San Gabriel, CA | Download slow with Router, fast directly connected to modem Hi all,
I have cable internet. When directly connected to the modem, I get 30Mbps down, 3 up. But when I hook up the router, I get around 4.5Mbps down.
We do have 2 computers hooked up via ethernet, and another 2 devices on Wifi. But I made sure none of the devices were using bandwidth.
Our router is WRT160N v3.
Any ideas? Do I need a better router? Thanks |

Most likely yes. Your router is underpowered for this task. |

San Gabriel, CA | Thank you, I was wondering if you can suggest for me a router that would work at such speeds? I am so lost on current technologies. Can Wifi go that fast? What about wired? Hopefully not too expensive, something basic is fine, maybe under $100? Thanks |

I did not ask but you are testing using wired port of the router right? If your testing over wifi, the test might be impacted by nearby interference and or issues with your laptop wifi adapter (not all deliver top performance). My search over internet indicates Wifi to LAN delivers about 35Mbps max. on this device. SmallNetBuilder indicates it supports at least 60Mbps LAN-WAN, WAN-LAN over wired ports. So, if these numbers are correct, I will retract my words on that it is underpowered (for your Internet connection) but perhaps you are not testing correctly. |

San Gabriel, CA | Thanks for the reply. I was talking about my speed test (4.5Mbps) when I am connected ethernet wire to router... Wifi speeds are similar too. Not sure why it's so slow. I think it used to be faster. Perhaps I have too many devices? |

Are you doing these tests back to back (with and without router) or at different times? Sometimes the test server you have connected is congested giving different results back to back. You might need to repeat the test a few times. Also make sure your other LAN hosts are not busy using the internet while you test. |

Don't give up yet. It seems you should get a little better than 4MB/Sec. I have a nine year old Netgear FVS318 that still provides 7Mbps from an advertised 10 Mbps connection.
Check your ISP to see what your advertised connection is, and shoot for that. If you're using Time Warner's Turbo Boost, you can get higher than advertised bursts on file transfers and speed tests.
Then, for testing, disable wireless in case you have some freeloaders or other unforeseen activity affecting your pipe. That will eliminate any possibility of wireless affecting the tests.
If you can borrow one, try putting a switch(SWITCH, not a HUB) between the modem and the router's WAN port. Sometimes MTUs aren't properly negotiated between the modem and router, causing throughput issues. A switch may resolve that issue.
I noticed that problem with older routers, not sure if it's still an issue, but it doesn't hurt to try.
Be sure to use your wired connection to test, and disconnect all cables except your testing system. Be sure all browser tabs and programs are closed down except the one you're using to connect to the test site.
Duplex mismatches can also cause slowdowns.
Another test is to disable SPI. That may help boost your throughput at the expense of not mitigating DoS attacks like PING of death.
A WEB100 server can provide some diagnostic information that can help identify causes like bad cables, poor connections, congestion etc. See »nitro.ucsc.edu/ |

Recently, Java based test server here were not very reliable. You could try Flash based test. Also try »www.SpeedTest.net. It may pick up close by test servers so you might get better bandwidth.
Again, it is important to perform direct cable modem and through router tests back to back and through wired ethernet for a more realistic comparison. |

Our router is WRT160N v3. 1 .. what's the make and model of your cable modem?
2 .. who is your ISP?

Hi everyone,
Thank you very much for the replies. It seems the problem fixed itself. I just pished the pin hole in the back of the router and then now the speed goes up to max. Who knows??  |

All problems with IT can be fixed with a reboot  Till the next time it happens...
