It could be wireless interference or congestion on your end, or particular settings on your router. If you still can’t get it working well, change to a better router. I would recommend the Tp-Link C7 v4, but not sure if you are willing to try TP-Link again, so I would recommend Asus as an alternative brand, as recommended by bro Jjuggler.

Again, it could be wireless interference or congestion on your end, or particular settings on your router. Last resort, change your router. I don’t know why AC1200 has so many problems, when their other routers are really good. You could try the Tp-Link C7 v4, or Asus routers as an alternative brand.

That might be it, but there have been multiple complaints about the TP Link AC1200 for some reason.

Homeplug is a good solution, if you are on the same wiring phase, but if not, it could be very inconsistent. I am quite surprised that the C7 v4 is not performing as expected. My C7 v2 that I used to have is very good, and its signal is quite strong as well.

True bro. I can’t really recommend the lower end Tp Link models now, as there have been many inconsistency issues. The least I could recommend for budget issues is the Archer C7 v4, and even then, I am hestitant to do so as I am worried about the performance. Asus is good in the sense that they keep updating their firmware, even for their older models, something Tp-Link should also do for their older models, as they seem to be more keen to releasing new versions of their routers than improve on an older model’s firmware.

Don’t get me wrong, I like Tp-Link products, and am a fan of them, but they need to step up and address some issues that people have with their routers.

There is new firmware for AC1750 V4 but i'm not keen to update as im worry it will be screw-up. And im checking TPlink Malaysia website it seem like V5 is on the way. In fact before i bought this router my friend has already recommend switch to homeplug, i'm quite regret did not listen to his advise. Btw the homeplug i'm going to buy is Tenda PH3, i will be buying from Taobao on 12.12, after did some research it is the cheaper gigabit homeplug with the price less than RM200. I never heard of this brand to be honest, but since the price is so cheap might just give it a try.

As I say before, homeplug is very inconsistent and it is not 100% reliable. If there is electrical noise, it will be affected. But, if it is as cheap as you say, it would be worth a try.

If you are not confident in updating the firmware, then don’t do it. It will be very hard to roll the firmware back if there are any problems.

Yup, that is what i think off since i don't have much knowledge to configure router

TPLink suit for those who wish to get an high performance with affordable rates and tplink wins in terms of budget. There are some good routers from tplink. However, if I want to vote for a worst router from tplink, I would without any hesitation will tell c1200. I don't tell tplink dont give good products, only few affected models without proper firmware damages the reputation of tplink.

Where to check uptime on c1200?tm just change to this router for speed upgrade ..but i cant check when the uptime for unifi connection..

Don't have such thing in this router.

Hmm..too cikailah this router.haha.seems this router not stable. As i saw the ip keep changing .cannot monitor the uptime connection.how to solve this issue.before this i use dlink drl..but now after renew contract they change to tplink

Why do you want to monitor the uptime anyway? You mean the router is constantly rebooting by itself? Just be aware that if you are not paying for static IP, your IP will keep changing as you are under dynamic IP.

seems like DIR850L is way more better than C1200.

C1200 WiFi 5GHz not able to achieve more than 85Mbps but 850L does.
Also, it does not load up some certain website or app , but mobile data works perfectly and on previous 850L works too.

It might be so, but remember to check that the firmware for your DIR-850L is 2.09. If you are using a firmware version before that, you are open to security vulnerabilities.

but what really annoys me right now is the app problem. It just does not load. What causes that ? I am talking about the OnePlus Community app, it does load on mobile data and on 850L but just won't load with C1200.

Plus, like I said previously, there is also a delay on Play Store downloading or updating.

Your guess is as good as mine. I don’t know what could cause that. I have used the DIR850L, Archer C7 V2, and am currently using the AC3150 V2, and never had any problems on Play Store downloading or updating, or even App Store for that matter.

I know la dynamic keep changing.means this router not stable lor..always restarting/reconnect..with dir 850L.. 30day without single reboot..nvm.ill log report to tm.i ask them to change other router..

Bro, you totally misunderstood my question. How often does the IP change? It could have nothing to do with the router, and more to do with your router’s lease time on TM’s side. If it changes few times a day, then yes, it could be the router’s fault. If it changes a few times a week, then it could be nothing wrong. It doesn’t mean a particular router is stable if the IP doesn’t change for 30 days, and vice versa. Did you check the system log on the AC1200?

TP link AC1200 is piece of shit ... end up i use back my old Asus RT-N12 .... still best router for my condo.... long loading time for TP link AC1200.....

c1200 = upgrade to EU firmware 1.1.1 Build 20170706 rel.65715 (EU). Enable 5ghz beamforming at System Tools, System Parameters. That build fixes packet fragmentation/MTU issue which is the reason why some website can't load. As for 5Ghz, double check channel 80Mhz bandwidth and channel congestion. Yes, channel congestion can happen even at 5Ghz.

About that reboot issue....disable SPI firewall and problem solved. But you are left without firewall.....

Today 3 times the wifi suddenly missing. As i remember the ip changed 2 times.is it normal.any other way to solve this issue..i just use this router 2 days only..

Unfortunately, as I say earlier, I don’t know why the AC1200 is really bad. All I can say is that their lower end models seem to be suffering from firmware related issues.

Sad to hear that you have to employ drastic measure to do so. It could be a firmware related issue with the AC1200.

Bro, my bad. It seems to be the router’s fault then. Bad firmware would be my guess.

Possible reset to factory may resolve the issue?or flash to latest firmware..now running on v1 eu 20170905
