Tags: #XE75
Model: Deco XE75  
Hardware Version:
Firmware Version: 1.1.11 Build 20230302 Rel. 51700

My Dexo XE75 limits the speed to under 100mbps often, the temporary solution i found is to unplug fiber ethernet cable and replug it. This is so annoying since it happends so often, at least once a week or more. Any true solution for this issue or firmware update?

Hi, welcome to the community.

Have you ever tried to replace a new internet cable to connect the main Deco XE75 to the ISP modem?

And may I know who is your internet service provider and what is the model number of the internet modem?

When you noticed Deco XE75 dropped to 100m/s again, please try to unplug the main XE75 and plug a laptop into the modem to make sure the laptop could still get 1G speed.

Thank you very much.

Best regards.

No, I haven't tried to replace cable since my deco is new and I'm using the cable provided in the box. I can try to replace it next time. I will also check the speed on the main deco when it happens. 

 

Internett provider is GlobalConnect Norway. Its a fiber connection so i don't have modem but I do have a router between deco and media converter. Also i have dynamic ip. Router is Zyxel AM3100.

 

I do have two networks in my home, one is using deco x60, that's works fine. Only having issue with deco XE75.

Thanks for the update. I will wait for your further test.

By the way, is the current network layout like this:

So just an update. I disabled SIP ALG and UPNP in XE75. Since then I haven't had any issues. Maybe it's caused by bad implementation of SIP ALG or UPNP?

Thanks for the update. it's good to know you have found the solution.

I did see it mentioned here to turn off the UPNP and SIP ALG when the speed is low.

Troubleshooting: Slow Internet Speed with Deco Devices

It did not explain why and I haven't found any possible reasons on Google either.

I will pay more attention to similar cases later.

Thanks again.

Best regards.

i got this problem with my isp by pppoe too, so i will also disable sip and upnp, if really due this reason, then it should can be fix by a new firmware update.

 

thanks.

  @Pakee Just made an account to confirm that this worked. I had to unplug and replug the cable. I think TPLINK should make a firmware update.

Anyone not finding SIP or UPNP, you need to have the deco configured as router and not as an access point.
