I've recently upgraded from a 10mb download speed con to 15 mb.

When i have 10 mb wifi was just fine and i was downloading over wifi at 1.1MB/s.

Now when on 15mb plan, some how my wifi speed have decreased dramatically and i only get around 400k/sec while downloading over wifi.

When connected to ethernet cable it works just fine at 1.7MB/s.

My router is Asus 604g.

How come that after upgrading my plan my wifi speed got slower?

I assume the line from the ISP may have a fault - I suggest you try a continuous ping from your computer to an external IP like and see how many packets are dropped. – Dave Sep 13 '12 at 14:16
i just did, none were lost, although time of ping did change from 85ms to ~300ms – Nadav Sep 13 '12 at 14:20
If you want to troubleshoot this properly, you need to use a controlled download, preferably on your LAN. WiFi speed has nothing to do with equipment outside of your home/office. When you switched services, did you switch wifi equipment? – horatio Sep 13 '12 at 14:23
It depends on where you are in the world, but from the UK it takes ~23. It sounds like there is a fault on your line. I would also do a tracert to see if you can see a jump on the hops at a certain point. Not very reliable but on occasions conclusive. – Dave Sep 13 '12 at 14:23
Or, your new service means you no longer have a prioritized line? – Dave Sep 13 '12 at 14:24

Contact your ISP for this, for further investigate, If you have not made changes on your modem/router or firewall setting on router/computer, there is no reason why you wont get full speed.

Try some speed test sites, and i assume your ISP has speed test tools also, here on israel we usually check against the ISP, he tells us go to and check the speed, if the speed is not as we pay, and there is nothing wrong, they bring a technical guy to check the line.

Since no changes were made in the router modem or computer, this questions can be answered by them.
