qwerty123:

 

Right. Wonder if your router does TCP MSS clamping, but sets very small MSS and causes excessive fragmentation of TCP packets. You can try either capturing traffic with tcpdump/wireshark or run iperf3 test to some public iperf3 server via udp and see if UDP speeds are higher, like

 

iperf3 -u -b 10M -p 5201 -c ping.online.net
Connecting to host ping.online.net, port 5201
[ 6] local x.x.x.x port 54308 connected to 62.210.18.40 port 5201

This is the output I got:

If you want to capture the actual traffic on the WAN port of the FritzBox, you can get it to do that via a page accessible from a link on its support page.  The URL for the support page of a FritzBox is <address of FritzBox>/support.lua.  Once you have the captured traffic you can use Wireshark to examine it and see if there is fragmentation or retries or anything else funny happening.

 

 

Thanks. I never knew this "section" even existed. However I'm not sure what to do here. Any specific instructions?

I don't see it mentioned above, please confirm speed tests are done over LAN and not Wi-Fi?

LAN. I can't stand WiFi - I use it for mobile phones only.

does a speed test over wifi from your phone or other wifi device show the same slow upload speed?

Just installed the Okla Speed Test app on my phone and the results are very similar - well the download speeds are considerably less, but everything else (Ping and Upload) are basically the same.

The fritz has a built in speed limiting feature, Please check that isn't capping you down low..

 

BuckoNZ:

 

I believe I found the area you mention. However it's grey out. This section - were the download and upload speeds are defined - is when there is another modem in the mix (ie. another modem is providing the external connection and NOT the FritzBox).

I have the 7490 model.

 

 

Noting the following, looks like you may have already tried this. however the ui your getting isn't what you should - 2D may have customized the fritzOS to nolonger allow access to change this.

 

I would try a factory reset, then test your getting a solid gbit link between ONT and PC (no switches etc inbetween just to count out any oddities)

 

 

 

Rerun tests, then switch cables and try again.

 

 

 

I personally would be going back to 2d on this and saying the upload speed is not preforming were it should be, causing both poor internet and issues with the phone.

 

2D will have access to chorus's tools where they can see your utilization (this would allow them to clearly count out any sort of upstream congestion from your end)

 

2D are also full capable of running iperf tests from the Fritzbox itself. this would allow them to get a speedtest at the port itself.

iperf Done.

 

 

So UDP upload looks better than speedtest's HTTP upload. Can you run iperf test for TCP as well? Wonder whether it's TCP or HTTP specific issue: 
iperf3 -p 5201 -c ping.online.net

 

What version of Fritz!OS your router runs?

Yes, it is on a blind URL so that you can only get there if you know the URL.

 

From the support page, click on "Packet traces".  On the Packet Trace page, there are buttons to start various different packet captures.  It is quite a while since I last used these, and as I am at the beach and accessing my network via OpenVPN, I can not run any captures to refresh my memoy of what each one does, so you may have to experiment a little.  My best recollection is that the "Internet" section top two buttons are for capturing from the DSL interface, so they are not what you want to use for a fibre connection.  I do not think I have ever used the "Routing interface" option, so I am not entirely sure what it does.  The eth0 interface is the one used for your fibre WAN connection, so that should be the one you want to capture from.  The lan interface is the connection from the FritzBox CPU to the hardware ethernet switch that runs the FritzBox's other ethernet ports - use that to see the traffic from your ethernet network to the FritzBox.  The two WiFi interfaces are for the two WiFi radios.  I think wifi0 is for the 2.4 GHz radio and wifi1 the 5 GHz radio.

 

When you click on a Start button, a little later a popup will happen asking you where to store the capture.  The options depend on the browser you are running.  I think the popup may not happen until the first packet is seen on the interface, so it can take a while if your network is quiet.  Once the capture is happening, run whatever test connections you want to see the results of, then click on the Stop button.  Then use Wireshark to read and display the capture file.

 

WARNING: If your phone is using VOIP, and a call takes place while you are capturing, you may capture the phone conversation (and Wireshark has simple options to allow it to be played back).  This is seriously illegal unless both parties to the call have been informed it was happening, so if it happens accidentally, delete that capture immediately.

Not related in any way to the actual issue but merely to correct this for anybody else who reads this - this is not 100% correct. The only requirement for call recording in NZ is that one party is aware of the call being recorded.

No, that reference is to recording something when you are personally present.  When recording a phone conversation, it is not the Privacy Act that applies, but a much older law covering phone conversations.  Both parties need to know if it is to be legally recorded without a search warrant.  That is why you have to listen to that standard spiel when calling a call centre - they record the conversation and *must* tell you they are doing it.  There are serious criminal penalties for illegal wiretapping.

This is now getting a little OT but what you're saying is still not correct.

 

As I mentioned above under NZ law a call recording is legal providing a single party is aware that the party is being recorded. If you're recording a call for your own personal use you do NOT need to inform the other party that the call is being recorded.

 

If you're a business user recording calls then the privacy act will very likely apply to call recordings and more importantly their storage and access to them. It's for this reason that companies typically make IVR announcements advising that call recording is occuring because there are lots of potential implications if you don't advise people or don't have a policy around access to an use of these recordings.

 

The "older law" you refer to is the Crimes Act 1961 of which section 216B applies to call recording and subsection 2 grants the exemption if you're a party to the call -

 

216B Prohibition on use of interception devices

 

(1) Subject to subsections (2) to (5), every one is liable to imprisonment for a term not exceeding 2 years who intentionally intercepts any private communication by means of an interception device.

 

(2) Subsection (1) does not apply where the person intercepting the private communication—
(a) is a party to that private communication

I think it got mentioned in a previous post .. have you swapped the cables that connect up the Fritzbox ?  A dodgy cable could cause a truck load of retries/error correction and tank your performance.

Those speeds definitely don't look right @BuckoNZ. You should be getting around 90-100Mbps download and 15-20Mbps upload with our standard fibre connection.

Can you PM us with your customer number, address, and date of birth so we can investigate.

Cheers,
^BRM
