        "content": "If you\u2019re not getting the gigabit speeds you expect with your setup (Virgin Media Hub 5 + TP-Link BE25 in modem/bridge mode), there are several places where things can bottleneck. Let's go through what to check and how to maximize performance.\n\n---\n\n## What to Know: Hub 5 vs Hub 5x\n\nFirst, it\u2019s super important to make sure which hub you actually have, because their capabilities differ:\n\n- **Hub 5** (DOCSIS cable to your home): Does support *modem mode*. You can switch off its router features and use a separate router. ([comparebroadband.org.uk](https://www.comparebroadband.org.uk/virgin-media/virgin-media-hub-5-5x-explained-review-guide/?utm_source=openai))  \n- **Hub 5x** (full-fibre/XGS-PON): At the moment, widely does **not** support stable modem mode. It\u2019s technically being worked on, but the feature isn't reliable or fully rolled out. ([ispreview.co.uk](https://www.ispreview.co.uk/index.php/2024/04/update-on-the-state-of-modem-mode-for-virgin-medias-hub-5x.html?utm_source=openai))  \n\nIf you have the 5x, you might think you\u2019re in modem mode, but that might not be letting everything pass through as expected, which could explain the speed issues.\n\n---\n\n## Possible Bottlenecks & What to Check\n\nTo figure out what\u2019s holding you back, look at these common trouble spots:\n\n| Component | What to Check | Why It Matters |\n|----------|------------------|----------------|\n| **WAN port speed** (Hub, router, switch) | Make sure the port between the Hub and BE25 router is capable of gigabit (1,000 Mbps or more). Also check the Ethernet cable (Cat5e or better) is used. | If the port or cable maxes out at <1 Gbps, you\u2019ll never get full speed. |\n| **Router\u2019s WAN-to-LAN throughput** | BE25 and any other routers in your setup: How fast is their NAT/firewall performance? | Even routers with gigabit ports can struggle to push full speed through networking chores. |\n| **Internal network components** | Switches, mesh nodes, wireless backhauls; also WiFi client device speed. | Slow switch or old devices will erase performance gains. |\n| **Modem mode settings** | Ensure correct WAN IP, firmware up to date, only 1 port used properly, DHCP settings, etc. | If router isn\u2019t getting correct public IP, or ports aren\u2019t forwarding correctly, it\u2019ll limit throughput. |\n| **Wireless limitations** | If most devices use WiFi, are they near the router? Are they WiFi-5/6? Are there walls, interference, shared channels? | Even with great internet, WiFi issues often cut your speeds drastically. |\n\n---\n\n## Specific Things To Try With Your Setup\n\nGiven you\u2019re using a TP-Link Deco BE25, here\u2019s what you should do:\n\n1. **Confirm whether your Hub is a 5 or 5x.**  \n   The 5 supports modem mode reliably; the 5x does not (or only partially, depending on firmware) ([comparebroadband.org.uk](https://www.comparebroadband.org.uk/virgin-media/virgin-media-hub-5-5x-explained-review-guide/?utm_source=openai)).\n\n2. **Check ports and wiring.**  \n   - Use a high-quality cable (Cat5e minimum; Cat6 or Cat6a better).  \n   - Make sure you\u2019re using the correct LAN port on Hub (usually one specified in modem mode docs).  \n   - Connect directly from Hub \u2192 BE25 WAN, avoid any switches that might only support 1 Gbps or older.\n\n3. **Router (BE25) throughput capabilities.**  \n   - The BE25 has 2.5 Gbps Ethernet ports and supports high WAN/LAN speeds\u2014good hardware. ([static.tp-link.com](https://static.tp-link.com/upload/product-overview/2024/202406/20240614/Deco%20BE25%28US%291.0_Datasheet.pdf?utm_source=openai))  \n   - But check its firmware is updated and any QoS or network filtering (firewall, parental controls, etc.) which might restrict throughput is disabled or configured well.\n\n4. **Test with wired devices.