0बीटी मेष वाईफ़ाई

एक pfSense रूटर के साथ मेरे बीटी SmartHub बदलने के बाद, मैं भी घर वाईफ़ाई उन्नयन करने के लिए देख रहा है. जब वायरलेस मुश्किल से एक वास्तविकता था अधिकांश उपकरणों तार कर रहे हैं के रूप में सबसे कमरे कनेक्शन मैं साल पहले अपने माता पिता के लिए फिट तार है. हालांकि फोन, गोलियाँ, e‑readers, और लैपटॉप वास्तव में वायरलेस के साथ सबसे अच्छा काम करते हो (या केवल कुछ मामलों में वायरलेस के साथ), and to work well need a wire­less sys­tem that enables mobility.

Our house is old and fairly large — no single wire­less point has ever provided reli­able cov­er­age, so I pre­vi­ously had 2 net­gear EX6150 access points to ensure full cov­er­age. मैं भी था 1 PC linked via power­line adaptors which I have been very unim­pressed with. I had looked at wire­less mesh net­works and reviews a few times but felt (और अब भी लगता है) that £100-£200 per access point is day­light rob­bery. There are plenty of basic devices out there for £50 or less than have all the hard­ware required, so I decided to invest­ig­ate if these cheap devices could be turned into a mesh network

I should be clear about the dif­fer­ence between a mesh net­work and a col­lec­tion of access points, as many oth­er art­icles are not clear on this point. The key dif­fer­ence with a mesh net­work is that the access points com­mu­nic­ate with each oth­er and then tell cli­ent devices which access point to com­mu­nic­ate with. With a set of nor­mal access points a cli­ent device will stay con­nec­ted as long as it can and will only switch to a new access point if it loses con­nec­tion to the ori­gin­al. This means you can have a very low speed sig­nal from a dis­tance access point depite being near to a much stronger sig­nal from a dif­fer­ent access point. To put it simply — if you want to be able to roam and always get the best pos­sible con­nec­tion you need a mesh network.

To turn a cheap device into a mesh-com­pat­ible device just means the soft­ware on it needs to be able to com­mu­nic­ate with the oth­er access points and then issue advice to cli­ents about the best access point to use. Of course no-one if giv­ing away free soft­ware upgrades to old or cheap devices — instead they’d rather you junk the old hard­ware and splash out on new. For­tu­nately there are sev­er­al open source replace­ments avail­able, Open­WRT, सदस्यों, डीडी-WRT, और टमाटर जो कई वर्ष रूटर और पहुंच बिंदुओं पर दिखाया जा सकता है.

Unfor­tu­nately for me, none of the open source builds appeared to be com­pat­ible with either my BT SmartHub (v6) or the Net­gear EX6150 access points, prob­ably because they’re यूके केवल उपकरणों. I con­sidered buy­ing 2 या 3 cheap routers to flash and had a look around for sales on any routers with wire­less-ac sup­port. The only mod­els under £50 were TP-Link devices which were also not lis­ted as sup­por­ted by any of the open source builds.

I had resolved to wait for devices to come down in price but then spot­ted that the BT Whole Home WiFi sys­tem was on offer with 2 डिस्क केवल £ 100. After a little research I ascer­tained that all devices fea­tured a wired eth­er­net port, that the sys­tem sup­ports wired eth­er­net “back­haul” and that 2 sets would work togeth­er as a single big set. मैंनें आदेश दिया 2 किट, इसलिए केवल £ 200 के लिए मुझे मिल गया 4 अभिगम बिंदु.

Ini­tial impres­sions (केवल एक सप्ताह के बाद) are very pos­it­ive. Set­ting up the sys­tem was straight-for­ward — con­nect each device in turn via a wired con­nec­tion so that it can receive the set­tings for the sys­tem across the wired net­work, तो अनप्लग, loc­ate it where you need (with­in range of anoth­er access point) और दूर तुम जाओ. I con­nec­ted all of my devices to wired con­nec­tions and left them there. I now get multi-hun­dred mega­bit wire­less con­nec­tions in every room in the house, and when mov­ing between rooms han­dover works fant­ast­ic­ally and seam­lessly. For the price I’m very impressed with the sys­tem so far.
