After being very happy with my WNR2500L in my Australian office, I recently purchased another for my Philippines office. This second one happrened to be a WNR3500L v2, so I opened both up to see what the physical differences are.
Here are the results:
| WNR3500L v1 | WNR3500L v2 | |
| FCC ID | PY308400093 | PY310400153 |
| Power | 12VDC 1.0A | 12VDC 1.5A |
| CPU | Broadcom BCM4718A1 | Broadcom BCM47186B0 (480 MHz) |
| FLA | 8 MB (Macronix MX25L6405DMI-12G) | 128 MB (Samsung K9F1G08U0D) |
| RAM | 64 MB (Samsung K4T56163QI-ZCE6) | 128 MB (Winbond W971GG6JB-25) |
| Expansion | 1 x USB 2.0 | |
| Wireless Chip | Broadcom BCM4718A1 | Broadcom BCM47186B0 |
| 802.11 Protocols | bgn | |
| Antenna Connector | None | U.FL |
| Ethernet Chip | Broadcom BCM4718A1 | Broadcom BCM47186B0 |
| Switch | Broadcom BCM53115 | |
| LAN Speed | 10/100/1000 | |
| LAN Ports | 4 | |
| WAN Ports | 1 | |
If you are not sure which version of the WRN3500 you have, check the FCC ID number on the rear of the case and compare it to the above.
Do you happen to know if for the WNR3500L v2 / BCM47186B0 switch chip if any VLAN Id can be used as I've read previously with DD-WRT the VLAN ID's shown are only 1-15 like the Dot1Q VLAN ID field is only 4 bits but the 802.1q standard permits 1-4092 with the exception of about 5 ID's for token-ring of Ethernet ID's.
