(SOLVED) FiOS gigabit... Suddenly super slow download speed

Have had FiOS gigabit for 3 weeks at present. It worked great the outset two weeks, was getting 200+ Mbps download and upload.

Suddenly last calendar week my download speed has slowed to a maximum of 12mbps and a minimum of 2mbps depending on what site I'1000 testing it on. My upload speed is still insanely fast though.

Already tried rebooting router, ont, etc.

To complicate things im using my own asus router and then Verizon won't provide any back up. Information technology'south a make new router.

At that place's no new devices on my network. Nil else has inverse. ..

Connect direct from ONT to your computer and examination the speed that way.

I've had this happen more than then a few times recently. Information technology'southward super frustrating just I'm able to reset my router a few times to get it moving again.

Have had FiOS gigabit for 3 weeks now. Information technology worked nifty the first two weeks, was getting 200+ Mbps download and upload.

To complicate things im using my own asus router and so Verizon won't provide any support. It's a brand new router.

At that place's no new devices on my network. Nothing else has changed.

Connect straight from ONT to your figurer and test the speed that style.

OK THIS IS Bizarre!

I connected my laptop direct to the ONT and got virtually 600mbps which is faster than I ever got.

I plugged my regular CAT6 dorsum into the ONT (the 1 that goes to the router) and now my speeds are dorsum to "normal" (286mbps download and 186mbps upload via verizon'south speed test)

Umm? And then just unplugging the cat6 cablevision and plugging it back in fixed it?

Could the cable being loose in the socket actually cause slower speeds? That's then bizarre. You would think if it's not continued in all the way, you would get no data, not just slower data.

Could exist a bad cable. If you take gigabit, why are your speeds nevertheless slow? I get like 930Mbps and ordinarily similar 940 Mbps up. 600 seems abnormal to me for gigabit, only I've merely had the service for nigh a twelvemonth. What router model do yous take? A 'new' ane ways zero, since y'all tin purchase a new 'older' router. CPU and RAM the router has can affect speeds, amongst other things.

I've had that happen, ordinarily with wifi.

Yeah I was hoping to become the full gigabit simply it's advertised as "up to gigabit" I guess.

I'm using an Asus AC1900.
»www.amazon.com/gp/produc ··· F8&psc=i

Information technology says it can get up to 1900mbps.

The cable from the ONT to my router is a cat6. The cable from the router to my PC is a Cat5E. But the cat5E should in theory be able to handle upwardly to 1000mbps?

Also the lan port in my PC is too a 1000mpbs land port.

In reality, I'm getting 286/186 wired at the moment and my wifi devices are getting 101/125.

Past the way, when I plugged my laptop into the ONT direct I used a Cat5E cable I had on hand and that got me the 600mbps straight from the ONT.

I guess the cat6 cable could be lacking - it's an amazon nuts brand which is cheap equally heck but has very very practiced reviews. I accept a spare one they sent me past blow I could try that i too I approximate.

Get-go off, that 1900 Mbps is the combined speed of the WiFi bands, and has naught to practise with wired performance. Your wired speeds should be around 900 Mbps connected straight to the ont. Either you have a faulty cable or your computer cannot proceed upward. Anything older than 2010 may struggle unless it was top of the line at the time. Updating network drivers and using an Intel network interface are also recommended.

As for the router, do NOT enable QoS as consumer hardware CANNOT handle it at those speeds.

Re: (SOLVED) FiOS gigabit... Of a sudden super ho-hum download speed

Non Fios routers have to have QOS off. Verizon will only assist if they can contact a Breakthrough router. I use quantum with its lan port feeding an OpenWRT router. Turn off quantum wifi and make certain your personal router doesn't use x.x.1.ten subnet for example x.ten.0.x. Verizon offers support to their router if downloads fail to go 500 Mbps downward.

As a reminder all Fiber GPON accept a 2.four Gigabit synchronous down link shared by multiple users (typically upward to 16-32 users). Fiber has one.2 Gigabit synchronous up link similarly shared past up to 32 users. If you share with peer to peer user they can easily fill up the link.

Internet is shared!!!

Keep in mind that anything over 250 Megabits / second is fast. Annotation pocket-sized monthly cost increase to go 1 Gigabit from 150 Megabits($30/month). If node is lightly used past other users yous may accomplish 900/900 at times.

Did yous remember to increment the number of buffers in your NIC to the maximum number of buffers that your NIC can back up? When I increased the number of buffers to the maximum allowed, my upload and download speeds increased quite a bit. This speeds things up specially if packets go far out of order. If there are more buffers, this can speed up your total bandwidth specially with TCP connections. This is because TCP tin can only process segments in each connection in guild. If a TCP segment arrives earlier than its normal order, it could be buffered if in that location are buffers available to concord it, or information technology could exist discarded and then subsequently retransmitted if there are no buffers able to hold it or if the NIC's or the operating system's buffering strategy for out of order TCP segments decides to discard information technology. TCP segments that arrived also early on tin only be processed once the TCP segment that was supposed to arrive before the segments that prematurely arrived finally arrives so that everything tin can be reordered to the right guild and so processed. Having more buffers therefore allows these segments to be saved for reordering. Increasing your buffers can let all Ethernet frames to exist held until the CPU tin can get around to processing them, and so information technology tin can preclude frame losses which can improve both TCP speed and reduce the number of lost UDP datagrams. I increased the number of buffers on my motherboard's Intel Gigabit Ethernet controller to its maximum of 2048 receive buffers and 2048 transmit buffers, and saw a massive speed increment. The but downside of increasing the number of retentivity buffers is that it consumes more than system RAM, but considering the number of gigabytes that modern computers take for RAM makes this tradeoff negligible.

If you are concerned nigh latency, lowering the number of buffers will not help at all. Yous will have to tweak your NIC's interrupt options if y'all want to favor lower latency at the expense of CPU utilization and connectedness throughput.
