r/NepalSecondary Router or Mesh Wifi?
8 months ago

yoo same ISP and internet package and i got a Mesh WiFi as well. bought it off from India as the sellers here just rip you off on any networking devices. i got TP-Link Deco M4(INR 2599 = NPR 4155) via third party and paying the added customs + vat + delivery fees costed me around NPR 5200-5300 which is way cheaper than buying it here for NPR 8750-10000 each. if you are only planning on buying a single mesh router, i would advice to just get a normal router like TP-Link Archer WiFi6 instead and use it as AP mode. but if you plan on having multiple routers, get a mesh one with WiFi6.

Go for Mesh. If you are looking for more than 500Mbps connection you might need to connect the units using LAN cables. I used this one for my parents house. https://www.amazon.in/TP-Link-Deco-M4-AC1200-System/dp/B07KJ2TDMR/

Yeah needs to be plugged in. You take LAN out of your main router and connect to one of the units (base unit). Then the second unit can connect wirelessly to the base or via LAN cables. Something like this 1. Router ----- Deco Base )))))))) 2nd Unit 2. Router ----- Deco Base ------ 2nd Unit \--- LAN connection )))) WiFi backhaul Remember when using WiFi backhaul, the max speed of the second unit will depend on the strength of Base unit's Wifi signal where the 2nd unit is placed. My set up is like the router is upstairs computer room. Base unit directly connected to router via LAN cable. The 2nd unit is kept near the stairwell which covers all the downstairs. The range of the units are way better than the BSNL supplied ones.

I had a TP-Link Mesh system (Deco M4), not possible. Maybe on their routers.

r/HomeNetworkingWhat are the best gaming routers for around $100?

I used to have a TP-Link AC1200 router. I’m not sure if it was because I was torrenting for a longer period or more torrents, but the router would throttle to 1 Mbps. I’m not sure why this happened, but when I rebooted the router, it would work fine again. This happened a lot, but it happened less often with the ASUS router.

r/SpectrumWhat routers work well/are compatible with Spectrum WiFi?

Yeah, you'll have to get the new free modem that isn't a Wi-Fi/modem combo. Then you can buy a 30$ TP AC1200 router on Amazon and boom you save $10 a month. it's what I did, I told them I was switching to frontier for 29.99 and the agent lowered me to $50 a month with the wifi router, and told me to return the router when I got my own. I dragged my for two months but it paid for itself. I'm not techy but It was easy

r/HomeNetworkingWhich router should I get
2 months ago

I live in a 4600 square feet house. The modem aka the main router is downstairs and the download speed is 300 Mbps and upload speed is 100 Mbps. The router which is near my room upstairs gives me a speed of 30 Mbps the name of the router is tp link ac1200. What router do you recommend budget $300.

r/HomeNetworkingWhat is a rock-solid affordable router for an average family?
10 months ago

I can’t speak for the eero myself since it’s actually my brother who’s using it and I’ve got a Deco actually lol. The app kinda sucks but once it’s all setup I didn’t need to do anything else. Got the 3 pack from Costco and it’s been solid. Just needed to turn off fast roaming since it was cutting off uploads randomly. Guess the house is too small for 3 APs.

I have a 3000 sq ft home and tricked tplink 3 deco unitsand am disappointed with it. Numerous units drop connection and it doesn’t cover my entire house. My 5 yr old orbi system never had these issues
