Extracting username & password from 2504N?

[rhombus]

Has anyone got the details for the 2504N and successfully connected their own router to Sky?

Yes, I did it

(Think you got me mixed up with the original poster!)

Yes I did

He will be pleased to read that the method works

why would you want to extract it anyway its a n router isnt that good enough

From the reports so far it does not appear to be a full N router, it is what manufacturers call N Lite. There are other reasons for wanting a better router including gigabit lan, better parental controls, full QoS functions, a USB port and the ability to tweak the settings. You might not be interested in any of these, but many are.

[deadman1984]

you mean to say that this n router only does something like 150mb speed on wireless not 300mb like most do blyme

[Scubbie]

The BT HomeHub v2 & v3 only offer 130Mb.

I guess we should be happy that Sky has gone for the highest speed on the 20MHz bandwidth.

In order to benefit from these speeds, you do need an adaptor that can work with the speed. There are a lot of WiFi n adaptors out there which can only work with about half the advertised speed.

Gradually more are being introduced that will support the full WiFi n @ 300Mbps, but not many.

I want to extract the username & password because I have a Billion 7800N - this does full 300Mbps over wireless and has possibly the best Broadcom ADSL chipset around to date (BCM6358) as it incorporates Broadcom's impulse noise protection, this gives me at least 400kbps extra sync rate and on a line that only manages 3080kbps sync rate with it turned on, is a god send. It also has a great firewall and has EWAN support if my exchange ever gets VDSL!

My router has been shipped by Parcelforce so it should be here sometime this week, I'll let you all know how I get on. Thanks for the help guys.

The 2504N is 2-stream and therefore does not have the highest speed currently available with 20Mhz (which is 3-stream - the 802.11n spec allows for up to 4-stream).

2-stream adapters are commonplace, so if youre buying a new one, there's no reason not to opt for these.

Remember though, actual throughput bears no resemblance to the figures of '130' and '300' Mbps etc. You'll probably end up using your shiny new 300Mbps adapter in 20Mhz mode on 2.4Ghz, and get a peak maximum throughput of 70Mbps a short distance away (on the same desk, much less due to radio overloading!)

And be careful with Wireless N - in my real-world testing, all devices on the network need to be wireless N and preferably using at least 2-streams to get good performance. If you run any wireless G devices on your network, performance of the 2504N collapses for all devices on the network in Auto mode (just like most N routers) - and in the case of the 2504N even without using any bandwidth. And when using single-stream N devices, which is still the norm for smartphones and tablets, I get lacklustre performance and range to that device. In these scenarios, "54g performance" mode is far superior in my experience and opinion.

You'll forgive me for the apparent error. This figure I got from another site. I can't find it at the moment. It also happens to be the highest my own Netgear router can be set to when using the 20MHz bandwidth.

There is a new router available from Netgear now that has a maximum of 450mbps on one of the channel ranges. I'm not sure whether this is on the 2.4GHz or 5GHz channels though, nor how it is achieved. It only works to 300mbps on the other channel range.

2-stream adaptors are commonplace, so if you're buying a new one, there's no reason not to opt for these.

As you say, there are a whole range of WiFi n adaptors available now. There are a couple that will work with the full 450mbps speed too.

At the moment too few people appreciate that there is such differences. This means that if you purchase a Laptop that is WiFi n compliant, then it will not be until you get home that you will know what it's connection speed it likely to be.

Remember though, actual throughput bears no resemblance to the figures of '130' and '300' Bps etc. You'll probably end up using your shiny new 300Mbps adaptor in 20Mhz mode on 2.4Ghz, and get a peak maximum throughput of 70Mbps a short distance away (on the same desk, much less due to radio overloading!)

At this stage I can't answer that. The adaptors have been on order for a few weeks. One should have arrived at the UK supplier yesterday and should be with me this week.

The other was supposed to have been dispatched around the last Bank Holiday weekend and I haven't had any updates since.

And be careful with Wireless N - in my real-world testing, all devices on the network need to be wireless N and preferably using at least 2-streams to get good performance.

Ok I have the Sagem F@ST 2304n and a Netgear DGND3700. I can't comment on the Sagem Pack F@ST 2504N experience.

When I get the new adaptors I'll certainly see if there is any significant improvement in the performance. I also have a mobile that uses WiFi g, so I can mess things up if what you are saying is true with my router.

Of course! This thread was doomed for errors, what made you think Scubbie could escape it!

But yes, it can get confusing out there. If you look at the max Data Rates for 802.11n, it makes it all easier to understand.

No. Streams.....20 MHz / w. SGI........40 MHz / w. SGI

1..................................65 / 72.2 ..................135 / 150
2................................130 / 144.4.................270 / 300
3................................195 / 216.7.................405 / 450
4................................260 / 288.8.................540 / 600

(These can apply to 2.4GHz or 5GHz bands equally. For certification, 5GHz is optional, so is 40MHz, so is SGI/Short Guard Interval. Routers must have at least 2 streams, clients need just 1 stream)

So, from just the headline 'up to x Mbps' figure stamped all over a product, you can work out what's going on, or vice versa.

If there is no such Mbps figure with a product, such as a laptop, then anyone interested can easily find out what the internal wifi adapter is and look up the specs online or find a datasheet. If certified, then you can also look up the Wi-fi certificate and then tell the guaranteed data rates.

So for example, for the 2504N, you could tell its max rate would be 144 before setting hands on it because it was Wi-fi certified for 2 streams and for the Short Guard Interval option but not the 40MHz option.

Note however, that products can perform and be advertised with features and rates above their certification - it means however, that these didnt meet the full standards or pass interoperability tests. For example, your Netgear DGND3700 is advertised as 'up to 300Mbps', but it is not certified for the Short Guard Interval option, I think possibly (at least for one reason) because it does not have this option on the 20Mhz band which certified SGI products must have, so naturally it failed the interoperability test. Similarly, the 450Mbps Netgear WNDR4000, is only certified for 2 streams and therefore failed interoperability testing on its 3 stream performance.

Also on identification, wi-fi certified products can carry official certification logos (you've seen the ones I'm sure), and they have the option underneath to say 'dual-stream n', or 'multi-stream-n', or a matrix of number of streams for each band.

You can also see that it doesn't make sense to call 300Mbps or 450Mbps 'Full-n' and this isn't a term I've seen used before. In fact, Quantenna have trademarked "Full-11n" for use with their 4-stream devices.

Hope this helps.

PS I was speaking generally Scubbie, I didn't mean you in particular - I'm sure you know what youre doing and don't have to be careful at all! That you happen to have some shiny new 300Mbps things on their way to you was pure coincidence
