modes. Some devices that use Global Sun’s GL2422MP miniPCI is D-link DWL-810+, […]
Improvements Antenna selection remains the same for both RX and TX More TX power control settings (1 – 18dbm) Power control works on all modes Additional channels (12, 13 and 14) Better web interface Screenshots
