Arcadyan version of the Telstra Smart Modem Gen2 (LH1000) throttling traffic between WiFi and LAN

Answered

Has any one else noticed that the Arcadyan modem throttles traffic between WiFi and the LAN. As proof of this I did three test between Iperf3 server and Iperf3 client. See results below

Using WiFi for both client and server does not give a true reading of the WiFi speed. Doing the same test on the DJA0231 modem results in a speed of 700Mbps between Iperf3 LAN server and Iperf3 WiFi client.

Re: Arcadyan version of the Telstra Smart Modem Gen2 (LH1000) throttling traffic between WiFi and LA

Finaly tracked down what was causing the throttling. I appears that if any port forwarding rules are set up the modem will throttle traffic between WLAN and LAN.

 

No port setup forwarding 552 Mbps download 489 Mbps upload

The modem also appears to throttle traffic between a booster and modem's WiFi irrespective of whether booster is connected to modem by WiIFi or LAN cable. See images below

Server and client connected to booster' WiFi

 

Server and Client connected to booster. Booster connected modem by LAN cable

Factory reset of modem fixed the throttling, but when settings were rested from a backup file the throttling returned. When I have a spare three hours will reset and set up modem manually.

 

Restoration of backup also resulted in connection to maintenance failing resulting in phone no longer working and probably future firmware updates no longer being delivered.

Re: Arcadyan version of the Telstra Smart Modem Gen2 (LH1000) throttling traffic between WiFi and LA

Hi - interesting results regarding the Port Forwarding influence. I have the impression that the iperf3 measuring tool has variable results from vendors who incorporate it in their Apps and even its raw native standalone mode (on the French site) it displays varying behaviour within Client and Server modes. Based on my experiences, for LAN-LAN testing it appears to generally show higher speeds on tests where the sample size being transmitted is larger. Haven't been able to draw any definitive conclusions.  

 

In raw mode, doing LAN to LAN tests between two PCs on a cascaded Arcadyan (server PC) to WAN port of DJA0231 (client PC) separate subnets configuration , I notice the program seems to auto select a variable test data package - no idea of what determines the size. It appears to me that the WAN port of secondary modems has a limiter placed on it. 

 

1. Client PC on DJA0231 to Server PC on Arcadyan - 11 Samples

(a) Upload Data via WAN port -  Total 66.4 MBytes - average Speed 55.7 Mbps

(b) Second test - 108 Mbytes with average 90.1 Mbps

(c) Third test - 93.1 Mbytes with average 77.9 Mbps

 

2. Same test using Fritzbox 7490 in lieu of Technicolor modem - 11 samples

(a) Upload Data via WAN -  Total 176 MBytes - average Speed 148 Mbps

(b) Download Data on LAN port 713 MBytes with 597 Mbps

(c) Second download test - 728 MBytes with 610 Mbps

 

3. Same test using Sagemcom F@ST 5366 in lieu of Technicolor modem - 11 samples

(a) Upload Data via WAN port  -  Total 79.8 MBytes - average Speed 66.8 Mbps

(b) Second test - 112 Mbytes with 93.7 Mbps

(c) Download Data via LAN port - 784 MBytes with 657 Mbps

 

4. Similar test results on Telstra V7610 showed -

Upload via WAN port  - 206 Mbytes with 173 Mbps and Download via LAN port - 769 Mbytes and 645 Mbps

 

5. I recently loaded H.E.- Net's ( US ISP) Internet Tools from the Apple Store as it includes iPerf2 and iPerf3 for Wi-Fi testing on my iPad4. This App allows you to define the size of the data test package to be used for the Wi-Fi test. I chose iperf3 with 300 Mbytes (48 samples) . HP Netbook PC as iperf3 Server linked directly to Arcadyan Modem ( no Port Forwarding) with iPad4 as  iPerf3 Client using its 1x1 SS 5Ghz band ( max theoretical 150 Mbps).

