Samsung Smart TV slowed its streaming speed

Jul 21, 2016 1:21AM PDT

I have a Samsung smart TV (UE32ES6300) and until recently the streaming worked fine (Iplayer) and I could watch programmes however over the last few weeks the TV has really slowed down. I have checked my broadband speed with a laptop, tablet and phone on wireless whilst stood next to the television and these all read about 3mb/s (okay for SD TV). When I use the Internet browser on the TV to check the broadband speed it says that the speed is only 0.8mb/s. Anybody know why the TV is getting a slower broadband than all the other items. I have checked that all other items are off when I check the speeds and done all the basic checks, I think I need to change something on the TV (settings/software) to get it back up to speed but I don’t know what. Incidentally I also have a NOWTV box that works fine. Any Ideas why the TV has slowed down during streaming?

Samsung Smart TV - wireless network connect speed is poor!
Nov 26, 2017 10:04AM PST

Very good info, but I'm a novice with these electronics and need more help!
My Samsung Smart TV (4K 8500 series) needs to work wirelessly as it is too far from the modem (WideOpenWest (WOW) and wireless router (Nighthawk AC 1900, Model 7000 seems to work fine now that I updated the Nighthawk software from their site). All are 1 year old or less. The WOW modem is a replacement and just a few weeks into service. Old modem had speeds only around 15 mbps download and WOW advised a new modem (free replacement).
Current status: When near the TV which is in the basement, the laptop and iPhone almost always show ~ 30 mbps download, ~5 upload. I've used the to check those and also used that test on the TV even though the data might not be accurate (per some folks since it is not a PC). The TV test only provides a download speed which makes sense to me.
My 'wired' desktop in the home office shows about 33 to 35 mps download.
All but the TV are 'usually' at the 30 mbps download noted above. The TV is often at 1 or 2 mbps but sometimes at 25+ mbps.
I watch workout videos and they usually just freeze and then spin and spin, and then maybe catch up in time so I give up and end up watching on the laptop.
Last bit of info: I check the connection at Netflix and with two speed checks got values of 11 mbps and 0.026!
1. What is the Samsung number you called?
2. What is the DNS setting you used. Because of connection issues I changed mine right after getting the TV to as noted in a support blog and in the TV booklet.
3. If I need to do a TV reset, what is the critical info to write down before resetting (or I might never get it back to normal)?
4. Does the fact that the cellphone and laptop are sometimes slow indicate another issue?

Sorry for the length of this, but the buffering (if that is what the spinning circle means) is very frustrating. Try doing a workout video with 3 minutes of freeze frame every few minutes of workout time.
thanks for any help on this.

cant help much
Nov 28, 2017 10:13AM PST

I just contacted Samsung via their website but the e-mail address was
The DNS that they recommended is the that you have done.
I didn't write down anything prior to reset, probably not the wisest move but when you are frustrated.
good luck
PS - Occasionally my TV still slows down but I just turn it off and back on and try again.

Tweaking the Speed of Samsung TV is possible
Jul 22, 2016 12:39AM PDT

I also contacted Samsung to see if they would help and they sent me some useful tips, They suggested resetting the TV, ensuring the software was up to date and also one that really seemed to speed it up was changing the DNS server address. I don't know what the DNS address does but after changing it my TV's speed (still on WIFI) increased back up to around 3 mb/s and Iplayer now runs okay again.

Back to Samsung I fear.
Jul 21, 2016 7:00AM PDT

Why it could be WiFi or other, a recent change by Samsung means it might not be your gear.

Call them and they should walk you through the usual steps of firmware checks, resets, and a DNS change.

good advice

Thanks - you were spot on - samsung did help - see my post.

Skip the wifi altogether- use the ethernet port in back
Jul 21, 2016 9:19AM PDT

Your HDTV has an Ethernet jack in back. If you want to avoid the hassle of intermittent slow wifi speeds, just use a traditional wired connection. Works like a charm IME to fix streaming issues (Netflix, etc.). There's nothing inside the TV settings that allows you to tweak speeds, etc. You have no control over that, and more importantly, what's upstream from your residence and/or ISP.

bandwidth a 10th of what it should be
Mar 29, 2017 8:39AM PDT

Just wanted to add my experience. I am really into bandwidth speed and fairly technical. I check my speed a lot and hard wired to my comcast router should be 240 meg download. Ran speedtest on my new 2016 9000 level samsung smart tv and first got like 6 meg download. Strange but the upload was the normal ~11 meg upload speed. How many tv's need to upload? So I moved the ethernet cable directly to my comcast router from my Nighthawk and then started getting ~25 meg download. Better but still no where near what my download speed should be. So maybe Samsung is throttling for some reason. TV is new so haven't had a chance to look at the settings. It would be funny if the wireless was faster than the hard wired but I haven't tried that yet.

