content: I researched this all morning. Yuck. Bridges, adpaters, lions and tigers and bears oh my!I am setting up my home IP camera system and unfortunately I have Reolink Wi-Fi cameras that have crap connectivity. Even next to the router I get one or two bars.The problem is not the router or access points. So I want to use the LAN connector on the cameras to send/receive Wi-Fi.What device am I looking for and any suggestions on brands for those devices? And dumping the Reolinks is not a preferred option at this point. May come to it, but not there yet.THANKS!!

content: I used aVONETS VAR11N-300 WiFi Bridgeto connect a wired camera to wifi. Needs a bit of concentration when configuring but once set up worked well. Mostly - with BT Whole Home it would get steered onto the wrong access point for some reason and then throughput was pants. But ensure it connects to the right one and it's fine.Take no notice of the USB connector - it will take 12V up that cable via a DC plug, or 5V from USB.

content: TunnelVision (CVE-2024-3661): How Attackers Can Decloak Routing-Based VPNs For a Total VPN Leak (https://www.leviathansecurity.com/blog/tunnelvision).Long story short:Using DHCP option 121 (Classless Static Route Option, RFC 3442) the attacker installs static routes with a specific gateway on the target system. Traffic for those networks will be sent to the gateway and won't enter the VPN tunnel, i.e. that traffic is exposed. Network engineers would simply say: the more specifc route wins. This is neither new nor surprising. But it's good to make more people aware of this potential pitfall when connected to an unknown network and using a VPN.

content: Hello,I'm running into issues running out of endpoints on the xHCI USB hub controllers on my cards.I figured I'll just buy a new PCIe expansion card, but the marketing materials for these cards aren't helpful at determining how many endpoints each can support.I then thought that I'll find the USB Hub controller part that supports the most devices & endpoints, and then look for expansion cards built with that part.Even that is tough. I've got the data sheets for two parts but neither is clear about their available memory, nor the design limit on number of devices.Has anyone already gone to the effort of tabulating these parameters for a range of USB hub controller parts, and if so, would you be willing to share the winner?
Bluetooth 2.0 and 5.3 coexistence (bandwidth restriction?) - Page 1

content: I have wireless mouse and keyboard both using Bluetooth 2.0, and wireless headphones using Bluetooth 5.3. I have noticed that the audio quality on my computer is much worse than my phone. If I type very quickly just after I move the mouse, I might even get a dropout on the headphones.I am curious how much of this is BT 2.0's fault. It's a very old protocol and I assume it's going to take a lot more of the available data bandwidth than modern version under the same circumstances. I know for 802.11 (WiFi) this is the case. Is my assumption correct for Bluetooth?Thank you!

VLAN isolation and virtualisation. - Page 1

timestamp: September 08, 2023, 06:27:40 pm
content: Wow. Minefield.All my VLANs terminate at the LinksysWRT router. The PPP VLAN from the ISP, the LAN, GUEST, etc. etc. So obviously the firewall lives there too, all access switch if's are untagged 1 VLAN only and everyone lived happily ever after.I "upgraded" to a virtualisation environment host (VE) and recently added a "publicly accessible service" (PAS). Initial testing has been done with this PAS running in a container on a LAN subnet address on the VE host.I don't like this. While the main router is responsibly for firewalling the inbound traffic absolutely fine, the issue lies with the worst case of a red guy gaining shell on that container giving them unfirewalled access to the LAN... possibly.Firewalling between subnets/VLANs can be bypassed entirely by inter subnet, cross VLAN traffic accepted between bridges on the VE. Usually they are set up to forward between all possibly VLANs and networks, so you can create random environments. So it is also therefore essential you treat such hosts which "share" or "materialise" more than one VLAN into an IP stack are considered routers and/or firewalls.

content: Yea. So the mistake I made was to give the VE node an IP address on the DMZ VLAN.With that removed the VE node is invisible and nor can it route between the subnets/vlans.When I got to thinking. I believe a virtual pfSense might be handy as a single link point into/out of the DMZ and I can do the more complicated LAN<->DMZ rules in that rather than in OpenWRT.

content: Well that escalated rapidly. I now have a pfSense controlled DMZ. I am also being brave enough to add a further split horizon DNS so that pfSense can manage the DMZ hosts with it's own DHCP and DynDNS and leave mine alone.3 IFs. WAN, LAN, DMZ.WAN VLAN 66 direct from router with forwarded ports.LAN direct to LAN bridge.DMZ a fully virtual bridge.Technically I could just drop the LAN interface out and setup firewalling rules to allow the LAN in through the WAN side, but... I want to retain both access paths. I can test the WAN access by going through the default route to the DMZ, via the firewall, or I can add the direct route via the pfSense LAN gateway and get direct full open access.