**  \n   Plug a PC/laptop directly into BE25's LAN port with a good cable. Run speed tests. If you're reaching ~900-950 Mbps (virgin\u2019s top speed) at that point, the issue is likely wireless or something downstream.\n\n5. **WiFi side \u2013 realistic expectations.**  \n   - BE25 is good, but BE-25 is a mesh; wireless connections will always be lower than wired. Even with recent reviews, BE25\u2019s maximum wireless real-world throughput drops with distance and obstacles. ([pcgamer.com](https://www.pcgamer.com/hardware/networking/tp-link-deco-be25-be5000-review/?utm_source=openai))  \n   - If most of your usage is wired, this isn't a big deal. But if you're depending on WiFi, position the units well, avoid obstructions, use 5 GHz for high-speed devices, etc.\n\n6. **Look for modem mode issues (if you\u2019re on Hub 5).**  \n   Some people report that enabling/diasbling DHCP, resetting, or temporarily putting the hub back into router mode then modem mode fixes assignment of public IP. ([zebadger.com](https://www.zebadger.com/wp/?p=326&utm_source=openai))\n\n7. **If you find you're on Hub 5x, workarounds.**  \n   - Leave it in router mode and use your BE25 as access point or downstream router.  \n   - Use the high-speed 10 Gbps port where possible for big wired traffic. ([ispreview.co.uk](https://www.ispreview.co.uk/index.php/2024/04/update-on-the-state-of-modem-mode-for-virgin-medias-hub-5x.html?utm_source=openai))  \n   - Consider asking Virgin if there\u2019s an ONT-only solution or another device rather than Hub 5x.\n\n---\n\n## Summary \u2013 Likely Situations\n\nBased on what people report:\n\n- If you have **Hub 5 (DOCSIS)** and modem mode fully functional, you *should* be able to push close to 1 Gbps via a good router and cabling.\n- If you have **Hub 5x (full-fibre/XGS-PON)**, modem mode likely isn\u2019t working properly, reducing throughput or causing routing issues that limit performance.\n\n---\n\nIf you like, I can walk you through checking what exactly you\u2019ve got (Hub 5 or 5x, firmware version, how things are currently wired) and suggest exact tweaks to get you closer to the full speed you paid for. Do you want me to guide through that?"

Let\u2019s go through what can slow things down, and what you can try.\n\n---\n\n## Key Specs to Know\n\nBefore diagnosing, ensure you know what your equipment *can* do:\n\n- **Virgin Media Hub 5** supports *modem mode* (sometimes called \u201cbridge mode\u201d) for coax-based connections. ([virginmedia.com](https://www.virginmedia.com/help/virgin-media-hub-modem-mode?utm_source=openai))  \n- **Hub 5x**, the fibre version (XGS-PON full fibre), does *not* yet reliably support modem mode everywhere. ([ispreview.co.uk](https://www.ispreview.co.uk/index.php/2024/04/update-on-the-state-of-modem-mode-for-virgin-medias-hub-5x.html?utm_source=openai))  \n- **TP-Link Deco BE25 (aka Deco BE5000)** is a WiFi-7 dual-band mesh system. It has two 2.5 Gbps network ports, which are fast enough for gigabit internet. ([rtings.com](https://www.rtings.com/router/reviews/tp-link/deco-be25?utm_source=openai))  \n\nSo: if you're using a Hub 5 (not 5x), your hardware is capable. The injuries probably lie in setup, wiring, or wireless limits.\n\n---\n\n## Where the Bottlenecks Usually Are\n\nBelow are the common limits and what to check:\n\n| Possible Bottleneck | What to Check / Test |\n|----------------------|-----------------------|\n| **Ethernet Cable Quality / WAN Link** | \u2022 Use Cat5e or Cat6 cable between Hub 5 and Deco\u2019s WAN port\u2014any older or damaged cable might limit throughput. <br> \u2022 Ensure the LAN port you use on the Hub is the correct one (usually LAN1 when in modem mode) ([comparebroadband.org.uk](https://www.comparebroadband.org.uk/virgin-media/virgin-media-hub-5-5x-explained-review-guide/?utm_source=openai)). |\n| **WAN Port Speed / Device Ports** | \u2022 Deco BE25\u2019s WAN port should support 2.5 Gbps\u2014check firmware and