Thanks Seet. Actually now Atheros is the No.1 Wireless chipset provider worldwide. TL-WR841ND V7and TL-WR841N V7 is using the same chipset as i know for sure.
I think haven't started yet, at least I don't feed any slow down on uTorrent yet!
If I'm not mistaken, the ND was previous product range, removable antennas, square look with rather big LED lights in front.
The N is latest product range with more modern look, irremovable antennas, nicer LED lights on top.
If I'm not mistaken, the 841N v7 is on Atheros AR7241@400 4/32MB platform with AR9287@20dBm 2x2 MIMO WiFi NIC
DIR-615 has so many variant, the TM's Gx range seem to be based on D1 range, which is on Ralink RT3052F@384 4/32MB platform with Ralink WiFi NIC only, definitely no MIMO.
So I'm quite sure the 841N v7 is better than DIR-615, especially the WiFi.
I was told and read somewhere that generally, Broadcom & Atheros chip is better than Ralink. Atheros seem to be more open to release drivers for developers whereas Broadcom sometime not so open.
Broadcom used to be the "boss" initially, than Ralink & Atheros, now Atheros seem to be the "boss" in the market, battle continue and "boss" keep changing during the race .....
My personal experience, I prefer either Broadcom or Atheros, Ralink runs good on dd-wrt but generally not on factory stock firmware.
Broadcom is more expensive than Atheros & Ralink.
The current custom beta firmware only for TL-WR841N ver7.
Yes, the price is really affordable below RM100 !!

UniFi belongs to Telekom and Telekom OPENLY advertise publicly by saying all calls to TM's fixed line is free.
If it's overseas, I'm very sure consumers already file class suit action against TM.
We Malaysian are just too kind to them, and our MCMC is either sleeping or never bother to regulate.
It may not be the money that concern, but it's the way how a so-called national ISP dare to cheat public at large by adopting such immoral yet dirty business tactic.

I tested and the firmware can be used for TL-WR841ND v7 also.
Hi KLseet,
Thanks very much for the helpful info at klseet.com and it's great to know of alternatives to the D-Link 615. It's pretty unstable (Wifi keeps d/c) for my iPad and iPod Touch (despite playing around with the settings eg b/g vs bgn) so that's why I am keen to try another router.
I notice there are two variations of the wireless router: TL-WR841N and TL-WR841ND. Do you know if the beta firmware will work with the TL-WR841ND as well?
The price is quite affordable and worth the experiment to see if it provides a better Wifi experience than the D-link.
Cheers
