Firmware updates via USB and network

11-03-2012, 06:51 AM

When doing a firmware update on a wireless router, it should ONLY be done via a wired connection.
And with firmware updates via USB, the device should be DIRECTLY connected to the host (PC), not via a USB hub.

I think a number of update problems (even failures too!) are the result of not doing the above.

My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.

It's not the transfer method, it's the implementation.

Transfer is just transfer, nothing (but lack of memory or storage space for the new firmware) stops the firmware in the router to do a hash/crc check the determine if the firmware was uploaded correctly... before actually burning it permanently.
