Sagemcom Fast 5364 Not Issuing IP Addressess Needs Regular Reboot

Team Player

Please could I get some help with our TalkTalk Wi-Fi Hub?


For the past week we've been having issues with the Sagemcom Fast 5364 not Issuing IP Addresses. Which can only be resolved by rebooting the Router every day sometimes more.


I think it might be a fault with the Router itself because we have a solid connection to the internet with 68mbps download and 19-20mbps upload speeds.


WiFi signal is fantastic, we have 3 Tablets, 2 Phones, 2 Smart TV's and Sky Q running. All were working really well until a week ago. The problem is really apparent with the PlayStation 4, which is connected via Ethernet directly to the Router.


I get an error message saying "Failed to issue IP address in time" once I reboot the Router the issue resolves for a while.


I've had the PS4 looked at by engineer, apparently there is no problem with the console as I connect directly via Ethernet. had Sky Engineer check our Sky setup and again they report no issue with that.


I wonder if it would be possible to get a replacement Router please? As both engineers have said it is highly likely there is a fault with Router itself.


The Firmware version: SG4K1000260


Thank you

I have asked one of TalkTalk's OCEs to pick your thread up and investigate it for you.

The forum is not real-time 24/7 support, so depending on how busy they are & how many are working at any one time, this can take 24 - 48 hrs (excluding weekends & limited cover on Bank Holidays). Alternatively, you can call the call centre or use online chat. The posts are responded to in time/date order, oldest first. So the fewer entries you make on your thread now, the sooner they will pick it up.

To save yourself time, please make sure that your community profile includes your first & last names, broadband phone number & if possible an alternative contact number. This can be done by clicking on your Avatar picture then click on "My Settings" followed by:-

Personal Profile > Personal Information

Otherwise, TalkTalk will not be able to tie up your forum username to your broadband account. Only you & TalkTalk have visibility of your details.

I am not employed by TalkTalk, I'm just a customer. If my post has fixed the issue, please mark it as the Best Answer.

Hi bill80


Sorry to hear you're experiencing problems with your router. Can you initially try resetting your router to factory default settings and then retest. If this doesn't resolve the issue please let us know and we can look into it further

Hi @OCE_Chris 


Thanks for this. I've just reset the Router and everything looks to be back up and running again!


Fingers crossed...


Thanks again

Hi, @OCE_Debbie @OCE_Chris @KeithFrench 


Thanks again for your help, hopefully I'm not tempting fate. But ever since I did the "pinhole reset" my connection is stable again. Excellent speeds too!


Ran a Speed test using Speedtest by Ookla Android app. I'm getting consistent 69 - 72Mbps DL and 18 - 19Mbps Upload.


Very happy indeed. When I was experiencing issues I read about Firmware updates, do you install them in the background or is it something the user/customer has to check periodically?


It's great to have everything up and running again. I am still amazed at how much of an impact having an internet connection has on our day-to-day life. If it goes down it's like losing a limb!


Hope you have a great weekend! 😁
