hi any idea why this giga lan port cant reach 800Mbps? is there something i did wrong?

Check your cable. Change to another cable, and see if that helps with the speed. Click the link on my signature and read all the green text.

my cable is a cat6 , the old ac1200 by tm can stil get 780Mbps dl,
unless this new router really cannt support 800 on LAn?

can reach 800Mbps.

1. firmware updated ?

2. try port 2-4.

3. reset the router and don't configure anything extra (just the WAN only), try again.

maybe limitation of my processor?

Yes, could be also, i3 and above no problem getting 800Mbps, only for those low end dual core pentium or celeron, or using 5400rpm harddisk , then will get a lot less, most likely in the 300Mbps region.

tried re-flash, reset, same result. getting 300 ish,

my processor is a old I5-2500k ,
oddly the old router can get 800l...

can I know your firmware version?

1.22SDH or something

its 1.22SHC..did you try contact dlink?
or maybe you can try flash custom firmware like dd-wrt or tomato.. Proceed with caution!!

they said after flash should be fine, but not

I think I'll return it and go for ac66U since the price is cheap now, can it fully support 800Mbps on Lan ,i wonder?

That is really odd, if you have not returned it, you can try downgrade it to a lower version firmware (like the v1.10 year 2015) and see (do reset first before downgrading). As 868L need to go for a lower version one before upgrade it to 1.22.

Asus router no issue, faster response than 868L (in my opinion), interface better also and more apps. Just need to get the hardware version B1 though. Only thing asus router is usually quite hot, so, its better to let it stand vertical for better air circulation.

Why with version B1 on the Asus ?

For B1, the cpu speed is upgraded from old 600Mhz (A1) to 1Ghz. Higher cpu speed means can handle faster for more clients. You can always check the spec for any router in wikidevi.com

Ohh yeah it's a B1

there is a update on the firmware, should i leave it or update? on the ac66u B1
