Potential Wireless Issues

[davida1992]

Hi All!!!

So for a while now we have had a BT Business Hub in place which has been working OK without issues, dropping connection sometimes due to being on terrible ADSL in the middle of nowhere! 

I work offsite a lot and ideally need to remote in and manage certain aspects sometimes away from the office and therefore I was going to put a Draytek 2830n in to replace the BT Business Hub due to VLAN functionality, VPN etc built into the Draytek!.

After putting the Draytek in I was having some wireless related issues, cabled connections and internet connection are fine!!

I tried the Draytek at my own house and it appeared to work fine, i then took it back to where it will live and did some testing, this is the setup.

When the Draytek is configured it gets Sync, internet connection works over wired devices, DHCP is given from the server and everything is great!

However, when you try to connect a wireless device I have found a few different things happen:
I tried to connect a laptop and enter the password for Wifi it tries to connect me and fails, the wireless SSID then disappears for the laptop completely and I can only seem to get it back by restarting the Draytek.
The SSID still showed for my phone so i tried to connect that and it just kept coming up on the phone that the network was Saves but it would not connect at all.

Took back onsite tonight, same issue, didnt even plug it into the network, just a ethernet cable to my laptop, configured it with default SSID and a password and connected another laptop and my phone to it. Changed the Channels on the other 2 Wifi AP's to 1 and 12 and put the Draytek on 6. Used my other laptop to monitor any SSID's it could see, most of the time it was just the one from the Draytek, now and again the other AP's onsite would creep on but only at 1 bar because they are so far away. I have also tried turning off the other AP's to try and resolve the issue but it did not help, the place is in the middle of nowhere in a large house with only fields around it, so no other broadcasts.

I could connect my laptop and phone and it would eventually disconnect them and dissapear, although on the laptop showing the SSID's in range, the draytek would always remain and never dissapear, but the laptop and phone would usually disconnect and the AP would dissapear.

On the phone it would connect sometimes for some time, then it would disconnect, show on the phone as "Saved", and when i try to connect again it would come up connecting....and then change back to Saved....

I have tried to remove any sort of device that could interfere such as a bluetooth card machine, British Gas Wireless transmitter, 2 Way Radios etc and still the same thing happens! The BT hub is fine, if it is in the same place it works perfectly, just the Draytek, tried 2 different ones, same model, but just has this issue onsite... I am so stumped!!

I bet a lot of you are wondering at this point why I am putting something that is not a BT product on this forum??

Well, at the moment due to the issues the BT Business Hub is still being used for broadband and WiFi but I have just looked on the logs and found that things are doing a lot of disconnecting and reconnecting. I am wondering if this is normal? I am thinking that the same thing that is happening to the Draytek is actually happening with the BT hub, however the hub is better at dealing with it so the users are not actually seeing the issue, looking at the below logs from the router, does this appear to be normal behaviour?

Thanks muchly!!
