I don't recommend to use the 2.09TM. That is because this firmware has caused terrible internet connection especially wifi. My home LAN style, i prefer to use DHCP with pre-assigned IP. I don't set the IPs at the devices but only at the router. This firmware cannot do that that affect the internet connection. Finally I revert back to 2.08TM. I can set 14 IPs manually at the router in the 2.08TM. Not the 2.09TM. I also faced some problem related to IPv6 in the 2.09TM. My network printer that can support IPv6 cannot receive IP from the router.

If anyone here want to revert back to 2.08TM, switch off the router, hold the reset button several seconds until the one of the LEDs is blinking. Then you can access the router's page (emergency/recovery), http://192.168.0.1 and flash the firmware.

Looks like D-Link Malaysia's problem. They didn't test the firmware properly. I also tried to use the 2.20v, from D-Link international. It is beta, can connect to internet but weirdly cannot set manual dynamic DNS. Arghh, looks like D-Link worldwide, not only Malaysia is problematic to me.

Generally, this router s***ssssss big time. I'm used to TP-LINK router.

In TP-LINK
1. If i want to change my DNS server, the router will simply disconnect and reconnect.
2. Reboot/configuration update countdown are accurate. After the countdown, simply F5 and you will see your web interface.
3. No problem with having many (I'm talking about less than 20) fixed IP in DHCP.
4. Generally, snappy interface.

In D-LINK
1. If i want to change DNS server, the router will reboot. This takes longer time.
2. Reboot/configuration update countdown are not accurate. You have to F5 several time after the countdown at the no internet connection page.
3. Several problems in several model of routers. I'm lucky to find that 2.08TM of the DIR-850L doesn't have this problem.
4. Slower than TP-LINK but not too slow. Looks buggy.

If only TP-LINK produce their own Network Attached Storage (NAS) I will make sure there is no D-LINK product in my house. Considering to replace my DIR-850L soon but still use my DNS-320L NAS by D-Link.

Yes, u r right. TP-Link is definitely better than D-link. I'm considering one of their MU-MIMO routers (Archer C9 is not MU-MIMO)

Synology is one of the best NAS manufacturers. I'm considering to try their 10Gbps NAS to cater our home LAN requirements (a lot of 4K streaming, local backup, bluray encoding etc. through the LAN). Thank God we dont need Plex server running. Otherwise, i7-grade NAS (desktop) is a must to encode/re-encode the 4K videos on-the-fly.

Sorry for dragging the discussion away from the originally intended by the OP.

For the case of MU-MIMO, Samsung Galaxy S7 and S7 Edge are the perfect example for the degradation issues. They are 2016 flagship phones. Newer phones with MU-MIMO are just fine. One of the example is in the article posted, Google Pixel. So, in this case, I (not only me, but a lot of others) blame Samsung (or the chipset maker) for not really following the standard in MU-MIMO. Thats why Samsung do not advertise S7 as MU-MIMO capable device. Only S8.

For the Archer C9, of course dude! There is no router (at least for home user) currently have 10 Gbps ethernet ports. But this doesn't mean that home user cannot have 10 Gbps LAN connection. You can simply connect the router (any router) to 10 Gbps switch and connect your 10 Gbps peripherals (desktop, laptop, NAS that support 10 Gbps) at the same switch. By this way, you cannot have bandwidth of 10 Gbps to the internet (of course, the fastest broadband in the world today for home user is around 1 Gbps) BUT you can have 10 Gbps of bandwidth for your local network. I need this since I can easily utilised 500 - 600 Mbps in my home network for local content e.g. local streaming, local backup, CCTV recording for one PC. For a total of 6 heavy users in my home, my 1 Gbps LAN is very congested. The price for 10 Gbps switch as well as ethernet PCI card are become lower these days but the price for 10 Gbps NAS is still expensive. Yes, there are 10 Gbps NAS if you are still wondering:

A little update. Just changed my router from Dlink DIR-850L (AC1200) to Tplink Archer C2 (AC750). I know the Tplink is an older model (and slower total throughput in Wi-fi) but now I can connect to TM IPv6 and maintain stable IPv6 connection even with Google IPv6 DNS. I couldnt do this with the Dlink. Signal strength from the Tplink is better due to its external antenna (Dlink only internal). Very happy with the Tplink.
Now i'm in dilemma in choosing Tplink vs Dlink switches for my new home. 16 ports Cat6 in total. 24 ports Tplink switch is cheaper a bit compared to 24 ports Dlink. Review-wise, many people use Dlink. Any idea? Both fanless. Pls dont suggest Cisco as they are very expensive. Only unmanaged switch needed.
Correction on my previous posts, 10Gbe switch are still very expensive and I'm postponing the idea of having 10Gbe connection for future.

From my previous experience with this model, yes, it works (even with the previous firmware) BUT only for IPv4. The DIR-850L have problems connecting to TM's IPv6 and couldnt set the DNS (to Google IPv6 DNS for example).
Hope this help.

Yes, I realized that before purchased the C2. I don't have plan to use the wifi (I already disable the wifi, plus, I'm quite happy with all the features and speed of its web interface). The router is connected to a 24 switch and other access points will take care the wifi. Why I'm doing this? Because my modem and router is located inside a room where the main communications line (phone and tm fibre) comes in and 16 CAT6 will cater the whole house LAN, wifi and even phone line. I don't want to have the modem, router beside my TV. BTW, thanks.

Thanks too about the advice on the switch. I bought TP-LINK, the desktop/rack version, as it is the only model available here in my place. It comes with bracket for me to mount to my 19" network rack.

So sorry OP, I kind of distracted the purpose of this thread. Let us continue to discuss about the DIR-850L? Anyone managed to get IPv6 with the latest firmware? I couldn't. With the TP-LINK, I can (refer to the attached image)
