Pepwave Surf DHCP Clients not shown on client list

Please can somebody explain why I can’t see wired devices on the Client list when I know they are on the LAN and active.

I have various devices on my LAN that I can access across the LAN but for some reason they either aren’t on the client list or they show up from time-to-time.

I’m trying to sort out a problem with devices accessing the LAN via an AP and it would help if I could see the wired and wireless devices IP address that has been allocated by the router.

The problem is on both 7.1.0 and 7.1.0s021

I experienced something similar long ago. It may be that devices that only communicate on the LAN fall under the radar. That is, not using the Internet, limits them to the dumb switching hardware in the router rather than the higher routing processes.

Hello @Ptset,
If we are visiting a customers site and we want to diagnose there network, one of the tools we use is the freely available IP network scanning software from http://www.advanced-ip-scanner.com to build up a current client list, alternatively you can use a dedicated network analyser, good ones are expensive to acquire, though if you are doing this sort of work regularly, then the RoI may be worth it for you.

We have found with the Peplink equipment (as with all other brands too), the devices/clients on the router/gateway will drop off after a while if those devices are not regularly attempting to get outside network access even if the devices do have the gateway programmed into them. In house IoT equipment (such as Building management & AV systems) plus Restaurant POS systems we find regularly does not sit around in the client list on gateways & routers, so manually scanning the network is best way to check.

If you need to be constantly checking, then you are best to setup something like SolarWinds or PTRG, we prefer PTRG and you can get a free trial version from Discover the 3 Paessler PRTG monitoring solutions that will run easily on a low powered computer running on the network, both SolarWinds & PTRG are very feature packed, and you will need a bit of skill to set either up and get the most out of them.

Note: Some firewall software on computers will flag the above scanning techniques and block a response to the scan.

What you are experiencing is not a fault from our experience, it is just the routers/gatways working normally.

Thanks for your response and suggestions.

Although I have been in the networking industry since modems where high tech I’m not an engineer.

The problem is on my home network.

I’m trying to find out why there are long delays in devices getting access to the internet. Most devices time out waiting. The problem is most prevalent on wireless devices connecting via a separate AP.

Unfortunately the devices, iPad’s, media streamers etc., don’t have logging on them so at the moment its trail and error to get the problem fixed.

Peplink have tried to help by looking at the logs from the router. It looks like DHCP is issuing a IP address but it is getting lost/delayed somewhere maybe the AP or the end device. I’ve tried three different AP’s but the problem persists.

I do have a VLAN and the same AP’s attached to it work fine.

Looking on the web somebody experienced a similar problem created by unwanted VLAN tags on a Cisco network.

Its driving me nuts trying to fix this.

Thanks again

Peter

Hello @Ptset,
Can you post a simple sketch of how you have your network setup?

If you have a network switch in between your Pepwave Surf & the WAP, and if you are running VLANs, you need to have a switch that can handle VLANs. Most consumer switches are unable to do this and they will cause issues with VLAN tagged traffic.
If you do have a switch, you may find some of this other recent forum thread useful VLAN Setup on Managed Pepwaves - #5 by mldowling or it may open up more questions too.

Others here in the forum will look at this and if you have an image of your network it will assist them in guiding you.

Thanks Martin

I do have dumb Netgear switches in the network. I’ll check but I think the AP I’m having problems with is plugged directly into the router.

Thanks again

Hello @Ptset,
Are you able to plug the WAP directly into your Surf to test and help isolate the issue?

I think it is but ill check today.

Thanks for the help

I’ve plugged the AP directly into one of the router ports. Initially it was no better. I’ve now rebooted both the router and AP and internet connection is being made. I’ll test it later on. Rebooting in the past did initially fix the problem but then the problem reoccurred.

The client list on the Surf isn’t much help in that devices I know are attached and working OK don’t show up on the list including the AP’s. A Netgear utility I have on my PC can see all the devices I would expect to see.

Thanks again

Pete
