Router signal dropping

I need help diagnosing and fixing my router problems.  This router has been used for quite a while now without issues.  I bought a new laptop that won't play nice with the router.

The router is a Linksys WRT330N with firmware v1.00.4

The new laptop is a Dell Inspiron 1545 with an Intel Wifi 5100 AGN 802.11N capable internal card with the lastest drivers.

The drop offs affected all computers on the LAN (2wired, 1wireless)

The wireless connection always stays strong with excellent signal strength and has a constant speed of 65Mbps

I have added the router's log file, or at least a small snippet of it.

From your logs it looks like your WAN interface has disconnected and then reconnected several times. Is this you unplugging it?

If not then it sounds like either the interface is going bad, you have a bad cable or the internet modem is dropping your connection for some reason.

If the port is going up and down on its own here is where i would start.

First reboot router and modem then if the issue continues try replacing the cable.


Also do the wireless clients get disconnected when this happens? Does this effect network access or just internet access?

the router's diagnostics were fine. the cable it seems is fine.  the modem seems fine.

the signal drops occur when the wireless laptop forces high speeds in the router.  is it possible that this is causing the router to 'get confused' and reset itself?  the router is draft-n and the laptop card is wireless-n...are they having problems communicating with each other at these higher speeds?

or is there a way to 'slow down' my laptop speed and see if that helps fix the problem.

again my router is a Linksys WRT330N and my new laptop is a Inspiron 1545 running an Intel Wifi 5100 AGN card

and no, i was not turning my router on and off in the log file.  that is what i was was referring to in my post about the signal drops.  that is what it does when the laptop tries to download emails and such.

It sounds like your router is having issues keeping a connection. It should not have any issues supporting multiple wireless connections using draft N technology.

My next suggestion would be to re-flash the firmware with the latest version from Linksys. Even if you  are running the latest version it dosent hurt to re-flash.

firmware reflash, signal drop problem persists

Have you tested with different draft N wireless computers or do you only have the one? Your old computers did they have draft N wifi adapters or were they using older B or G cards?

Also how much traffic are you putting on the router? Are the 3 or 4 computers all doing heavy internet usage (online gaming, Downloading, etc...). You could be overloading the router.

My thoughts right now are either:

a) you are overloading the router with traffic and it is locking up. (try disconnecting all computers except the new laptop and see if you can reproduce)

b) the wifi is having issues and causing the router to lock up. (disable wifi completely and connect all via cable and see if you can reproduce)

the old ones were B.  i do not have access to another draft n laptop.  it usually is triggered when the laptop does anything on the net...email, facebook, hulu... and has occured when the laptop was the only item using the net

Does the issue reproduce when the laptop is connected via cable?

having the laptop wired produces no signal drops...i tried to max out the net signal and couldn't ; playing online games on my pc, downloading content on my htpc, and watch streaming video on my laptop produced no signal drops...clearly this is a wireless issue

Im really starting to lean towards you having a bad router. Try these last few things:

1) follow the wifi settings in this post from the Linksys forums
http://forums.linksysbycisco.com/linksys/board/message?board.id=Wireless_Routers&message.id=127207&query.id=172220#M127207

2) If that does not help try dropping your wifi to G instead of N and see if that helps. Also make sure you are running the latest drivers on your wifi card.

the settings in the link you provided didn't help.  i purchased a d-link dir655 and i don't have anymore issues.

The solution was found. just because is was not the one you wanted it is still the correct solution and deserves points.

I posted at least twice suggesting the hardware was bad.

Linksys has said in an email that this particular router is having certain problems with a few n-draft wireless cards that will be fixed in an updated firmware once the 802.11n is adopted.  the router itself is fucntioning 'normally'  ...yeah right!~  normal as crap with n-draft
