Lwip on my router?


Hi - I’m not technically savvy at all but I’ve noticed something called Lwip or Iwip on my network. I’ve tried googling and can’t fathom what it is or if it should be on the network.
it has ping
ive tried deleting it and it just re joins
it does change on the table to say it’s changed recently etc
it’s been doing my head in for mths
Is anything to worry about?
I’ve attached a pic below to show connected devices etc
any help would be greatly appreciated ??
cheers

Have you or anyone in your home recently installed any smart devices, such as a wifi plug, or lightbulb, etc.? Something like a smart wifi plug would be easy to overlook as connecting to your network, and if a member of your household installed one, would you necessarily be told since it's just a plug being used to remotely-control another device such as a lamp, coffee maker, etc. Just a thought. Please let us know what you find out, thank you!
Thank you so much for your response- Nothing at all like that tbh - only thing I can think is maybe wireless alarm ? But I don’t think it’s that as different make. I’ve googled the ip where it comes up with manufacturer - it says Azurewave technology - only thing I know of is my laptop has that on. Now I didn’t have my laptop on for ages and this thing keeps running and doing it’s thing so can’t see it being that either!? What does an Lwip do exactly do you know? Could it be transferring info from my phone ? I really am going round in circles with it tbh.
please help me get to the bottom of it. Cheers
Cheers sorry not seen other reply - its sc f5 I think - I’ve previously done this search amd it comes up Azurewave - now I know my laptop has this software or Whatever it is but I haven’t had my laptop on for ages and this thing is constantly changing status and running with ping etc - I got the MAC address off the router.
many info appreciated or if you need anything else - other than my bank details 🤣- let me know
cheers
Thanks I shall have a look now
Hello. This is a device whis has accessed your system because it has your access password. You said you tried deleting it and it keeps coming back and it will keep coming back because it has the current pw. If it bothers you just change your pw and then you will find the device that stopped working and you can re-add it and name it in fing. Yes I know it is a pain to change your pw but this will work! Good luck!!
I'd go with the process of elimination. Start turning things off, including the devices that already recognized and check for that IP going offline.
It might take some effort but it's really the only way to find something you can't otherwise identify.
I've had this before and after turning everything in the house off the device was still there.... Turned out I'd forgot about some baby room hub device that monitored temp and such... It never got actively used so I forgot it even existed until frantically racking my brain to discover some unknown device!
Good luck with the hunt!
Consumer grade will keep up with demand well enough. Problem with enterprise grade or even SMB is exactly that you'll need support for it. Businesses pay a lot for that support hence consumer grade is less complex and easier to support for general tech guys over the phone!
IoTs produce a lot of complexity but there are other boxes available that provide IoT security as some sort of Central wireless IoT hub that is consumer grade. That way you're largely back to a small consumer network with just one internet facing IoT hub and mainly Ethernet devices and maybe a few cellphones, laptops and tablets on the main network.
Solution has to be maintained by whoever builds it so may as well keep it simple!
Not gonna quote again as it's getting long winded...
When you say "true smart home", you're basically a very small minority in the grand scheme. Not many people need that level of tech and the ones that do are generally professional or trade so have at it.
Typical consumers couldn't manage that level of technology on a good day, on a bad day it's hours of debugging and tech support that frankly would crash the consumer IoT industry.
I can't debate how consumer tech would handle 100s of devices but not many people have that many. I've probably got less than 20 and I'm pretty much done. I don't need the kettle and fridge and door locks etc to be smart. Lights, TV, Alexa and heating is plenty enough for me and I imagine a fair amount of others too.
I doubt many people where I come from could even fit that much in their house... Not without 10 cameras in every room and every socket and switch having WiFi in it!
I found devices in my network I thought were possible hacker devices. Come to find out it is not safe to assume that not all my devices come with just one network required connections. Such like Alarm Systems, Ring Door Bell, Smart Devices, even your own Wifi System you put in place behind a Modem/Gateway might require additional network addresses equipped/provided with their own Mac addresses.
I would safely say, it would not be a wise choice to disable/block them. Without throughly verifying that not all of your devices require multiple throughput connections.
Use the fing app to help isolate the connection "Google" manufacturers of your devices connected, and verify that your device "Mac Address" line up/or are supported and built for your device manufacturers.
This will help to identify and label (rename), them accordingly. So when they fade away you can feel comfortable knowing what they are.
I found some of my devices turned themselves on at different times. After I had configured my network from DHCP to a Static Configuration. So once I had everything configured, and when a device that required a multiple throughput turned on or was active. It assumed an automatic address (DHCP configuration) , and presented itself to me. I was almost tempted to disable/block it, then I Googled the device manufacturer, and the mac address relationship. Supports one manufacturer to another manufacturer.
My advice is to "Google", especially before you are going to configure your network in a "Static" configuration. You just might want to allocate some addresses, for a "Lightweight IP's", that disappears the reappears on you.
I'm at 66 with around 30 running right now, I've got labs constantly spun up and down on a virtual machine server and various devices spread around the house. I guess I could hit 100 devices but I'm not worried about it. I'm not sure I've ever had 50+ devices actually demanding bandwidth; I've never had issues with the router. Personally I'd just rock on and look for answers for problems when they arise... if you actually intend to use more devices than your router will support then you're gonna need a better router, or multiple routers... but really at some point in you're squarely in SMB territory but IMO if you can manage that many devices you can probably manage an SMB router without too much hassle!
20 years ago I couldn't even imagine having 2 computers in the house... my biggest issue was trying to learn about networking without having access to one! What a time to be alive
And you base this assertion on what evidence exactly? Are you a smart home installer? If so you would know that a smart installer uses the appropriate technology for the specific conditions. Zwave, zigbee and IP based devices all have their strengths and weakness and to be fully integrated zwave and zigbee connected devices require an IP enabled controller or bridge. Further some classes of IoT devices are only IP based.
p.s. I didn't say they don't use Wi-Fi devices, but there are a lot more limitations and they're more susceptible to interference/hacking and generally are not as reliable in my experience. I have plenty of wi-fi based IoT devices on my home network, trust me, but for most of my clients I try and use Zwave Plus these days when I can.
I can't speak for what anyone else does but from my limited experience... My Yale smart alarm uses a central hub which I assume operates like zwave etc rather than WiFi and it's never failed once.
The Phillips hue range uses ZigBee, same story, never failed.
Alexa... Always falling offline for no reason. Generic WiFi smart bulbs, stop working randomly for no apparent reason or just delayed long enough to be annoying often enough to justify them being replaced by ZigBee etc... Smart panel heater in the office is so lousy at staying connected I had to pair it with a smart plug and python script to reset it on a cycle until it works just to get a reliably heated office at 6am every morning.
Smart phones never fail on the WiFi, and the ring devices seem to be pretty reliable so I'm sure it's the crappy WiFi chips on cheaper IoTs, but Amazon is rapidly becoming a marketplace for cheap rubbish knock offs it's getting hard to find anything reliably decent without a lot of research...
if that sounds like 'professional' to you , that is because it is - a typical smart home has as many network devices as many medium size businesses did 10 years go - and just as those businesses found out, throwing some network gear out there and making it work doesn't mean reliable and ready to do business.
