Wifi Router Antenna Extension Cable
« on: July 25, 2019, 06:30:57 am »
My neighbour shared his (uncapped) Wifi password with me, and I tend to use it later in the month when my LTE data is depleted. However my router does not pick the signal reliably to act as a wireless bridge/repeater. It is great at times, but it seems to waver up and down.

My Teclast tablet picks up his signal fine, not so my Dell Laptop or Samsung phone.

I was thinking of extending the antenna of the router to a more optimal position. What would be the best option on the cable? A 5m cable may get closer to him however the signal loss in the cable will be greater. A 1m cable may make a difference, I was wondering if daisy chaining another (1 or 2) 1m extension cable would be more optimal than a single 5m.

Any thoughts? A Yagi may be better option overall, still would like to hear thoughts on 2x1m vs a single 5m.

Move the router closer. Or better yet, get a second router that supports DD-WRT and use it in client mode.

I have several installations like that. A WIFI client which can be an Ethernet client or USB client or whatever, then some meters of Ethernet and then the main LAN router so my LAN is not on the same LAN as the neighbor.

Mainly I use stuff that I have lying around and avoid buying specific stuff. Old routers are pretty much free and can do many functions.

If he is really willing to share, work out a deal to split his internet service cost.

Then run an underground ethernet cable between his router and yours.   ;D  ;D  ;D
A shallow (25cm deep) ditch would be plenty.

Wow. I would not dream of doing that and I am sure my neighbor would also refuse.

Running a cable across property boundaries is very much illegal here, even if it is a mere data cable.

My LTE package is sufficient for my browsing needs, it is just that family visits have depleted around 5GB in 50 minutes on a couple of occasions. Internet service costs was not the issue, although he is on uncapped ADSL that is not available to me, I am on 20GB LTE data package.

Perhaps a DIY cantenna or Yagi is in order. Maybe a throwaway ESP8266 could be risked outside and serve as a repeater.

Maybe I should have asked in the RF section, I was just looking at a gut answer, my feeling is that 5m cable would have more losses than 2x1m cables.

Consider some long range, high power WiFi cards. They are illegal due to excessive radiation, but they are common in rural areas or when used to steal WiFi.

This is EXACTLY what we are being ask!
How to connect to and use the neighbors internet service.
Whether it is a hard connection or a WIFI connection makes NO difference.
I only suggested splitting the cost and using a hard line.

His neighbor already agreed by giving him his password.

I agree that's not really relevant to the problem stated. Maybe there's already an arrangement to share costs, maybe the neighbor is just a good neighbor, maybe he offers the neighbor something other than money (e.g. care for the pets) as compensation, etc...

I would say that a repeater would probably be the best solution, and while dual radio repeaters are fairly common nowadays, a router in AP mode connected to another router in client mode allows physically positioning both in their optimum locations. Avoid the super cheap single radio repeaters since that would halve the bandwidth of the network, or more accurately double your traffic contribution to the network. With a dual radio repeater, set the AP side to a different channel and there won't be any interference. It would actually *reduce* the bandwidth impact on the first network (albeit unlikely to be noticed) since the repeater would have a better connection, allowing higher bitrates.

I have a couple routers tested, the reception is marginal and positioning the router optimally is extremely awkward already with the use of electrical extension cables weighing the router down against the window. I just wanted to get either a 5m or 2x1m cable to extend the router antenna away from the router but placed optimally at the window.

I do have a unopened high powered router that I will test next. Thanks, moving on I think.

A Ubiquiti Nanostation locoM2 can be had for less than $50 to bridge between your wired and his wireless network.  It uses passive PoE so placement is only limited by where you can route an Ethernet cable.

Just get a fairly cheap router that supports DD-WRT and has removable antennas. Build a nice high gain antenna for it (a "biquad" is one good start) and it will probably work well enough. If you're really dealing with hard conditions or just want to have some fun, find a discarded satellite dish and replace the LNB (save that for future experimentation!) with your Wifi antenna.

Yes, buy some really old pile of crap and put ancient firmware on it, then build a hokey antenna for it..

Or just buy something decent.

Not everyone has the budget for enterprise hardware or the desire to learn how to configure it. Also, enterprise networks are typically designed to serve a large number (dozens to thousands) of devices all asking for a little bandwidth all the time while home networks typically only have to serve a dozen or so devices with generally only a few, maybe just one, using a lot of bandwidth at a time. 40MHz in the 2.4GHz band does not make sense in a large office since running two 20MHz APs instead yields better overall bandwidth for the network, but at home in a sparse neighborhood, it can boost performance. Hence some enterprise hardware doesn't even have the option for 40MHz in the 2.4GHz band, something I found out configuring an older Cisco AP for use at a family member's home.

