Reserving IP Addresses on TalkTalk Sagemcom Fast 5364

Hi.  I got a firmware update overnight which gave me the ability to reserve an I.P. address.  I've reserved sixteen I.P addresses but it's a bit flaky as sometimes the router will assign a differing I.P. to a device I've put on the reserve list.  Also the router won't allow me to determine the I.P. range the DHCP spans; if I put in 192.168.1.100 - 192.168.1.199 and then hit save the router always defaults back to 192.168.1.10 - 192.168.1.254.  I've got a repeater on 192.168.1.200 which is technically in the range of the router's DHCP (I could put the repeater on 192.168.1.9, but it's unlikely I'll ever have enough devices to get up to 192.168.1.199).

 

All in all, I think the firmware is still full of bugs and nowhere near up to the standard of even a £19.00 TP-Link router.

Hi Griff,

 

Which firmware version is your router currently running?

Hi, tried a few different settings & found that I can set my router DHCP to 192.168.1.3 - 192.168.1.254 & it seems to keep the settings even after a reboot or 2. I've got AP's at 192.168.1.3 & 192.168.1.254, these have manually set IP addresses but I've also added them as reserved addresses. I have also reserved addresses for other devices, I picked addresses they weren't already using & when I rebooted the devices they picked up the new reserved addresses. The firmware I'm running SG4K10002808t won't allow me to reserve an IP address outside of the DHCP range although the manually set AP 192.168.1.3 works perfectly whether it is within or outside the set DHCP range. Hope this gives you some pointers to sort your issue.

Hi,

 

The router does what I want after a fashion; it's allowed me to set the DNS to that of my Pi-Hole which is a big plus.  My A.P. on 192.168.1.200 has its own IP so that doesn't need to be reserved, but there's always the potential of a clash in the unlikely event the router decides to try and specify 200.  It would be nice to be able to specify the I.P. range but, so far, nothing's gone wrong yet and fingers crossed it won't.

Hi Griff, if you also reserve the IP address 192.168.1.200 (even though it's a manually set address) then you can ensure the Hub/router (DHCP server) will definitely not try to hand out that address

Yep.  That'll do the trick.

Thanks for the tip.
