50M : Superhub is nowhere near as bad as people say!

[Kymmy]

Weird how this post came about when I'm just looking at designs for a 1.09Ghz collinear..

My worry with replacing a dipole for a collinear would be an impedance mismatch especially when running duplex on a single antenna, last thing you need is the transmit power to be feeding down the line to the receiver or causing oscillation further into the PCB.

Superhub has worked well for me up until Sunday. On Sunday the wireless connection suddenly became very unstable, dropping connection and offering extremely erratic speeds when it was connected. Wired connections were still 100% ok.

Seeing the classic signs of interference, and with people recently moved into the flat next door I assumed that they'd turned on a router to the same channel as mine and changed from 7 to 13. This fixed the problem until Monday. On Monday the connection speed remained normal but started to flat out stop working every 5 minutes or so, until the client (iPhone/laptop internal/PC external dongle) was disconnected then reconnected, but the problem would return a few minutes later.

This prompted me to change channel again (to 12), even though I could see through my PC's software that there weren't many competing networks and certainly none on CH13. This returned stability for the next hour or so until I went to bed.

Then this morning while browsing the net on my phone it returned, requiring me to turn off wifi and then back on in order to regain the connection. Faulty hardware, or what?

I have seen at least one report where a Superhub on auto apparently followed the frequency used by other Superhubs. It seems far fetched to me but so does a year waiting for a diagnosis and fix of a memory leak when there are supposedly half a million of the wretched things in operation.

As has been mentioned before there are only actually 3 non-overlapping channels in the 2.4GHz band - 1 6 and 11. Running on (say) 7 when there is another strong signal on 6 doesn't mean you will avoid all degradation.

Possibly next door are on Auto-channel or have one of these BT HH3s that bugger everyone else up at random.

All the BT hubs round here seem to be on ch10 so I normally manually put myself down in the lower ranges. Mind you I only bother with a G rated kindle and laptop on wifi as the whole house is wired for gigabit ethernet

This is why my network runs across channel 1, 5, 9, 13, 36, and 40.

can you confirm that Infinity comes with a modem so there's no need to use a HH at all please...

Loving the thread title.

The superhub is awful.

1 - To achieve 100 meg I need to be on 5ghz
2 - If i'm on 5ghz my iphones won't work on wifi
3 - The superhub doesn't support simultaneous 2.5 and 5ghz

....so....

Ditch the superhub for wifi - invest in an airport and.....

1 - Get 5 and 2.4 ghz
2 - Immediate wifi speed increase from 70 meg to 95 meg down.

Sorted.

The Superhub was costing be 25 meg down!!!!!

the rev03 for me seems improved on latency over the rev01 superhub.

Whilst I have no doubt you're having major issues with the shub, many people's works fine. I get a very solid 120mbps on mine without any dropouts. It's on 2.5ghz with a ton of people in our local area channel hopping daily.

Quick query, how did you go about getting access to ch 36 and 40? DD-WRT/OpenWRT?

Cheers

Any 5Ghz device should be able to do those channels by default.

[thenry]

5GHz is immense

[qasdfdsaq]

BFWA is immenser. Range wise that is.
