A decent router should almost never need rebooting. I've seen Ubiquiti Edgerouters with up times well over 6 months no worries at all. 

If you are talking about a modem router, it is actually detrimental to reboot them too often as ddDLM can think there is an issue and start messing with your line unnecessarily. Running any modem/router, especially a modem on a UPS is a good idea. 

If you do have to often reboot your router, it's probably either crap, or has an issue. 

Hi, what kind of router, I use a lot of Fortigates and Mikrotiks, cant remember when I last had to reboot one because it went awol

Everything needs a reboot every now and then.  I've seen servers that were online for 500+ days but performed like dogs and would have sprung back to life had they been rebooted, but by that stage everyone was too scared what would happen :)

I forgot to mention I'm on fibre if that makes a difference. 

I only reboot mine if I make a change.

It's just a TP Link Router.

Previously had a Netgear Nighthawk that would need rebooting frequently to fix WiFi issues.

i never reboot mine, i avoid it like the plague.

99% of the time it's not a router issue.

I do run enterprise grade wifi and routing gear though...

Nah. My Fritzbox is always up because it's on a UPS. I think it rebooted last time there was a firmware upgrade. You can reboot it if you like though.

Totally conflicting advices here - what is the OP going to think?

He's going to hopefully think that their is no "one answer" and the reality is it depends on a bunch of factors.

However to summarise for him and make his life a little bit easier:

• When using a DSL/VDSL modem/router, avoid reboots as it may cause DLM (Dynamic Line Management) to think their are issues with your phoneline, and thus lower speeds to attempt better stability.
• When using quality enterprise/prosumer equipment (e.g. Cisco, Microtik, Ubiquiti, Fortigate, Sophos, etc), you're unlikely to ever NEED to reboot the router, but unless it's on DSL it won't hurt.
• When using home/crap equipment (even very expensive crap *cough* gaming routers), such as Huawei, Netgear, Dlink, TPLink, you may find that a reboot does help every now and then, but it's really going to depend on the combination of the product and it's firmware. Some is okay, some is awful. 

My Spark HG630b says it's been up for 123 days.

If there is a problem that rebooting the router might fix, then I reboot it. But when I have network problems and everything outwardly looks OK then I usually work my way up the line from the device, the network adapter, the cable, and then the router, and so on.
