AX1800 - 300Mbps in, but only 100Mbps out

[Chris_Cuomo]

Windows 10, Spectrum 300 Mbps internet via ES2251 modem

• I've verified the firmware is up to date. 
• I've checked the drivers. 
• I've power cycled it and the Spectrum modem.  Multiple times. 
• I've bought new Cat6 cables. 
• I've tried more cables.
• I swapped the cables to different ports
• I've gone under Device Manager > Network Adapters > Realtek PCI GbE Family Controller > Advanced > Speed & Duplex > Set it to Automatic and  also tried 1.0 Gbps Full Duplex
• I did the same for Device Manager > Network Adapters > Realtek PCIe GbE Family Controller

Still, I get about 360 Mbps when I go direct from the Spectrum modem to the ethernet port, but only 94 Mbps when I go through the router.

I've spent hours talking to the outsourced tech support (getting disconnected twice) only to finally be told that 100 Mbps is the most that can be obtained from any one of the WAN ports.  I see lots of people are having the same problem, but every solution seems to make no difference.

Before I return this router, is there any way to solve this problem?

[Chris_Cuomo · Accepted solution]

Well, I've again tried resetting everything.  Tried even more CAT6 cables.  Disabled QOS on a co-workers suggestion.  Still I get only 100 MBps.

At least when I return it, I can feel satisfied that I tried everything I could.

Which router model? AX1800 is a speed, not model!

There are no AX routers with only 100 Mbps LAN ports

[Chris_Cuomo]

R6700AX is the model number.  Sorry about that, it's so much smaller print on the box.

hello Chris

I saw this question of yours here yesterday

and looked up your Spectrum (Sercomm) ES2251 modem.

it has a 2.5GbE port, and auto-negotiates its speed 10,100,1000,2500.

meantime while I was looking it up, a reply arrived here for you.

I decided to afford "forum etiquette" and not interrupt.

but it seems nothing further is forthcoming.

also meantime, I see you've reposted the question.

maybe it could be said, unsurprisingly you've reposted.

but only to be greeted with scowling from yet other forum members for having done so.

so I'm doubly reluctant to contribute anything to this Question, I hope you understand.

...except to suggest you can check your R6700 User Manual

for the ports' LED color-speed meanings

then for a test, temporarily cause an ethernet loop by plugging that router's LAN to WAN

and check if it shows only 100Mbps that way

in which case, possibly your new router is faulty.

@et al

carry on

If my post showed up twice, I have no idea how that happened.  I only posted it once.  Here's the package of the router I received from Amazon.  I wasn't really expecting a plain brown cardboard box instead of retail packaging, but wasn't too immediately concerned.  Now I'm wondering if I ended up getting a refurbished model that wasn't fully refurbished.

The R6700AX does have four Gigabit Ethernet LAN ports, and a full Gigabit Ethernet WAN port.

In case you end on just 100 Mbps, review your cables. Gigabit Ethernet requires four working pairs, so eight strands of copper, properly crimped of course.

If your wireless does and out on 300 Mbps only, consider to replace the wireless clients for something more decent. 

An average mobile computer does come today with 802.11ax Wi-Fi 6 client, like an

• Intel AX2nn Series, 2x2, 160 MHz, 1K QAM, 2.4, and 5 GHz bands, max speed 2.4 Gbps

To be future-proof, look for a Wi-Fi 7 client. Devices equipped with e.g.

• Intel BE202, 2x2, 160 MHz, 1K QAM, 2.4, 5 and 6 GHz bands, max speed 2.4 Gbps, or the
• Intel BE200, 2x2, 320 MHz, 4K QAM, 2.4, 5 and 6 GHz bands, max speed 5.8 Gbps.

Modern eco-friendly packaging that is, and the eggs-box-like cardboard insert.

Instead looking on the packaging, what does the router itself say, model label, et all - and last but not least, the Web interface.

Somehow I'm under the impression, you got an very inexpensive router, like an R6020 instead - and not an R6700AX.

Post pictures of the effective router (both sides, including lower side view), the Web UI, ...

Have you bought a refurbished unit from Amazon? Suspect fraud ... some Amazon customer has returned an old device in an R6700AX box - and the poor or non-existing return logistics hadn't catched it.

I received a Netgear modem in that sort of packaging years ago.

Maybe it is a European thing.

No, the new industry de-facto standard worldwide, pretty new back at that time however 8-)

The only recent packaging I have seen from Netgear (last year), was the "NAS" version with all the usual ecohorrors in the way of printing inks.

The "paper" insert certainly replaced plastic foam a whole back.

Making devices themselves out of bamboo rather than plastic never caught on widely.