Find correctly programmed OEM SFP for network switch - HPE Aruba J4858 - Page 1

timestamp: August 06, 2023, 01:23:51 pm
content: I need some input and opinions on the following topic:My boss has expressed the strong wish to move the office into a new building with different floor layout. This means, that the existing networking concept regarding access switches has to be modified.Long story short, I think of retiring some old access switches, move a handful of HP Procurve 2530 (now Aruba branded) switches from their current role as serverside switches to be the new access switches, and buy a pair of new and fancy 10 Gbit/s Switches as coe switches.So far so good, no problem doing this. As we will probably have to connect 3 networking cabinets on different floors, I want to use fiber optic cabling between them for several reasons.Up to this point, no problems, I consider myself fairly experienced in this regard.Where I would like to have some comments on/experience:In the past, with especially with new systems still under warranty, I advocated the idea of buying genuine materials from the manufacturer, to be sure that in case of support etc. no one can push the blame on "that other manufacturer"- Worked out so far, I might mention, especially in smaller networks.But due to the pricing of the SFP modules for the switches, that range about 150€ including sales tax, I really want to think about buying third-party SFP. As HP does not manufacture own SFP, some OEM probably will make them. What I am aware of, is that such a SFP sometimes has heavy programming inside- so not only an ID code an serial number for the management of the switch.In my case, we are talking about HPE J4858C oder Aruba J4858D (only difference the brand, otherwise supposed to be identical).Can anyone recommend a trustworthy brand (I remember Finisar as one of the more popular OEM) or share own experience in this regard?Also some links to further insight how the internal programming affect operations would be appreciated.

content: Hi, I have this old router which I would like to use as an access point. the thing is that this router was provided by the service provider many years ago. my problem is that when I try to enter the router in order to configure it, I'm getting a message that in order to protect from cyber hazards, I have to get an app that will allow me to enter. I don't want all the hassle and since it's a D-Link shelf product, I guess that there is a way to remove it and to bring it back to serve as a normally bought from store router. I found this article regarding it and since I'm no expert in networking - I will appreciate you opinion and help.The D-LINK 6850U is a VDSL modem + router given by Israeli telecom provider Bezeq to customers of their high-speed VDSL plans (so-called Next Generation Network - NGN). The device seems to be custom made by D-Link specifically for Bezeq, and it arrives flashed with custom Bezeq firmware that includes many “features” such as open-by-default remote management ports (with default usernames and passwords!) and remote “management” backdoors that are very hard to shut off.Note on TR-069 The modem/router has TR-069 enabled by default, the hidden URL to manage it is:http://10.0.0.138/_@tr69cfg.html(Where 10.0.0.138 is the default modem IP address). There is not explicit “disable” button there but changing the “ACS URL” (Bezeq server) to some internal IP address like 10.0.0.199 should do it.

Ubiquity sells complete units with dish reflectors just for this purpose and there are other competitors too (probably worth checking out). They might be overkill, depending on the distances.> any size piece of rural landThere are some pieces of rural land in Australia that warrant their own satellitesI recommend staying away from mesh networking at the wireless layer if you can avoid it, it's not a reliable as point-to-point links and whilstsome of it is standardisedI've also seen lots of nonstandard stuff advertised as "mesh" (requiring you to buy all the same equipment from the same vendor). If you want redundancy then I recommend you do redundant radios + links and then use some sort of routing mechanism (like spanning tree or whatever is better/easier these days) to auto-heal.

This is in a thick aluminium box which provides passive cooling, so I need to add an external antenna. I experimented with a flexible FPC antenna like this onehttps://www.mouser.de/datasheet/2/418/8/ENG_DS_2108792_B1-2065479.pdfwhich is meant to be mounted on a plastic enclosure. However, when stuck onto a ground plane it didn't work as desired.Is there any solution, apart from a traditional stick antenna? Or is there a way to get these FPC antennae to work on a metal box, for example with a suitable spacer? (Since the wavelength at 2.5 GHz is about 12cm and half that at 5GHz, I assume that it would need to be at least 1/4 wavelength away, so several cm minimum.)I'd be grateful for any advice.Cheers,Bruce

You can try searching for "puck" antennas if you want a finished product - not sure if you'll get one with an Ipex connector though, they normally come with SMA or SMA-RP so you'd need a pigtail unless you replace the cable (some are screwed together so you can do this easy enough)

You may have to read the manual on how to configure it correctly.

content: I should already know this, but I don't. I'm looking for a kind person who can explain this to me.My question concerns optical fiber connections. I know there is a 10GB fiber connection and it uses SFP+ in conjunction with 10GB network card and 10GB capable and SFP+ switches. I've done this and I understand this.Then there is a Fibre connection for storages. I've seen 4GB card and 8GB card. Questions at random order. Please note, I am not talking about iSCSI. I know these already.1) Can I mix and match and do they auto negotiate to the lowest common denominator?2) These cards are completely different animals to 10GB network cards, correct?3) SFP+ plugin module, are they same and interchangeable between network and storage?4) Do storage type Fiber connection go through switches or is it always one-to-one?5) Will you please post one or two link to these storage connection adapters on eBay?6) Is there a quick way to know the speed? How would one know without manuals, etc?Thank you very much.