Whether to use OpenWRT or DD-WRT is debatable, best to get hardware that supports both so you can try them out and go with whichever one you find better.

Get a high gain Yagi and find a good spot to mount it.
https://www.banggood.com/Yagi-2_4GHz-25dbi-WiFi-RP-SMA-Antenna-For-Wireless-Router-Outdoor-p-84566.html?rmmds=buy&cur_warehouse=CN
Yep, that has been in my cart. The good spot to mount it was the whole reason for this thread, that comes with 1.5m of cable and maybe another 1m would be perfect. I think I will trust the gain to overcome the losses due to the extension and extra length.

Coincidentally I already have an unused (9 years, sheesh!) dish mounted on the wall facing my neighbour.

I do not know if you can still find them but mounts to hold a Ubiquiti Nanostation Loco at the focus of those satellite dishes used to be available.  Later Ubiquiti released various low cost dish antennas with the WiFi AP built in.

my former brother in law "shared" his neighbor's internet connection for about five years. He was an OR nurse and was rarely home, so the $200/mo expense wasn't justified in his mind. Instead he slapped the neighbor $50-$75/mo and piggybacked off his. This was way back before the days of internet-enabled cell phones. He used a manual lawn edger to create a shallow trench into which he ran about a 50-75' run of cat-3 cable (I supplied) which he tied into his neighbor's router, and bought a cheap 10mb switch for his house. AFAIK the cable was still there when he sold the place 5 years later and moved to south carolina. I doubt the cable company was ever wise to it, since the cable was buried, and in the neighbor's house it just looked like another cat-3 run from "somewhere" to the router.

I know quite a few people with this kind of arrangement, including myself. Telecomms are not interested in selling you basic internet access for $15 /mo. They want to sell you a package with phone, TV, and a ton of things you do not need for "only" 86.60 plus tax plus pay per view plus a few more charges.

Wifi works well in the sense that the primary user always has priority because the secondary user is further away.

I have had good luck with RTL USB adapters (clients). In some cases I would add a reflector. 

I have my separate LAN which gateways into the neighbor's LAN. I don't want to be sharing my LAN with the neighbor.

Instead of a physical cable it uses small dishes, but it's basically the same thing.  You can also remove it to use it elsewhere if you like.

A small WiFi panel antenna might do the job. And don't forget the coax cable's attenuation (short = better).

A brief digression if I may. I have noticed you use code tags when you don't want the youtube video to show. Often I also want to provide just the link to the video but not have it show and play in the post. The workaround that I found is to add a time to the video link and that way it won't parse.

I've used this style with good success: https://www.banggood.com/custlink/KGmK8HpTqF

The Yagi is also a good solution.

Personally I'd run a fibre if they are literally next door. If not, I'd at least run the dish or Yagi at their end too.

I have a similar request really: all my desktop computers ae rack mounted, so, inside a metal box known as a server rack, and I need Bluetooth. If the cable run is short, for example in my case which the signal just need to be brought out of the metal box, you can use coax if your wireless hardware allows it. Usually it means a stretch of SMA cable. There are also cables that has a magnetic antenna stand on one end.

If the cable is a bit too long, you can use a Raspberry Pi 3 or above as the wireless to Ethernet adapter. Raspberry Pi 3 needs some form of 5V local power which can be derived from a solar panel and local batteries. Pi 3+ and above allows PoE which allows power be sent over to the Pi using the Ethernet cable. Alternatively there are also a lot of Mediatek MT7688 based modules out there. That is a wireless router chipset ad Mediatek released all of its documentations and drivers, allowing fantastic LEDE support.

On the topic regarding hard cabling t your neighbor's, fibre optics can be treated differently than Ethernet cables in building codes as those are often constructed entirely out of non-metallic materials, thus non-conductive. (Example: in the building code in Shanghai, Ethernet cables are not allowed to share conduit with mains wiring, but fibre optics can.) If your neighbor and the local regulation allows it, you can run a pair multimode fiber between the premises.

Good thinking. I had not thought of that aspect. On the one hand it might allow tracking the user/clicker. On the other hand it may be a good thing for the forum if it gives it exposure.

But, yes, most of the time I prefer to post just the link and let the reader decide if they want to go to YouTube to see it.

My machines uses internal Wi-Fi and Bluetooth mPCIe combo modules, so USB cables are not a solution. I need Bluetooth for my mouse and keyboard, and for my main workstation that is a Hackintosh various Apple specialty features that allows integration with my iPhone and iPad.
