hi guys, I have Dlink 2750u, i connected Transcend 16gb USB drive to it and can can access that via LAN and I've mapped as network drive too :-D speeds are 3MB/s
From lan, I can access it from \\192.168.1.1\myname
Even though I've setup password it does NOT ask for password!!!
==============================
in "Storage service > User Accounts"
User name: somename
Password: somepassword
Confirm Password: somepassword
volume Name: usb1_1
==============================

I can access router management page from *somename.dyndnsorg
I get username and password box if I type ftp://myusername@somename.dyndns.org, I get a window asking username and password but its not logging in even if I enter correct details...
I'm doing this from WAN, not from LAN, a computer from another place

In the Access Controls page, click Services & make sure ftp is enabled for WAN.

if you meant it is currently in use then try when this folder/usb is not accessed by any pc from lan.

are you using a pc/laptop with firewall(or behind a router) to access the ftp?i am assuming that pc/laptop you are using is not connected to 2750u.if yes then disable firewall/remove router & then try.remove the port forward setting first.

LOCATION 1: PC<=>BSNL (WA3002G4)
LOCATION 2: PC<=>BSNL (DLINK 2750u)

port forward works, i've tested it with online checking tool...

remove port forward rule/go back to original config before port forwarding.configure the modem in bridge mode & disable the pc firewall on the pc from which you are trying to access 2750u.if this is troublesome then use a gps/3g connection on the pc to access 2750u.

Bridge mode??? I have multiple computers and so the modem is is auto connect mode (bsnl user and pass entered in broadband, no need to dial manually)
btw how to check ftp on android web browser(Dolphin)
will check tomorrow, happy new year!!!

^^you tried this from a gps/3g connection?as a last resort just to rule out anything from modem side configure wa3002 in bridge mode,disable pc firewall & then dial connection from pc 1 to connect to net.if still no success then try no-ip instead of dyndns like in my post#2 link.you can also pm @Rajesh345 to know what exactly is difference between your way & his way of asus rt-n13u.

P.S.my net connection was down & hence the late reply.

I'll try via USB tethering the 3G connection...and my Broadband (Dlink 2750u ) doesn't support no-ip only dyndns, and i cant install dd-wrt on that...:cry:
but i can connect via ftp to other sites, like driveHQ, etc....
not able to login my router usb port's storage ftp site, idk why...

i messaged him....
