Andy Kalita :

Hi, I can help you with this. You mentioned that it keeps resetting your router... Is that correct? Or do you mean that it drops the connection and then you have to reconnect?

Andy Kalita :

also, does it drop the connection after laptop has been sitting idle for a while, or even while you're actively working on the laptop?

Customer :

When I turned on the computer in the office this morning. The internet connection for everyone in our small office was disconnected including mine. After a few minutes the internet connection became available. Then within minutes after my computer reconnected the office internet connection again was disconnected. Only when I kept my computer powered off was everybody else able to work. This led me to conclude that the router was being affected.

The disconnection occurs even while I'm actively using my laptop. I'm using a wired connection currently. The only diagnostic message from the Lenovo utilities was that a driver for the office Network drive was not installed. I used device manager to disable the network drive. Not sure if that has an affect because I noticed things became flaky at my home office before I got to work.

It has degraded to the point that I cannot connect wirelessly at all.

Andy Kalita :

Ok, thanks for that info. What is the brand/model of the wireless router?

Customer :

The router is...

Customer :

Verizon-supplied actiontec MI424-wr

Customer :

but I was also having trouble at home with my linksys

Andy Kalita :

ok, give me a couple of minutes to get more info on this router

Andy Kalita :

well, since there is more than one computer experiencing this issue, I would first look at the router, so let me get some info on actiontec first

Customer :

sure. makes sense.

Customer :

Not sure if that's a router or a WAP. There's box in the closet.

Customer :

I think its a router. has RJ45 connectors

Andy Kalita :

It is a router

Andy Kalita :

ok from the computer that's connected to this router, please try the following

Andy Kalita :

open new Internet Explorer window

Andy Kalita :

into the address field, type 192168.1.1 and hit Enter

Andy Kalita :

you should be prompted for username/password. Enter the username/password XXXXX created during router setup

Customer :

Ok

Andy Kalita :

if it asks you to create username/password, then create whatever username/password XXXXX like, and make sure to write it down

Andy Kalita :

once in, click on Wireless Settings at the top of the page

Andy Kalita :

now, on the left, click on Basic Security Settings

Customer :

ok i'm logged on

Andy Kalita :

are you on Basic Security Settings screen?

Customer :

yes.

Andy Kalita :

ok, in Channel pull down box, what is currently selected? Is it Auto?

Customer :

yes. it is automatic

Andy Kalita :

click on it and select 11

Andy Kalita :

then, don't change anything else

Customer :

ok 11 selected

Andy Kalita :

Save settings/apply changes and exit the router configuration window

Customer :

we will be disconnected temp

Andy Kalita :

ok

Customer :

are you still there?

Andy Kalita :

yes

Andy Kalita :

so you saved settings?

Customer :

Ok. Settings have been saved.

Andy Kalita :

ok, try connecting to wireless again

Customer :

I'm still on wire.

Customer :

Ok. Let me switch profile

Andy Kalita :

ok

Customer :

wireless would not power on.

Customer :

Are we reconnected?

Andy Kalita :

yep

Andy Kalita :

so when you switched to wireless, what happened/

Customer :

Lenovo attempted to apply profile. It appeared from icon that laptop radio never powered on.

Andy Kalita :

can you try to toggle the wireless switch on the laptop off then back on?

Andy Kalita :

then try connecting to wireless again?

Customer :

ok

Customer :

On Lenovo there is Fn key

Customer :

should i unplug wire?

Andy Kalita :

you can leave wire plugged in, and after successfully applying wireless profile, you can disconnect the wire to test the connection

Customer :

now disconnected.

Customer :

unplugged

Customer :

are we still on?

Andy Kalita :

yes

Andy Kalita :

so you're on wireless now?

Customer :

Ok. Wireless for now.

Customer :

Wonder how long it will last?

Andy Kalita :

ok, how often or how soon did you get disconnected before?

Customer :

within a few minutes.

Andy Kalita :

ok, well you can test it as long as you'd like

Andy Kalita :

basically what we did on the router

Andy Kalita :

is set the channel that's preferred for data communications

Customer :

I'm looking for a setting for lenovo profile for channel 11

Andy Kalita :

default Auto setting is hunting for best channel, and it may set you to same channel as your cordless phone, etc

Andy Kalita :

you don't need to set channel on the laptop's wireless adapter

Customer :

Ok. Could cordless phone at home interfere?

Andy Kalita :

because if you set it to 11 and then take your laptop to location that has wireless channel set on auto, and it happens to be channel other than 11, you won't be able to connect

Andy Kalita :

yes

Andy Kalita :

so what i'd recommend you do at home, is this

Andy Kalita :

connect to your LInksys router

Andy Kalita :

open IE and navigate to 192.168.1.1

Andy Kalita :

when prompted, leave username blank and enter "admin" for password

Customer :

yup. know how

Andy Kalita :

once in, click on Wireless link at the top

Andy Kalita :

ok good

Customer :

yup and.?

Andy Kalita :

sorry, didn't get it

Customer :

After clicking on Wireless link at the top?

Andy Kalita :

oh, sorry

Andy Kalita :

then on the page below, click on Channel pull down box and set channel to 11

Andy Kalita :

save settings and you're good to go

Customer :

Ah. OK.

Customer :

OK. I accept your answers. thanks for help. Will colleagues have problem with new channel?

Andy Kalita :

shouldn't. All wireless adapters have channels set to auto by default, so unless someone changed it, they shouldn't have any issues

Customer :

In office building. Other companies have wireless. Can there be channel conflict?

Andy Kalita :

no

Andy Kalita :

since those are separate routers

Customer :

Ok. Can I increase your fee?

Andy Kalita :

After you click Accept, there will be option to leave bonus

Andy Kalita :

which is much appreciated, by the way

Customer :

Well, you deserve it.

Andy Kalita :

thanks

Customer :

It must have taken you time to learn.

Andy Kalita :

i've been in business since 1999

Customer :

Is there a way to request you for other problems?

Andy Kalita :

i'm pretty sure you'll have that option. If not, just mention it in the body of the question, and if I don't catch it, someone from other experts will refer it to me (or moderator will)

Customer :

thank you. bye now.

Andy Kalita :

bye
