| + | The difference between routers sold in Russia and China and other version is flash size. Russian router has MX25L12845EMI-10G which is 16 legged SPI chip with 16M of NOR flash. It is sometimes marketed as WNR2200-100RUS, | ||
| + | |||
| + | However, as far as I can see, there is difference between labels on 100RUS and WW versions: Russian (16M) version has three fields with adhesive stickers: SECURITY PIN, SERIAL, MAC; While version sold elsewhere (8M) has four: WiFi Network Name (SSID), Network Key (Password), SERIAL, MAC. | ||
| + | It could be used as a clue, but this observation is based on only couple of routers and only definitive ways to determine fw size are via terminal or by looking at the chip itself. | ||
