We have a Netgear wireless network set up in my office. There are three computers on the Network. One is connected via USB directly to the router. One is connected with a Netgear wireless usb adaptor and there is a Laptop which connects via it's internal wireless adaptor.

Now, for some reason the Laptop loses connectivity sporadically and refuses to reconnect for a while. Magically, it seems to sort itself out after a period of time (sometimes up to 30 minutes later). Does anyone have any idea why this is happening? I am completely clueless where to look for a solution. It is causing immense irritation for my boss as he needs email access constantly. Any help would be greatly appreciated! 😞

its because computers are still crap and have a long way to go before they will do what we need them to do for us. dont believe the hype/ keep it simple for a quiet sane life.

I'm all for keeping it simple! I hate wrestling with computers, the less i rely on one the better, but this is work, we have deadlines to meet. We can't operate efficiently without a fully functional network, it's causing chaos and stress. πŸ™

Most internal wireless adaptors are pretty shoddy. What make and model does the laptop have?

As a short term solution, I'd suggest putting the Wireless receiver/router as high up as possible as they get better signals when they're above desk level.

It could be to do with placement. The laptop is going to be competing with the Netgear client for airspace. If the laptop is far away, or badly positioned with regard to the router the this could affect it.

It could also be interference from another wireless network in the vicinity. On the router you should be able to change the channel - either to a new fixed channel or there might be an option for the 'least congested'.

At work we have Cisco access points and these sometimes register a client and then 'lose' it. They then won't allow a connection from that same client for 30 minutes unless the access point is re-booted.
It registers the MAC address with the something, and keeps this for 30 minutes of inactivity before clearing the slot again - If the same MAC address comes in with a 'different' connection then it's rejected. Maybe a reboot of the NetGear would help you here?

On the netgear I have at home, I think there is an option for boosting the signal? Can't really remember, but it might be worth browsing the netgear config pages to see what can be set.

Hope this helps

netstumbler is an easy way to see what kind of wireless networks there are around, and to see if some channel is less congested.

Get your boss to spend a few £'s and get in someone who knows what they are doing to sort the problem.

Sometimes the simplest solutions are the best. πŸ˜›

Interesting, i'll try moving it. Incidently, we have wireless phones in the office and i have noticed the internet slows down when someone is on the phone. What sort of signal do phones use to be wireless around the office? Is it a radio signal? or is it the same sort of signal that our router sends out? Just wondering if the phone might be involved somehow...πŸ˜•

Excellent help!! Thank you, i'll play around with the channels, that's a great idea, thanks. πŸ˜€

We work on the principle that things go wrong all the time. If someone in the office is experienced at sorting them out then the problems go away quicker and with less cost. It's amazing how many ways it is possible to say 'cheap skate' in English, ain't it... πŸ˜€

Fantastic! It transpires that we were on the same channel as another local network that just so happened to be a Netgear router also! I've changed the channel and everything seems to be working. Let's just hope that was it. Thanks all for your help!! πŸ™‚

Also, if any of those wireless phones are 2.4ghz you will probably continue to have problems despite changing channels. The 2.4ghz phones will completely zap your wifi if they are anywhere near the router or the computer using the wireless.

Note: some of the newer network cards handle this better than older ones, but you still experience slowdowns while the phone is in use in the vicinity.

Overlap of channels is a big problem. There are 13 channels available for wireless networks, but they each overlap their neighbours. If you are on channel 1, then you'll be overlapping all the way to channel 5. The signal is more spread across a range of frequencies that limited to one.

Depending what protocol you are using, 802.1b/g/h etc you'll get very different throughputs - and this will also vary with the amount of clients sharing the channel and the amount each of them is using the bandwidth available.

A cheap hub / switch and a few metres of cat5 cable could solve your interference problems - and give you consistent high speed. Might be worth thinking about if you need to add any other clients to the network.