Yes, the TV is not a PC.
Mar 29, 2017 8:43AM PDT

It's no good for testing bandwidth since it's no PC. Consider this. You only need so much speed even for 4K UHD playback. Read

Why should a TV do more than what it needs?

Wireless faster then wired
Nov 12, 2018 1:39AM PST

My Samsung 4K tv's wireless speed is 3 times as fast as the wired speed. My provider said they connect to different modems and obviously, the wireless one is better. How can that be? It makes no sense how wifi is faster then wired

- Collapse -
Here's how.
Nov 12, 2018 8:56AM PST

Many TVs have 10/100 Ethernet and if the WiFi is 5GHz that can go over 100 megabit. Since Netflix for example calls for 25 megabit for UHD 4K, there's no reason to make TVs with 1000 megabit ports.

Makes no sense
Nov 12, 2018 9:27AM PST

If that’s true, why does the manual say to hookup the Ethernet connection because it’s faster? Also, my streaming constantly blurs with what I’m expecting is the speed can’t keep up. I’m disappointed that I did not know Netflix calls the shots on what tv manufacturers put in their TVs. There is no reason why with the costs being so low why they can’t put at least something like ps4 has in their system. My ps4 gets 350 on the same internet. Very disappointed

The manual is generalizing.
Nov 12, 2018 9:55AM PST

And until just a few years ago, you rarely found homes with 802.11ac where you got over 54 megabit. These manuals are rarely updated to dive into a full treatment of networking.

The PS4 has all the latest networking.

Since the TV for just about everything only needs 25 megabit, why should it do more?

Not with Dazn app
Nov 12, 2018 11:20AM PST

Clearly for me watching my football on Sundays it’s not. Lol
I just don’t get why they just didn’t put in what ps4 has, probably didn’t cost more to do so. I get what your saying that if Netflix says u don’t need more, why put more. Well, it’s like u said technology is changing and I just feel they should have put in a more powerful modem in a 2018 tv. My app which is legal is the only way I can watch football in Canada. Pretty stupid if it’s constantly buffering. Oh well, thx for your input. Take care

This is why
Nov 12, 2018 11:33AM PST

I connect with the best connection. If you want to slam Samsung for having only 100 megabit ports then you have to consider returning that set.

I could not find the Dazn app in the Samsung store. I wonder if me being in the USA is why. Anyhow why not use the faster WiFi?

Also, if you feel Samsuing needs to update the manuals (they do) be sure to let them know.

Only in Canada
Nov 12, 2018 12:00PM PST

Apparently, us Canadians are forced to view nfl Sunday ticket on Dazn app. You can find it in the google store. I’ll just use my android box and watch football illegally so my video won’t be blurred every 5mins. That way my android box will at least give me full speed when I hook up my Ethernet cable.

That explains a lot.
Nov 12, 2018 12:19PM PST

Samsung and others are not making Smart TVs to compete with the PS4, PCs or those Android boxes. They are focused on the Netflix and such since they get a cut of those services.

So in recap, they are not attempting to explain how things work today and are not interested in much beyond the apps they have in their stores which they get a cut on.

Seems odd that Netflix gets by with a paltry 25 megabit and Dazn needs far more.

Smart tv webrowsers
Dec 4, 2018 1:56PM PST

all smart tvs have poor web browsers samsung Tizen is one of the worst -my solution was to buy a microcomputer odroid c2 this allows web browsing unlike streaming devices such as roku -very fast -has a quadra core cpu-also small -3x2 inches-costs $100

Slow speed on Samsung TV wifi
Dec 26, 2018 3:04PM PST

Century link just updated my internet speed fron 20 mbps to 40 mbps. After numerous speed tests on my WIFI, laptop 36 mbps, cell phone 40mbps, Samsung 2015 55" smart tv 7.3 mbps. I called Samsung and had to do a manual firmware update. Time consuming and the results were not any better. Hooked up a ethernet cable and it boost to 16.3. Wondering why I wouldn't get closer to 40 mbps? Went to an older Samsung t v further away from the router and was getting 16.7 mbps through wifi? I figured it out. My Roku on the older TV is a better WIFI receiver than the built in Wifi on the 55. Solution I moved the Roku stick to my slow 55" Samsung TV now have 20 MBPS. If your Samsung is slow get a Roku stick.

WiFi solution.
Apr 22, 2019 10:24AM PDT

I’ve been struggling with this issue since I move to a an apartment. Very slow WiFi on my smart tv and obviously very annoying.
I’ve updated software,contacted amusing CS with not much help. So I decided to do some research and I found out that if you live in a place with a lot of WiFi routers the channels get very crowded.
The solution is simple. Find the loneliest free channel, if you have a smart modem got to the settings ( 192.101. so forth) and scan for channel clutter. Look which channels r being used and select the one that is not.
