At one point i had a troublesome device which would not let me connect to it with TFTP unless i put a dummy switch between the two devices. That might be worth a try.
You can use a router, but if it is handing out DHCP assignments, you need to be careful that none of them conflict.

Everytime I get " Connect request failed" And YES, TFTP is enabled in Win 10 and Win 7.
The reason WHY laptop in not "seeing" the router remains unclear. i tried it on 2 laptops Everytime the same reply" "connection failed" ??
Once i got stuck on a similar situation because I forgot to turn firewall off completely.
Have you tried wireshark to see if the router asks for anything?
Also, re-run the procedure checking step by step. I personally tend to make some very obvious mistakes when in theese kind of situations...

I tuned of the firewall--> it still does not connect.
Ping is ok.
re Wireshark: In the past I have had some really bad experiences with it including with Wincap -->So I don't install that anymore irrespective of where the download comes from.
Vistumbler v10.6.4 lists 27 AP's with signal strengths of 18% to 99%. on 2.4GHz
That just means the BulletM2 is not faulty, Now 'HOW TO MAKE IT CONNECT' is the million dollar question

I read through it. Very comprehensive: It would have been much simpler to just show a couple of wiring diagrams.
I have a couple of 4 pin & 6 pin ttl usb adapters in stock. No problems there.
But what I need to know is, if the 4 pins on the pcb are ttl or not. I prefer not to damage either unit at this stage.
#1 carries 3.3v , 2 is zero, 3 is 2.6v (probably Tx ??), 4 is gnd.
I cannot find any info for this online.

Back again...
I have Putty running on (Com12 115200 bps) the Bullet M2 via a FTDI232 adapter (connected in serial)
On hitting ENTER it shows : root@gargoyle:/#
For the rest it writes continuous lines like:
ar71xx_wdt_keepalive: 0xffb43480 ADR=b806000c
What do i put as a command to flash the new firmware eg : bs2m-webflash-firmware.bin ?

That would generally indicate to me that the device is fully booted and you're at the command prompt.
2 options from there.
Try to just reset the password:
Do a firstboot reset
