You should have no issue reaching that speed unless your router or onboard lan is running at 10mbps instead of 100mbps.

Of course if someone is downloading while you are doing a speedtest it will affect the result. Make sure you're the only one using it at the time.

I think that your ISP hasn't upgraded you at all.

Try www.speedtest.net for speed tests as well.

I knew about the factor of 8.

Speednet gives me the same result.

My LAN displayed as 100mbps in Win 7. Why is my router limiting me at 33mbps.

Can you explain what 10 and 100 mean. I thought is what internet/LAN. Does it mean I should be limited at 10mbps and that I am lucky to reach even 33.

100mbps is local network speed. Your ISP can only supply you ~30mbps, as is evident by FTTC (Fibre to the cabinet) - it means your local street/wherever has shared bandwidth.

My wireless connection says 300mbps, but my speedtest.net speed is 10mbps/1mbps. That's my connection to the internet. 300mbps is anywhere between computers in my home.

If everyone except you stopped using the internet your speeds would go up.

Welcome to over-subscribing and under-performing ISP's.

Most likely the bottleneck is not the routing that is occurring but the built in firewall. The routing should be near line speed, however the maximum through put of the firewall may be limited to 50 mbps subtract the typical 25-30% overhead from that and your close to the speeds you are seeing. Even Cisco, Juniper and Sidewinder Firewalls have this overhead.

You can Virgin Media in the UK do.

Also not all of them devices have that overhead specifically ones which do not even employ a firewall feature.
A fair bit of misinformation in this thread to be honest.

I can't guarantee it would work but I see that the router is fairly old and only supports Wireless G technologies.

It may be possible that the routers processor is too weak but as I said there's no guarantee.

Also the 100Mb's you see on Windows 7 is the negotiation speed for the port on the router and your PC.

Welcome to over-subscribing and under-performing ISP's.
If his modem directly gives him 60Mb speeds on a speedtest then it is clear that the router is indeed somehow bottlenecking. This could be due to a huge number of things.


Cisco devices are my absolute speciality with Networking but I'm knowledgable with home broadband and in general as my company provides managed data services.




TLR, a new router may solve the problem but it's a 70% chance it won't.

A new router will resolve the issue and after reviewing http://www.smc.com/files/AI/DS_WBR14G.pdf it should help you identify what is the cause.

Dig through the router settings and see if there is a QOS setting that may inadvertently turned on. If it is on, turn it off and try again.

I didn't think of QOS and Firewalls. Try turning them off as said above.

Thanks a lot for the feedback guys.

I fully agree from the modem/PC test, that the router is somehow causing the issue here. After reading your post I conclude the following:
  • The router should technically support internet speeds up to 100Mbps.
  • The reason why it doesn't is not trivial
  • The cause could be the processor being too weak
  • The cause could be the firewall or other router function that prevent maximum speed
  • A new router would most likely resolve the issue but there is a chance it doesn't.

Could the modem to router cable be responsible? I try 2 cables but they look thin and cheap to me.

It is possible that cable could be the weak point.

But still if a cable is in poor state usually it either works or it doesn't not halfway and sort of work.



The router does not have to support speeds unto 100Mbps just the ports do

You could try ringing your ISP and getting an engineer out, usually they are pretty knowledgable enough.

Just tried that. No luck

Called my ISP when the problem first appeared. Talked to a retard that knew less about networking than I did.

The cable is in a good shape, it appears to be cheap and not shielded.
