Link speed down after new router installation

Engineers came round to replace aging gigaclear router with new router and wall unit.
download speed was around 45 and downloading movies was around 4-5mbs.
Weirdly new broadband speed is up to around 80mbps while download speed downloading an movie
is 2mbs.
Unfortunately the engineers had no solution and no real explanation!

I am using several Tp- Link powerline adapters and house wiring is getting on - nothing beyond the
router has changed. The engineers changed signal from 27 down to 5 which apparantly is closer to
where it should be.
Any help would be greatly appreciated - The original issue was broadband kept dropping out, apparantly hence signal strength being reduced.
I would expect 8-10 mbs at 70-80 mbps
Thanks

Just had laptop next to gigaclear router. speed at 200mbps. no change at link speed. downloading movie around 2.5mbs.

Firstly, do testing on the router and not the powerline adaptors. Otherwise you don't know what's happening. Don't confuse issues. You mentioned laptop "next" to the router - was it connected to the router with an Ethernet cable? You also don't want to mix wi-fi issues here.

I'm a little bit unsure about the 45Mbps speeds as I didn't think Gigaclear did anything in that range?

What are you using to download and where are you downloading the movie from? Was this Gigaclear before and Gigaclear now?
It could be you now have IPv6 and somehow routing on that is slower due to a different route.

Laptop next to router, was connecting via WiFi.
The router is in cloakroom hence several Tp links round the house.
The router that was replaced one of gigaclear's first ones. When broadband first introduced.
Our plan was 50mbs and been like this since then. Initially speed was around 20mbs at tp links. I uprated tp links to later ones. I think they use mme that utilises 2 or more of the mains cables for better connectivity.
It worked better and got roughly 45mbs via wifi at those outputs.
For several years it occasionally dropped out. I've always presumed it was house wiring. Recently got worse.
Got engineers over, they replaced router with linksys router and wall unit.
Downloading using upto date pc, i5, 9th gen processor.
Websites like Netflix and amazon prime.
Gigaclear before and now!
Engineers says problem with house wiring and don't know about tp link adapters. They suggested getting lynksys pods for best results.
Thanks a lot
They also said these new speeds, 200mbs are more normal

will test later from router

my laptop only uses wifi.
in control panel, ipv6 Connectivity: no netwoek status

managed to reconnect ipv6.
no change in link/download speed. still around 2 - 2.5mbs

People are trying to help you but it's not going to be possible until you have connected a device with a cable directly to the Gigaclear router.

understood!
will sort as soon as possible

Now connected to Lynksys router with ethernet cable.
download speed up to 220mbps. link speed at 3mbs.
ipv6 connected
Thanks

closer to 5mbs with wired connection

In reply to a post by HAPPY56:

download speed up to 220mbps. link speed at 3mbs.

Could you explain what you mean here

Am totally confused by the OP's explanation of the issue (probably bad terminology), would be good to understand what speed they are paying for and what speed they are getting when doing a speed test through a wired connection, all this about downloading movies is not a good measure of speed.

when I was speaking to the gigaclear engineers was explaining that the download speed into
the pc when downloading movies, netflix amazon prime was around 2.5 mbs. In there answers
they were saying the download speed is nearer 200mbps. I wanted to know why the old gigaclear router had download speed of around 45mbps and link speed or download speed downloading movings into the pc was around 5mbs.
They had no answer to why the new router and wall unit was up to around 200mbps and the download or link speed into the pc downloading movies was down to around 2,5mbs.
I was hoping that link speed was the correct terminology to describe connection between the router and pc - not speed coming into the router!
my last post says 5mbs where the laptop is connected directly with ethernet cable to the router.
The router is in a cloakroom hence powerline adapters around house.
my second to last post says 3mbs but that was an mistake - it's arounf 5mbs directly plugged into
Lynksys Router
Thanks

Have you confirmed the 200Mbs downstream speed with a speed test on your equipment or are you relying on what the engineer said?

The conversion between Mbps (megabits per second) and MBs (megabytes per second) is as follows

(8 bits = 1 Byte)

Mbps divided by 8 = MBs

MBs multiplied by 8 = Mbps

A download rate of 2.5MBs is equal to only 20Mbps

Tested new download speed on browser, gigaclears speed test around 200/220Gbps which is good!
Yes, the conversion is 8 bits = 1 Byte - this is my question and problem!
I would expect the speed of download closer to 8mbs coming into the pc Its Not - its around 2.5mbs.
the old router broadband speed around 45mbps and 5mbs coming into the pc.
new router is 200mbps and 2.5mbs coming into the pc.
i've only downloaded movies and tv series and went to google chromes download page to view the numbers. always been reasonably accurate.
original payment plan was for 50mbps and all these years been fine. I was happy with 5mbs.
I only upgraded as it was dropping out so got engineers in and they replaced with new.
They said the signal was too high which probably causing drop outs. it has now been reduced and new router installed - so basically not an good result!

