Hi All,

I have been having an ongoing sagas with my router speed - ref to https://www.geekzone.co.nz/forums.asp?forumId=39&topicId=214701

Lately the download speed dropped to 220mbps. After speaking to Spark support, they sewnt their own router - their Huawei - and got speeds of 900+mbps

So I conclude the problem rests with my router - I have also tried the leads that came with the huawei (WAN and LAN) and still no change in the speed of my Asus.

I am planning to do a factory reset tomorrow. But wondered if anyone could shed any helpful suggestions why my router would slow down like this? Is this a symptom of a long slow death?

Cheers as always,

A bit of additional info:

Tested via wired connection

My PC is only device connected at time of testing (WIFI is off)

No known major downloads occurring at time - to be honest the Huawei was gioving 900+ regardless anyway.

If you are posting regarding DSL speeds please check that

you have reset your modem and router
your PC (or other PCs in your LAN) is not downloading large files when you are testing - you are not being throttled by your ISP due to going over the monthly cap
your tests are always done on an ethernet connection to the router - do not use wireless for testing
you read this topic and follow the instructions there.

Make sure you provide information for other users to help you. If you have not already done it, please EDIT your post and add this now:

i suspect your router is the issue and it just cant handle it.

just because you spend $400 on a router doesnt mean you will be able to max your connection out. may of these hi end devices struggle with WAN to LAN throughput.

So what sort of router can handle it? What is your recommendation?

Maybe there was a firmware update that disabled CTF look through the settings and I believe it's on the LAN page under the Switch Control tab and enable NAT acceleration.

Thanks for the advice.

On that page

Enable jumbo frame - Disable

NAT acceleration - Auto (the only other option if disable)

Since the HG659b has been sent, is there a reason you do not wish to use that device?

It's crap!

Have done a factory reset - speed is up to 340 now.

Surely if my router was broken I would not get this sort of behaviour - would I?

its obviously not that crap if its getting over 900mbps

the low speed you are getting doesnt mean your router is broken, it just means its either underpowered in that department or has some setting in it that hamstring it.

You say the free router that delivers over 900Mbp/s is crap and the one you paid $400 for is good and delivers 350Mbp/s

What am I missing here?

try turning NAT Acceleration to off and see what happens

"NAT acceleration is a feature that is available on Asus branded routers. It is also known as hardware acceleration in some cases by other branded routers. It can also be named as CTF (Cut-Through Forwarding) and FA (Flow Accelerator)"

kapitikarl: So what sort of router can handle it? What is your recommendation?

My recommendation would be the Spark supplied HG659b - it's one of the few devices on the market that can handle 1Gbps/1Gbps and not break a sweat.

What are your reasons for not wanting to use this? The misconception that because it's supplied by an ISP it must be useless is very rarely the case.

Yeah I have my reasons for not using the Huawei. But given I don't have much time, I would like to focus on troubleshooting my Asus.

I tried the NAT acceleration suggestion - switching it off - the only effect it had was stop connection altogether. I gave it a good 10 minutes before I reverted back but the internet light stayed permanently red.

Going to call Asus - wish me luck :s

Please keep the suggestions flowing in. It is appreciated.

Think you mean ' here '

The problem is clearly the router and you can solve it by using the ISP provided router

You are the one that introduced the problem in the first place
