Re: HH3 Connections....

Yeah done all that when I rang BT the other day they told me to switch HH3 and Modem off and change to the B/G/N from just N to recommended which I have done but makes no difference I've got a wifi scanner so that's why I went onto Channel 4 as some ppl round me are on them Channels.

Re: HH3 Connections....

Check which channels are used the most and keep clear of it/them, but bear in mind wifi overlap

 

That's why 'smart wifi' only uses channel 1 or 6 or 11;)

Re: HH3 Connections....

BT Broadband engineer has just come about an hour ago changed my HH3 (TypeA) for a new (TypeB) and look no problems now with the Wifi dropping out so far.

Re: HH3 Connections....

It may still be worth referring to the image I posted above.

Re: HH3 Connections....

@sparky and @mcgrath

 

you guys need to do some reading which i think will help you undersatnd how wireless deals with interfence and channel overlap

 

picking 10 or 4 can be worse than picking 1, 6, 11 with minimal people on

 

as others might see it as noise and both of u will suffer where as if u are on same channel then the

 

Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) mechanism built into the protocol coordinates their communication. This access method - similar to CSMA/CDused in wired Ethernet - makes sure that only one product transmits at a time, so that the data is understood by all receivers.

But when the radio energy detected by a piece of WLAN gear can't be understood - even if that energy comes from valid WLAN equipment - it turns into noise. Wireless LAN gear does a remarkable job of differentiating between signal and noise, but not all products are created equal in this area.

 

also 40hz is v neighbour unfriendly if u are near to your neighbours and ther are alot of them thought it is supposed to rdrop back to 20 if it sees other deivces

for your reading

Re: HH3 Connections....

@spar I do understand how wireless works thanks Smiley Wink I've had Infinity over 12months now and it's only in the last 2weeks that the HH3 type A has become faulty. I've had a BT Broadband engineer come out 2day he was here for 1hr looking at the problem which he said it was a fault with the HH3 typeA which he replaced it with a typeB and for 9hrs or so now I've had no problems at all "SO FINGERS CROSSED"

Re: HH3 Connections....

ah kewl mcgrath im glad the type b sorted the issue but the fact u picked channel 4 left me thinking do you know how wifi deals with overlapping channels?

 

as in your previous post u said u picked channel 4

 

do u think this is good or bad based on the articles i linked too?

 

there is an argument that 4 channels can be used with negliable interfernce 1 5 9 13

 

but it requires all neighbours to do the same and be neighbour friendly so picking 4 is not good

 

also by using 40z u crowd the bandwidth even more, but the routers are supposed to be have friendly and drop back to 20hz if they see other devices.

 

same goes for sparky

 

Currently on channel 10 as there are a few others using the lower channels close to me....

 

this is also bad according to the articles

 

having said all that if neighbours are far enough away with weak signals u prob wont make a diff and depends on what other devices are adding noise eg babymonitors

 

i just want people to fully understand how just picking channels randomly isnt necessarily a good thing

 

esp in flats, i see people on 8 9 4 e etc  they dont realise this can actually be worse.

 

i will add i dont know if they have improved the tech since i last had to know all about this with beam forming etc
