I know it's a first world problem, but has anyone had any luck getting a Linksys E4200 to route LAN to WAN at faster speeds than 100mbps over a tagged UFB connection?

I've confirmed the linkspeed between the E4200 and the ONT is gigabit without any duplex mismatches, and have also confirmed the PC's I'm testing with can do well above 100mbps LAN to LAN so know it's the E4200's causing the issue

I've tested with TomatoUSB Toastman and Shibby, both top out at 100mbps. I've only noticed it since going to a 200mbps plan, and don't really want to go back to the stock firmware and an untagged port, but will if I have to.

Anyone tried another 3rd party firmware and had better luck?

Cool.

Poor you can ONLY top 100Mbp/s

Check the duplex settings and negotiation link speeds.

Sad face, I am balancing 2 VDSL lines one at 32Mbp/s and other at 40Mbp/s

As above, auto-neg 1gig confirmed, no apparent duplex mismatch's, also tested with a switch between the ONT and router just in case.

I guess I'm highlighting a potential issue for others running a similar setup once these 200mbps plans become more common, ie that not all routers will hack it

And in the interest of accuracy, it was a little faster than "ONLY" 100mbps :p

That's still pretty damn usable! I 'only' get 69/10mbps on my VDSL

Stop, Stop now.

Haha, Whats the results with another device?

I don't have another device, only other person I know with 200mbps UFB got it installed today and also has a e4200 + TomatoUSB on my advise, same issue.

I'll have to get the port untagged and revert to stock linksys firmware, or get a small managed switch to do the tagging.

So you have confirmed its not a Chorus issue?
I have come across a few similar to this.

I've only confirmed that I'm on the correct plan, haven't logged a fault. But you've given me something else to check, I'll try find some software PPPoE dialer and tag on my PCs NIC, should work.

Most late model intel NIC's will VLAN tag.

It'd be interesting to see what the performance is like without PPPoE - PPPoE is a major stumbling block as speeds get faster.

also what's router CPU load like at 100M? I remember my RT-N16 on my 100M UFB was like 6 to 7 in tomatousb that made GUI somewhat unresponsive when under load and running close/at to line speed.
just make sure you have plenty of head room with router hardware.

That's very interesting, during a speedtest the system load jumps up to 0.85 (idles at 0.02), but that's the best resolution I can get with it refreshing every 0.5 seconds. The GUI at that point does get sluggish, so it's probably getting close to, or is hitting a system load of 1 during the test

TomatoUSB mustn't be making use of the right drivers for the chipset. as the default firmware is good for close to 700mbps LAN to WAN

I do know someone else with the same provider and she is getting 190+ mbps on the 200mbps plan with a microtik I believe, I don't know which one though and I'm sure she won't give it up for me to test!

Is it the v1 or v2 E4200? The v1 will max out at about 120Mbps unless someone has come up with some seriously efficient third party firmware for it. Haven't tried the v2 but I hear they are better...

It is the v1 as I don't believe v2 supports TomatoUSB, I bought it a few years ago. Reading other forums etc it seems to be a common problem with this router and 3rd party firmware which don't support FastNAT, everyone seems to be OK on stock firmware as it does.

Any of the Gigabit Mikrotik devices will easily handle 200Mbps. Even a ~$60 RG750GL will route 900Mbps with 1500 byte packets, but the impact of small packets or firewall rules will be very significant as it's a very low spec unit.

Actually, I believe Tomato does support FastNat, at least in Shibby builds through the bcm_nat module.

You lose QOS, iptraffic etc of course.

All the latest generation of broadcom based routers will route Gigabit at wire speed, so they shouldn't have any issues with 200Mbps.
