Good shout on the 0.1inch header, got one from Maplin for 1. Garbledness seems to be ok now.

I wouldn't mind having a copy of your pre-cut images if you are willing to share that Mega link?

Yesterday I did have VCC attached hopefully I didn't do any damage.

Thanks again

Ya sure here is the Pre-Cuts: https://mega.co.nz/#!LElwWJRB!jJsXuIsni0K3eUJaFZAew6G1Wddgtj2lv5269HMRX8M

If the Router is still booting your blooming lucky mate. I'd never put anything to VCC just because it will sometimes fry the crap out of the Routers.

Have fun BTW do you need a Guide?

Thanks for the precuts! Sure, if the guide differs to what is on page one it would be more than welcome.

It boots (still stock firmware) I should probably buy a lottery ticket because I had no business even attempting to do the soldering + then I connected VCC  :lol:

Thanks hacktrix2006!

Code: [Select]
Firmware Version:0.6.0 1.10 v0021.0 Build 150409 Rel.40749n

Hardware Version:TD-W9980 v1 00000000

I gave up trying to backup my stock device. But I flashed to your precut image as per the instructions and then upgraded to the G.INP Beta firmware via the Web UI successfully.

I will go back to running in wireless AP mode for a little while before trying to retire my aging BT HomeHub.

Good stuff, I appreciate the sharing + it was good to see the output of the commands in your document.

Pretty promising device for the price!

Congrats mate glad it all went well. W9980 firmware is working well on my internet connection no issue other then the crappy aerials being 5db / 3.5db.

The aerial situation interests me.

The internal two 2.4Ghz antennas look fine but I will probably chop them off and add a set of RP-SMA connectors to open up other options.

The three external aerials for the 5Ghz radio appear to be needlessly large. I admit my understanding is limited but from what I can gather given the rating they should be much smaller in size than the 2.4Ghz antennas.

Some devices apparently share the same set of aerials to both 2.4Ghz and 5Ghz radios, but this is not the case with our device. When they get shared like that they seem to be called "dual band" aerials and are simply a cost saving compromise and are pretty much just 2.4Ghz aerials that work "ok" on 5Ghz, im wondering if we have been lumped with 3 of those because that's what TP-Link had laying around.

Either that or the aerial casing is 90% empty and just for show.

I haven't been able to open one of the aerials to confirm either theory and I would rather not destroy one by cutting it open. I am happy to be corrected, I am just trying to understand whats going on.

If you fancy chopping one of the aerials open let me know  :D Also if you are interested in DIYing a new set of 5Ghz aerials there are many examples on this YouTube channel.

It would be nice if we could increase the transmit power of the radio's also but from my quick testing (iwconfig ath0 txpower) they appear to be limited to weedy 17dBm or 50Mw.

anyway to increase the power on TX. Its the 5GHZ that sucks for me 2.4GHZ is fine infact  two walls between me and the router and it still is a full bar signal on 2.4GHZ but 5GHZ is less then 3 bars if i am lucky.

It's a simultaneous dual band device meaning it can use 2.4GHz and 5GHz as 2 separate networks at the same time. 

I agree that the 5Ghz is very poor, I had to be in the same room to see any benefit from the 5GHz range.  As soon as I moved to the next room it wasn't any better than 2.4Ghz. 

The 2.4Ghz was ok......
.. but still not as good as my VMG8324 which has (2x2 MIMO) 11n, so although my Zyxel doesnt have 5Ghz it does appear to have a better range reach meaning I can use my ipad at the very bottom of my garden, which unfortunately just drops out of range if I use the TP-link.

Im not sooo not impressed with all the 5 GHz hype.  :(

I've been using 5ghz for years and never had a problem with range. Originally I was using a HP Procurve A/B/G wireless access point, but recently I switched to an Asus RT-AC66U.

I also have an ASUS router (RT-AC56U) which supports 5ghz.
(I am running the latest custom Asuswrt-merlin (Ver:378.52_2) software)
It is much better than 2.4ghz in terms of throughput and range has never been a problem.

In fact the problem is that the range extends too far outside, in the wrong direction;D
(Cannot move the router from its location without routing long cables for power/ethernet etc.)

I'm not sure if anybody can help, but I'm stuck trying to crossflash my TP-Link TD-W8980. I'm moving over to Zen and an FTTC service (in 3 days). I already had the TD-W8980, and would rather use it over the Zen supplied Technicolor TG589vn v3. The part that isn't working, is loading the cut image into memory. I'm on Windows 7, but have tried it on WinXP as well.

I setup a Tftp (Tftp64  - Philippe Jounin). I can test this working via Cmd.exe and "tftp -i 192.168.1.73 get 123.bin".
When I try to copy the bin file over via putty, it just seems to time out.
Putty and the serial cable connection seem to be working fine.
I renamed the cutimage from TD-W9980_cutimage.bin to 123.bin to save time typing. ;D

The original poster's instructions assume prior knowledge, which is a little frustrating. It's all new to me. It's a pity the guy with the putty screenshots didn't post that info. Any ideas anybody?

Try disabling windows firewall.
In my initial tests with tftpd32 I'm stucked using win7 because the firewall blocked the service. Winxp works fine without changes.

Epoch I can PM you the link that hacktrix2006 shared with me which includes some screenshots. I'm unsure if he wants it to be public or not.

I used the same Tftpd64 as you.

At a quick glance, you set your IP + serverip OK just like I did. But the next command appears to differ "tftp 123.bin"  is what this guide suggests. Perhaps yet another way to do the same thing I am unsure.

Anyhow check your PM :)

Go for it, just be warned its a draft version. Its not perfect but will get job done. Also need some views of the drafting so it can be made perfect for public release.