(a) Upload test at 1 metre , 5Ghz - 294 Mbytes with 51.5 Mbps

(b) Second test  at 1 metre - 294 Mbytes with  75.4 Mbps

(c) Third at 2 metres - 294 Mbytes with 69.8 Mbps

Re: Arcadyan version of the Telstra Smart Modem Gen2 (LH1000) throttling traffic between WiFi and LA

@Mkrtich 

 

Interesting results of the upload speed being throttled? How long after the modem booted up did you do the tests? The reason I asked this question is that I only noticed throttling after second modem had just bootted up and connected to primary modem. See results below.

Would be interested the Iperf3 speed results of iPad with a port forwarding rule set up. Surprising result the reading close to the modem is lower than the others. Would be interesting to see results if modem's WiFi power level was set at a lower setting.

Re: Arcadyan version of the Telstra Smart Modem Gen2 (LH1000) throttling traffic between WiFi and LA

Hi - Envious of your results. I must have gremlins in my network which are encouraged by my somewhat outdated equipment. I have found iperf 3 to be a good tool but for me it gives unexplained results particularly using the Reverse command.

 

The first two results in your post indicate two modems connected - ARC Client 192.168.0.241 to  AGO Server 192.168.178.4 (Fritz!Box IP?) @ 884 Mbps TX/RX and 796 Mbps TX/TX and 2 Retransmits (Retr) from Server - clean network - great result. 

 

Your third result is done on one modem only - both devices are connected to same IP address range - the modem hosting the AGO device. The Reverse test  result is 39.2 Mbps TX and 38.9 Mbps RX. I get the same pattern when I use a Reverse command, although I use iperf3 -R -c 192.168.0.244 and get the same result as when I use your variant iperf3 -c 192.168.0.244 -R. So it raises the question is it the iperf3 tool or the Arcadyan. I get heaps more Retransmits on my Reverse readings perhaps indicating another problem in my network or equipment. It didn't make any difference on my tests - I reset the modem and the PCs and redid the tests shortly afterwards reboot and then during the hour of frustrated testing that followed with replacement cables which made negligible difference. I suspect my old HP Netbook may be a contributing culprit.

_________________________________________________________________________________  

 

I hadn't done a single modem test before, so I thought I should start there as a benchmark.

Summary of my testing with one modem only :- 

 

Jetson Nano PC 192.168.0.244 on LAN4 of Arcadyan and HP Netbook PC 192.168.0.214 on LAN 1 - they are on different controller pairs inside the modem which lead to the integrated internal SoC Ethernet LAN Switch.

 

1. From HP Netbook - Using iperf3 -c 192.168.0.244 command

HP Client to JNano Server -  609 Mbps TX and 609 Mbps TX - no Retr. [ other results 564 Mbps and 465 Mbps with no Retrs] 

2. From JNano - Using iperf3 -c 192.168.0.214 command 

JNano to HP Server - 141/142 Mbps, 138/139 Mbps and 144/143 Mbps TX/RX 

 

3. Using the Reverse command as Prefix to IP address from the HP Netbook always involved Retransmits

(a) Sender JNano Server to HP Netbook shows 141 Mbps TX with 27 Retrs  and 141 RX No Retrs.

4. Using the Reverse command as Suffix to IP address from the HP Netbook always involved Retransmits

(a) Sender JNano Server to HP Netbook shows 139 Mbps TX with 22 Retrs  and 138 RX No Retrs.

 

So, there seems to be some perhaps Firewall inspired filtering/inspecting and slowing down of incoming datagrams to the Arcadyan LAN ports on my configuration. I can't make the statement with confidence as I can't rule out other equipment issues.

Posted the wrong configuration in to my post. Should have been.

 

AGO Media IPv3 Server -----(LAN) LH1000 (LAN)----(WAN) DJA0230 (LAN)----Asus Laptop IPv3 Client

 

I see a couple of retries when using iperf3 -c -r  with the above configuration but non when both devices are connected directly to LAN ports on the main modem.

Telstra Smart Modem

Plug in and connect in minutes. Smart.