that you\u2019re truly using the 2.5 Gbps port. <br> \u2022 Hub-side, the single port used in modem mode must not be physically limited to 1 Gbps. Some hubs or cables may reduce speed. ([comparebroadband.org.uk](https://www.comparebroadband.org.uk/virgin-media/virgin-media-hub-5-5x-explained-review-guide/?utm_source=openai)). |\n| **Wireless vs Wired** | \u2022 Test speeds with a wired connection (plug laptop to Deco via Ethernet) so you eliminate WiFi from the equation. <br> \u2022 WiFi, even WiFi\u20107, often doesn\u2019t hit full speed at distance. Deco BE25\u2019s reviews show \u201cgood enough\u201d wireless speeds for 1 Gbps, but not always full gig in real-world conditions, especially at distance or through walls. ([pcgamer.com](https://www.pcgamer.com/hardware/networking/tp-link-deco-be25-be5000-review/?utm_source=openai)). |\n| **Modem Mode Functioning** | \u2022 Confirm Hub 5 is indeed in modem/bridge mode. <br> \u2022 Be aware some functions get disabled when in modem mode (WiFi, app-based tools etc.). ([virginmedia.com](https://www.virginmedia.com/help/virgin-media-hub-modem-mode?utm_source=openai)). <br> \u2022 If you have a Hub 5x and were told you could use modem mode, double-check\u2014support may still be rolling out. ([ispreview.co.uk](https://www.ispreview.co.uk/index.php/2024/04/update-on-the-state-of-modem-mode-for-virgin-medias-hub-5x.html?utm_source=openai)). |\n| **ISP Provisioning / External Limits** | \u2022 Even though you have a 1 Gbps plan, make sure Virgin Media is actually upgrading your line and that there\u2019s no temporary throttle in place. <br> \u2022 Test speed with a device directly connected to the Deco\u2019s WAN; compare with Virgin\u2019s own speed-test. |\n| **Firmware / Software** | \u2022 Make sure both Hub and Deco have latest firmware. <br> \u2022 Check Deco\u2019s QoS, security scanning, or any features that might limit throughput under high load. <br> \u2022 Check if Deco is in \u201crouter mode\u201d or \u201caccess point mode\u201d if relevant. |\n\n---\n\n## What Tests to Run\n\nTo isolate the issue, try this sequence:\n\n1. **Direct Ethernet test**: Connect a PC directly to the Deco via Ethernet. Run a speed test (wired). If this gives close to 900-950 Mbps, Ethernet and WAN path are probably OK.\n\n2. **Hub + Deco route test**: Hook up PC through that chain (Hub \u2192 Deco \u2192 PC). If this drops significantly, the issue might be port, cable, or Deco\u2019s WAN handling.\n\n3. **Compare Hub in router mode vs modem mode**: Sometimes performance is better in router mode, depending on firmware. Just for testing, switch modes back temporarily.\n\n4. **WiFi test close vs far**: Measure speeds while very close to Deco, then measurement in another room. Helps you see how much wireless is degrading.\n\n---\n\n## Things You Can Do to Improve\n\nHere are tweaks to try once you\u2019ve identified potential weak points:\n\n- Use Cat6 or better Ethernet everywhere, and ensure short lengths where possible.\n- If Deco and devices support it, use a wired backhaul for mesh nodes (connect through Ethernet rather than over WiFi) to keep throughput higher.\n- Turn off or reduce any non-TLS scanning, QoS or parental filters that might limit speed.\n- Update firmware on Hub, Deco, and clients (laptop, phone).\n- Position the Deco router centrally in the home if relying on WiFi; avoid too many walls or metal surfaces.\n- If Hub 5x, contact Virgin to ask about modem mode support or rollout status in your area, as this may still be being enabled. ([ispreview.co.uk](https://www.ispreview.co.uk/index.php/2024/04/update-on-the-state-of-modem-mode-for-virgin-medias-hub-5x.html?utm_source=openai)).\n\n---\n\nIf you like, I can walk you through checking your exact setup step by step (which port you\u2019re using, what cable, what firmware) to find where your particular bottleneck is. Do you want to do that?"
