Hi, I am using TP-Link Archer C1200 router TM unit at home for browsing, some gaming, internet banking usage.

I want to ask, at router management setting, NAT Forwarding, ALG, UPnP, can i disable all those. it seem not needed for me but i am not sure.

Can i safely disabling all those within NAT Forwarding, will it make my router less secure?
does it reduce the CPU load on the router?
please help

Hmm? Are you using TM beta firmware at first post? Downgrade successful with TFTP?

Yes, disable all ALG and UPNP. It will make your router MORE SECURE.
There are some malware/virus/trojan made use of UPNP for portforwarding and exposing victim system to the Internet.

No, I upgrade directly to "Archer C1200(EU)_V1_180124" then try to go back to TM firmware but received "unable to upgrade" message.

I have not try TFTP to go back to Tm firmware yet because the procedure is complicated to me and this global version work well.

just seen some post saying disabling WPS, ALG and UPNP can reduce CPU load and make network more secure but i am not sure will it make my network difficult to use or slow it down or something else. that is why i ask

I just upgraded to V1_20180208 and it seems they added the @unifi suffix again..

Same here. Hence I totally ditched the router and continue using my RT14UHP again. Guess, I would have to save and fork out some cash for an AC Asus Router then.

Re-flashed firmware from EU support page. Will monitor conditions. Current page..

Some people prefer TP-Link TM Malaysia Firmware due to having more 5ghz channels....

RoxyGal, the official TM Malaysia firmware is out.

True although the only annoying one is unifi shameless plugs

I know but after update to international firmware I can no longer update the UNIFI latest firmware. It stated unable update firmware. Any solution? @JohnLai , can you try for me? I think you too unable to update to UNIFI latest firmware

Biloxee already pointed it out.

TFTP method ought to work.
Difference is the IP would be 192.168.0.66

@JohnLai

Tried TFTP method, able to access to c1200 restore firmware and upload the stock unifi firmware but when reboot it will only revert back to the last firmware. So TFTP method doesnt work

@hollowsxd

Can i know the latest unifi firmware dated V1_20180208 for the wifi 5ghz whether they have upper channel 144, 161 and above?

Guess you have to contact TP-Link for more info.

As for your 5ghz channel question on the TM latest official firmware, it contains 36, 40, 44, 48, 100, 120, 161 and 165.


EDIT: Are you sure TFTP successfully upload TM firmware into the router?

Did exactly like the video above after refering few tutorial including the above. Succeed in recovery but when it boot, same firmware as before. Dont know what went wrong

What did you rename the latest TP-Link-UniFi firmware to?

first attempt using tftp failed in the log viewer because using the wrong filename. In the log viewer it will state the correct file name so i renamed it to the correct one as stated. Cant remember it, something like C1200_v1_tp_recovery.bin. After renamed it to the right filename, it even showed correct file block transfer

Oh ok, perhaps there may be a need to strip the boot section of the latest TP-Link-UniFi firmware since the filename contains the word "boot" per this wiki. Other sources.




1) Download dd for windows from http://www.chrysocome.net/dd
=> dd-0.6beta3.zip

2) Extract dd.exe to a folder

3) Rename the latest TP-Link-UniFi firmware (C1200v1_eu_tm-up-boot-1.0.0 Build 20180208 rel.57928_2018-02-09_10.03.18.bin) to orig.bin and copy it to the same folder where dd.exe is located

4) Launch the Command Prompt window and navigate to the directory where dd.exe and orig.bin are located and type the following command
and hit [ENTER]

==>

5) Rename tplink.bin to C1200_v1_tp_recovery.bin and perform the TFTP recovery process...


Worth trying?

Tested. Stripped uboot and restore again. Still back to the same firmware. What went wrong?

been using global firmware "Archer C1200(EU)_V1_180124" to replace TM stock firmware since 10Feb.

already 9 days, the router seems stable, no reboot by itself. wifi range is good, can cover my 2 story teres house all corner using 2.4G band. speed can achieve 33mbps down 11mbps up.

cpu load =11% memory usage 41%

....RoxyGal

A question for you. You said tftp flashed TM firmware automatically reset to EU version after reboot.....

Try these.
1) TFTP older version of the firmware C1200v1_eu_tm-up-boot-1.0.0 Build 20170905 rel.41738_2017-09-05_13.51.02, but DON'T REBOOT once you are able to access TM firmware configuration page.

2) Right away flash the current C1200v1_eu_tm-up-boot-1.0.0 Build 20180208 rel.57928_2018-02-09_10.03.18 via the 41738 upgrade pages.