Are you using a Windows, Mac or Linux? What program are you using; or web browser, and do you have any security software installed?

If using Windows (10 or 11) if you bring up Task Manager, you can see the actual speed in the same units that broadband companies use. For example "megabit per second" often written as Mbps. This is very different to "Megabytes per second" that you will see in a download, often written MBps.

To illustrate I just downloaded a Windows 11 disk image (ISO) from Microsoft, from this page:
https://www.microsoft.com/en-us/software-download/wi...

My web browser said the download was running at 46.0MB/sec, see picture:
https://i.postimg.cc/P51KxZM1/browser.png

Task manager shows receving at 401 Mbps, see picture:
https://i.postimg.cc/ZKW41Yxx/tm.png

This is fast as my broadband is only advertised at being able to do 380 Mbps.

So for absolute clarity are you saying when you connect via a wired connection to your router and use a web browser and do a speed test the results show your getting 200Mbps download? yes or no

Correct!
Wired connection to router via browser is 200Mbps using gigaclear speed test page.

Then everything on Gigaclear's side is working as it should

using windows 11 pro. chrome web browser. microsoft security.
I'll look into windows 11 disk image soon.
Will get back soon - just looking at task manager

Edit: Sorry this should have been directed at the OP

Just a thought, maybe Gigaclear are routing the movie downloads via a convoluted route causing them to be particularly slow, it won't be the first time an altnet has routed internet traffic via multiple foreign countries.

you would have thought so but still the speed of download into pc is half what it was - the router they replaced was also gigaclear.

When the router was changed the IP address would probably have changed as well and this may have affected the routing of your internet traffic.

i tried accessing router settings but have to sign up to Lynksys app - not done yet!
seb, first reply to me suggested IPv6 maybe slowing it down an bit.
was going to check that out

this iso file would find my windows edition to accurately test download
- will try soon

Try a non-Gigaclear speed tester like Fast.com so not to limit the test to just the Gigaclear core network, don't forget to connect to the router with an ethernet cable.

Note: If you click the more info on the suggested test site it will tell you where it thinks you are and what test servers you're connecting to.

Fast.com shows internet speed 230mbps with 4.8mbs download.
wired directly to router

sent an email to gigaclear - see what they say

I'm sure your winding us up now as what you're saying doesn't make any sense. I'll leave this to someone more patient than me.

Are you...talking about your ping time in ms?

In agreement with the post directly above mine, the effort you're putting into this is a fraction of the effort people are putting in to try and assist. If you're not bothered about accurately reading and relaying the things you're seeing on screen then that's obviously your right but you will put people off. Nowhere does Fast.com report an "internet speed" and a "download speed", so you've seen some numbers and have decided what they represent. You need to either start accurately reporting what is being shown to you, or upload a screenshot using a site such as https://postimages.org/.

Weird!
ITs gone from 2-3mbs to 5mbs having plugged directly into router - Where's the improvement in that!
At 200mbps you'd expect 25mbs download
Wheres the wind up!
If its through TP link and wifi its around 80mbps internet speed and download of 2-3mbs

@Happy56,

It is sounding like you could do with someone that is used to translating technical stuff such as networking into a non-technical language that you should be able to understand. Are you based in the south of England somewhere? I would be willing to offer my skills to help you sort out this issue. If you're interested then drop me a DM or email me ([email protected]) and I will do my best to sort your issue out.

Yours,

what gigaclear package are you on

Also can we have a screen shot from

https://www.thinkbroadband.com/speedtest

You are mixing up Megabytes with Megabits.

ITs gone from 2-3mbs to 5mbs having plugged directly into router

What is "IT"? What exactly are you doing that was 2-3 and is now 5? You suggest this is a download but a download from where of what and using which software?

It is very confusing that you are saying the speedtest is over 200 but the download is 5 - the 200 is the download speed so we need to know what you are doing when you only get 5.

IT being 2-3mbs via tp link power line network via wifi. router is in cloakroom hence powerline adapters.
plugging into router directly with ethernet cable is 5mbs.
download from netflix and amazon.
no specific software just downloading from these sites.
it is confusing as one would expect closer to 25mbs with 200mbps!
not doing anything unusual. going to netflix/amazon to download and opening another google chrome tab and then downloads to view download speed.
been fine for years until new router was installed.
the old router was downloading at 5mbs via powerline network adapters and wifi

It may be a dodgy cat5e cable syncing down to 100mbits/s...... but untill we see some pictues i don't think we can resolve anything for the OP

p.s "it" was intentional 😂

do the tests without the powerline adaptors .

also screen grab the results ..and use this service to provide us with the picture.

Please use

MBytes/s for Megabytes per second
Mbits/s for megabits per second.

a 200 Mbits/s service should give around 20 to 25ish MBytes/s download

idealy just screen grab and we can deduce properly
