If you really want to see what else is out there, including hidden networks, drop back into Ubuntu and install Kismet.

FunkyCable,

I would suggest either borrowing a router from someone and testing or if you're feeling a little ca$h rich go out and get a new one.

How old is the router? The latest firmware is 28/10/05 (version #197e7b)

The only thing I can find on the FAQ from Safecom that relates to SWBR-5400 and telewest (10Meg) is:

http://adsltech.com/portal/forum/for...?TID=6597&PN=6

Speeds fine through wired and slow on wireless (1.5Mpbs, All be it through wireless B connection). The safecom admin repling says it's a problem with wireless B talking to G. From reading the specifications the router is backwards compatible :shrug:. OK you're never going to get 11Mbps which is the max. for wireless B standard, but I would have thought it would have been higher than 1-1.5Mbps.

:idea:This might sound daft but:
On 10Meg connection the router speed is fine wired, but to Wireless B max. 11Mbps and only getting 1.5Mbps (aprrox. 13.64%)
On 20Meg connection the router speed is fine wired,but to Wireless G max. 54Mbps and only getting 7Mbps ( approx. 12.96%)

It does sound daft, but the two percentage figures are too close to be daft.

Before spending the money, just rerun your tests on the non overlapping channels 1, 6 and 11.

It could be another AP interfering or something else entirely.

Noggo, thats the version I have on my Router.

The strange thing is whe nI was on 2MB I got 2mb connection via wireless.

I'll try that test that Aragon an Geoff mention this weekend and post back my results.

thanks to everybody so far for the assistance that I've received I really appreciate it.

Re: time for an upgrade?
 
Yep but you're using wireless g standard both at router and on laptop. Where as the person who posted on asdltech.com forum is G for router and B for laptop. I was pointing out that it was uncanny that both throughput percentages on B and G standards are near enough the same (approx. 13%) on your model of router, so it's the wireless capability of the router letting you down with a maximum throughput of around 7Mb regardless of what internet connection speed you're got.

So on 2Mb connection you're not going to see any problems, as the max throughput of the router wirelessly is 7Mb. The problem only becomes apparent when you're either got a higher speed internet connection than 7Mb or you transfer files from one network PC to another other using wireless.

Aragon can you help me with installing Kismet?

I have ubuntu 8.10. I tried to follow this http://mihirknows.blogspot.com/2008/...buntu-810.html but when I run sudo kismet it displays this

Code:
sudo kismet
Launching kismet_server: //usr/bin/kismet_server
Suid priv-dropping disabled.  This may not be secure.
No specific sources given to be enabled, all will be enabled.
Non-RFMon VAPs will be destroyed on multi-vap interfaces (ie, madwifi-ng)
Enabling channel hopping.
Enabling channel splitting.
NOTICE: Disabling channel hopping, no enabled sources are able to change channel.
Source 0 (wifi): Enabling monitor mode for zd1211 source interface eth0 channel 6...
FATAL: mode get ioctl failed 95:Operation not supported
Done.
I edited the config file and uncommented the suiduser line to and entered in my username I use to login to ubuntu I then changed the source to the following source=zd1211,eth0,wifi

Have a look through this old Ubuntu forum thread - it might help. Or this guide. Otherwise - pass!

Have you found out why the adapter won't connect to the router once you change with router channel? Changing and then testing other channels will be the best option, if you can't borrow a another router to test or get netstumbler / Kismet to run. Just run through all available channels and then choose the one with the best speed.

Re: time for an upgrade?
 
Just tried Kismet running under BackTrack and it worked first time with my laptop. Also told me there are two other networks on my channel plus two in range on different channels (one unsecured and one using WEP!). You can't get it running on Ubuntu, try downloading either the ISO or USB install for BT3.

Hi Noggo

I log into the router and change the wireless channel I then reboot the router repair the connection but it will not connect. Any ideas?

Today when running netstumbler I saw two other networks. So I am stil on channel 11. The other netowrk that I knew about is on channel 1 and I noticed two other networks on channel 11. I just hope I can get it to work without having to buy another router.

Aragon I could not get kismet to work.

I've no idea why you can't pick up the connection after you change the wireless channel. What wireless adapter card have you got, may be they have support pages or forum which would shed some light onto why.

But by the looks of it with two other local networks on 11, you're got to try and move it.

Re: time for an upgrade?
 
Strangely I got channel 1 working. I changed it to channel1 restarted the router. Tried to repair connection and it would not connect so I plugged the wire in so that I could connect to router and chnage the channel back and when I connected the cable the wireless seemed to connect to the router. I did some speed again I got below 10mb but it was a little improvement. There is another network on channel 1.

I tried channel 6 but it would not connect even with the wire plugged in like I managed to get channel 1 to work.

With the cable only plugged in

On channel 1 with wireless only connected.

Re: time for an upgrade?
 
OK it's an improvement but 8Meg still isn't right. Try with other channels if you can get them to work or is there anyone you can borrow a more up to date router from to test?

I think what Popper mention over in your other thread post 13 applies http://www.cableforum.co.uk/board/12...eck-speed.html

Re: time for an upgrade?
 
Unfortunately all my mates are on ASDL and the ones that are on CABLE dont have wireless routers.

I think I will just have to get a new router and possibly adaptor.

I was thinking of getting a D-LINK DKT400 N router with usb adaptor but I wanted to get soem views on it here http://www.cableforum.co.uk/board/87...-any-good.html

I cant find any reviews for this product though so not sure if its worth the £46.