Note that there is also the possibility of running fibre channel over ethernet (FCoE). There are converged storage adapters that provide both network and storage over the same physical Ethernet network.QuoteYes, both fibre channel and Ethernet use the same sfp modules. I think SDI video needs special SFPs that go to lower frequency.QuoteThere are fiber channel switches.

content: No. 6to4 is a mechanism for automatically provisioning tunneling of ipv6 over ipv4. This allows two remote ipv6 LANs to communicate even if they don't have a native ipv6 route between them. It's mostly obsolete now, as all backbones and most major ISPs support ipv6 natively.NAT64 can allow ipv6 only clients to communicate with ipv4 servers but there are a bunch of caveats, and it doesn't usually work the other way at all since an ipv4 client has no way to indicate an ipv6 destination. It's possible to create static NAT the other way: this would be the case if you had an ipv4 internet facing load balancer directing requests to ipv6 servers on your internal network, but it's a fixed mapping not general purpose like destination NAT / IP masquerading.

It's congested, slow and unreliable in RF-congested environments.If you are using 5 GHz, download something like the Ubiquiti WiFiman application on your phone to check for nearby networks and devices which might be interfering with yours. If your wireless router/access point isn't doing a good job of finding a free/less congested channel, you might need to force it over to something more suitable yourself.

content: You may have a two antenna diversity setup inside the laptop and one of them has become loose/disconnected.It's possible that when it downloads its just picking the antenna with the strongest received signal so you get good speeds. But when it transmits a lot of the power is being lost in the bad/disconnected antenna.This is just a guess, any RF graybeards feel free to correct me.Check out some disassembly video's for your laptop and see if it has two wifi antennas.(Note it may have a BT antenna too, so could have 3 or 2 where 1-2 is wifi and 1 is ble.So it can be a bit tricky to tell which is which unless you can identify which is the WIFI and BLE modules.)Alternatively you could also see if you can replace your WIFI module with a new one in case your one is bad. They usually don't cost much and are little plug in cards.

Shielded Twisted pair ethernet for WAP - Page 1

content: I ran into this at work, I had one theory to begin with but now have doubts. We have a training area that has a large cement block production machine/ line. They never put WIFI in there permanently thinking EMI, etc would make issues, but we have tried temporarily on occasion and i don't think was much issue. The way the building was set up though I got shielded twisted pair ethernet as it will likely run for 50-75 feet along the wall in this room to a wireless AP. I got a shielded/grounded patch panel for this for the rack side, the rack is tied to a ground plate in the IDF. My first thought was to ground only one end or it makes a ground loop, but then thought if I tapcon the WAP mount to brick then there is no ground for the WAP itself to the cable.I checked an I.T forum they say ground only one end but figured i'd try here too. Curious if anyone has info on this or dealt with things like this, hope this is the best location for this topic.

WiFi Monitor for Android with Single Channel METER - Page 1

content: I am trying to set up an optimized WiFi in my house, which is somewhat large and shaped like a U so there are extra internal/external walls between the two sides. My WiFi router is located at the rear at the top of one arm of the U. That is both my office and the closest point to the power pole where the optical fiber comes from. I can not change that without a lot of trouble and probably some expense that I would like to avoid.So I have purchased two Netgear, AC1900 mesh extenders and I need to find the best locations for them, hopefully one in each of the wings will be enough but I can always buy a third or fourth if needed. I had a WiFi monitoring app. in my previous Android cell phone which had a meter screen (round thing with numbers and a dial in the middle). That meter allowed me to walk around and measure the signal strength of a selected WiFi channel and I could select any of the channels that were in range. I can not remember the name of that app.Can anyone suggest an Android app. that will do this. I already have several loaded and working that have graph style displays, but they take some time to update unlike the meter which only took a second or two.

If you're talking about a fixed installation such as a desktop PC, a Yagi antenna or 'cantenna' pointed at your AP? Or just go wired which will not only save you heat/power but improve your throughput and give far lower latency.

If you can only place one where your computer is (and not at the other end where the Internet or main network is originating) you need to make sure you get a model that can connect to regular Wi-Fi as a client. Some of Ubiquiti's models will only communicate with their corresponding bridge and not general Wi-Fi access points.https://store.ui.com/collections/operator-airmax-devices
