Cisco 887VAW

[Luke Fahey]

Hey Guys

I have just setup my new cisco 887 wireless embeded router. I'm finding clients have very poor wireless signal strength. All client machines support G only. Do i have a mistake in my config or do these routers have very poor wireless.

Any help appreciated.

Hi Luke,

You made a site survey?

What is the distance between the poorly connected clients and the AP?

Try applying this command under the radio interface:

channel least-congested

This will choose best available channel to use. If the problem persists then you better check your RF noise and/or interference.

Don't. Just rate the useful answers,
that is more useful than "Thank you".

Thanks for the info, I will give this a try. I have not completed a survey but have no interfernece on the channel selected. The issue i have is this router replaced a standard linksys home grade router. I have had to reinstall the linksys as it provided better coverage with the exact same channel, encryption etc.

The distance is about 10 metres but through a few solid walls. The ap works fine when you are in the same room. But when in the distant room it connects at 54mb then drops back to 36mbps then seems to just start dropping packets while still reporting as being connected.

Luke,

I just replaced on of these. Our end user had this deployed in their home and they somewhat worked while in the same room as the router but once leaving the room their ping times (to the router) went from 30ms to 1500+ ms.

At that time I was also running Cisco spectrum expert and there didn't seem to be any interference I could see. However I am fairly new to all of this.

I ended up opening a TAC case and they shipped a replacement router. I put it in place with the exact same config and haven't had any issues since.

So if you find no wireless problems you could try replacing the router with a known working one if you have one.

Regards,

Aaron
