Wireless signal issues with my Sonicpoints  (Sonicwall)

I have a Sonicwall TZ200W with two sonicpoints (APs) attached to it, however the signal continues to drop and devices get disconnected from the sonicpoints suddenly. The sonicpoints work for a while and then users report their devices are slow accessing the network, or they lost connection however they can reconnect and use the network.

I have two SSIDs broadcasting (one private and one public). I have a maximum of 35 devices connecting to the public network and unlimited to the private network.

I have 4 mobile devices using Windows embedded and also have three devices using Windows 8.1 connecting to the private network. These devices work for a few minutes and as users are scanning items on the shelves then the devices disconnect and we are having to reconnect constantly, however this issue is not consistent, there are days that everything goes very  well and there are other days that we have more issues than others when using the wireless network.

Thank you in advance for any help with this issue.

Just to ask the obvious - you have updated to the latest code release.  I have two SonicWalls running without issue, however, I know they are fully updated.

The other areas to check are your license provisions and the overall processor demands on the SonicWall.  I assume the SonicWall is acting as your DHCP server - do you have sufficient address space - is there potential for duplicate IP addresses?

Look at the logs and they should give you a good idea as to where your problem lies.

Thank you!

The private and the public SSIDs are on different subnets than the rest of the network and I don't know if this will cause the DHCP to run out of IPs.

I am not sure if there are other settings that might affect the clients connection to the wireless, i.e intrusion prevention, or other?

I had a similar issue - had to adjust channels as i had a neighbor battling for channel space.

Look for competing AP's in your vicinity.

You can block these AP's in sonicwall

Have you scanned for other networks in the area? If you need a suggestion on apps that you can use for this, many exist, I just happen to use Wifi Explorer on my Android phone. Chances are you have interference issues.

I'm not sure what type of area the office is located in, but if you are in an area like the downtown of a city, I would recommend that you look into Sonicpoints that support 5 GHz (hopefully you also devices that support 5 GHz). You may also find that you have to adjust the transmit power on each Sonicpoint to get an optimal result.

Yes, I can see that the sonicpoints are scanning about 5 more APs round our buildings. How can I stop the sonicpoints to scan for these APs, or is there a way we can block them completely from appearing?

Thanks,

I am still looking at this and haven't had a chance to look at the suggested solution. I will be posting soon the results.

Thanks,
