FAQ
TL;DR: 2.4 GHz throughput can plunge from 120 Mb/s to 5-10 Mb/s in crowded blocks [Elektroda, 19siwy20, post #17457028] “This TP Link has wifi only at 2.4 GHz” [Elektroda, KOCUREK1970, post #17458227] Bridge mode plus a dual-band gigabit router restores full speed and open ports.
Why it matters: Picking the right mode and hardware prevents 90 % of speed-loss complaints.
Quick Facts
• Vectra package tested: 150 Mb/s down / 145 Mb/s cable reality [Elektroda, 19siwy20, post #17457028]
• TL-WR1043ND: single-band 2.4 GHz, N300, Gigabit WAN/LAN [TP-Link Spec, 2023].
• Technicolor CGA2121: DOCSIS 3.0 24×8, dual-band AC1200 [Technicolor Datasheet, 2022].
• Entry-level dual-band gigabit routers: ≈300 PLN (≈65 USD) [Elektroda, KOCUREK1970, post #17458753]
• Bridge mode hands out ONE public IPv4; extra devices need a router [Elektroda, KOCUREK1970, post #17692014]
Why does my TL-WR1043ND deliver only 5–10 Mb/s over WiFi?
The router works solely on congested 2.4 GHz. Neighbours share the same 13 channels, so effective speed drops to 5–10 Mb/s even though cable hits 150 Mb/s
[Elektroda, 19siwy20, post #17457028]
Does the TL-WR1043ND support 5 GHz?
How can I check if the Technicolor CGA2121 is really in bridge mode?
Will WiFi on the CGA2121 turn off after enabling bridge?
Can I keep my custom DNS when switching to bridge?
What affordable router should I buy to exploit 150 Mb/s and 5 GHz?
Why are my torrents green on the TP-Link but red on the ISP modem?
Is it possible to hit 100 Mb/s on 2.4 GHz?
Only in ideal conditions. Average real-world 2.4 GHz tops at ~60 Mb/s due to protocol overhead [SmallNetBuilder, 2021].
Edge-case: my UniFi AP allows only one WiFi client when connected to a bridged CGA2121—why?
How do I put the CGA2121 into bridge mode?
